As with athletes, the demands and stress on the performing musician is very high. The combination of speed, coordination, accuracy, consistency and timing create a situation in which injuries impede the successful performance by the musician. While musicians are becoming more willing to seek medical attention, there are still several factors that keep musicians from seeking medical care.1 The first is the absence of highly visible signs of injury. Most injuries of musicians are not as overt as typical athletic injuries, therefore, musicians do not seek care as readily as athletes.1 Second, musicians are often told that discomfort is inevitable. Third, musicians also often feel that the injury is their fault due to the stresses they are putting on their body. Fourth, musicians fear the risk of loss of 2 employment due to inability to play. Lastly, musicians can be reluctant because of the belief that treatment will change their technique on their instrument. While these factors are understandable, they can be associated with a lack of information or misinformation about performing arts medicine. Seeking help from a sports medicine specialist may help prevent injuries and decrease the amount of time the musician loses because of an injury. This is especially true for percussionists, because their whole body is involved in playing their instrument. A number of conclusions can be drawn regarding the effects of warm-ups on drumming performance.2 First there are two types of warm-ups, active and passive. Active warm-ups involve exercise and are likely to induce greater metabolic and cardiovascular changes than passive warm-ups. Passive warm-ups involve raising the muscle temperature or core temperature by some external means (hot pack, hot shower, etc.).2 The first conclusion that can be drawn is that active warm-ups tend to result in slightly larger improvements in short-term performance (less than 10 seconds) compared to passive heating alone. However, short-term performance may be impaired if the warm-up is too intense or does not allow sufficient recovery and results in a decreased availability of high energy 3 phosphates before starting the task.3 Active warm-ups have also been shown to improve both long-term and intermediate performance (greater than 10 seconds and less than 5 minutes) if it allows the athlete to begin the subsequent task in a relative non-fatigued state, but with an elevated VO2. While passive warm-ups have shown to improve immediate performance, both passive and active warm-ups may have detrimental effects on endurance performance.2 By manipulating intensity, duration and recovery, many different warm-up protocols may be able to achieve similar physiological and performance changes.2 While a number of physiological effects of a warm-up have been attributed to temperature-related mechanisms, other mechanisms have also been proposed (e.g. effects of acidemia, mobilization of the aerobic system and increased postactivation potentiation). Despite the above mentioned mechanisms, it appears that passive warm-up does not improve isometric force, but may improve short-duration (<10 seconds) dynamic force. There are improvements in dynamic short-term performance (e.g. vertical jumping and sprint cycling) that tend to be less than those reported for isolated muscles.4 While the mechanisms remain to be fully elucidated, it also appears that passive warm-up can improve intermediate performance (~10 seconds to 5 4 minutes). Passive warm-up does not improve, and may have a detrimental effect on long-term performance (>5 minutes), possibly via an increase in thermoregulatory strain.4 There are several protocols that may help improve warm-ups, and ultimately, performance and possibly reduce injury. There are conflicting views in regards to what is the best way to reduce injury.5 A study was performed to see if a warm-up and stretching can prevent or reduce muscular injury. Subjects studied included both male and female and trained and untrained individuals. The independent variable was the warm-up and the dependent variable was the number of injuries. The results showed contradictory evidence to the question above. In the end, there is not enough evidence to answer whether or not a warm-up or stretching can prevent muscular injury in drumming. If a drummer chooses to use a warm-up, it should be implemented prior to physical activity. Ideally, it should occur about 15 minutes prior to the activity and be tailored to the individual as well as the activity. elbow, forearm and wrist. This includes the It should produce a mild sweat, but avoiding fatigue.2 To understand how high levels of skill are developed and maintained, it is necessary to study elite groups such as professional athletes or musicians.6 A study was 5 performed in which subjects included musicians and nonmusicians. The independent variable is the musician playing at a high level. cortical activation. The dependent variable is the The results showed that being a very skilled musician can structurally change the motor areas of the brain. Philosophy, methodology and techniques are required to obtain greater performance on the drums with both hands and feet.7 A study was done that included drummers who wanted to gain greater speed with their hands and feet. The independent variables were proper biomechanical alignment of limbs, proper technique and all equipment properly aligned. The dependent variable was the speed. The results showed that by manipulating the independent variables, drummers can increase speed with their hands and feet. Subsequently, speed of drumming appears to be impacted by proper body mechanics and techniques, suggesting that warm-up protocols that impact posture and drumming technique may significantly improve speed. The purpose of this study is to examine the different effects of warm-up protocols on various skill levels while performing a single stroke roll. In the end, there is insufficient evidence to answer whether or not a warmup/stretching can prevent muscular injury, but there is 6 research that shows the potential for an increase in performance. If a warm-up is performed, it should be implemented prior to physical activity. Ideally, it should occur about 15 minutes prior to the activity and be tailored to the individual as well as the activity. 7 METHODS The purpose of this study was to examine the difference in maximal drumming speed of various skill levels dependent upon warm-up protocols. The following areas are discussed in this section: Research Design, Subjects, Preliminary Research, Instruments, Procedures, Hypotheses, and Data Analysis. Research Design A within subjects quasi-experimental design was used for this study. One independent variable of this study was the warm-up protocols: heat, stretching and rudiments. The other independent variable was the skill of the drummer: novice, amateur and professional. The dependent variable of this study was the amount of strikes on the pad in one minute. performed. On the first day, baseline drum testing was On the following days, a warm-up protocol was performed followed by drum testing. 8 Subjects The subjects (N=15) of this study were male and female drummers from California University of Pennsylvania. All subjects read and signed an informed consent form (Appendix C1) prior to participating in the study. Subjects who had current upper body injuries, or were currently taking medications that may have affected their ability to strike the pad were excluded from the study. Demographic information was obtained from the Demographic Profile Form (Appendix C2) that each subject filled out prior to participation. A Photo Consent Form was also filled out prior to participation (Appendix C3). Preliminary Research The purpose of the preliminary research was to familiarize the researcher with the instruments and warm-up protocols that were used in this study. This included familiarization with the Drumometer Model II, warm-up protocols and the testing protocol. The preliminary research also aided the researcher in deciding the amount of rest time needed in-between each test trial. In addition, the preliminary research allowed the researcher 9 to determine the amount of time required for each day of testing. The preliminary subject (N=1) was a volunteer drummer from California University of Pennsylvania. The preliminary subject was randomly assigned to one of the three previously mentioned warm-up protocols. This allowed for the researcher to carry out the procedures for each group, ensuring proper execution of each protocol. Instruments The following instruments were used in this study: a subject demographic profile form (Appendix C2), a heat warm-up protocol, a stretching warm-up protocol, a rudiment warm-up protocol (Appendix C4), a Drumometer Model II strike counter (Figure 1) and a pair of Vic Firth SD1 General drumsticks (Figure 2) and the data collection sheet (Appendix C5). Subject Demographic Profile Form The Subject Demographic Profile Form (Appendix C2) was created by the researcher. The demographic profile included age, years of experience, years of studying, specialty, hours of practicing a week, and upper body injury history. The Demographic Profile Form helped to 10 confirm that subjects did not have any current upper body injuries, or if there were on any medications that may have affected their ability to strike a pad. If volunteers answered yes to any of the questions on the Demographic Profile Form, they were excluded from the study. Heat Warm-up Protocol Based on the results of the research, thermotherapy treatment of the upper extremity have effects on the performance of the hand expressed as reaction time, speed of movement and tapping speed.8 A study performed by Bishop showed that a majority of the effects of a warm-up are due to a temperature-related mechanism.4 For the purpose of this study, a hot pack from a hydrocollator that is between 160176 degrees Fahrenheit will be applied to the top and bottom of forearms, wrists and elbows. The treatment will be applied for 12 minutes. Stretching Warm-up Protocol Common clinical practices suggest that pre-exercise stretching can enhance performance and prevent injuries by increasing flexibility. For the purpose of this study, the wrist and forearm flexors and extensors were stretched as well as finger flexors. Three stretches were performed in 11 each motion. Stretches were held for thirty seconds each. They were completed on the left and right hand. Rudiment Warm-up Protocol Often called the 'building blocks of drumming' and equated with the scales played on melodic instruments, drum rudiments consist of short rhythmic phrases with specific stickings.9 For the purpose of this study, the 13 essential rudiments will be used as described by the National Association of Rudimental Drummers (Appendix C4). Each rudiment will be performed for 30 seconds with a rest time of 5 seconds in between. This protocol will take 7 minutes and 35 seconds. Drumometer Model II The Drumometer Model II works when the pad that is being struck sends an electric signal to the Drumometer. When the pad is struck, the timer will immediately start counting down and the counter will record each stroke until the desired time has elapsed (in this study 60 seconds will be used). When the timer reaches zero, the Drumometer will stop and an alarm will sound. The number of strokes that has been played in a minute will be displayed and recorded. 12 Figure 1.

Vic Firth SD1 General Drumsticks Data Collection Sheet The Data Collection Sheet (Appendix C5), created by the researcher was used to record all relevant data for the test using the Drumometer Model II. This included the subject identification number, group assignment, date, warm-up protocol, and the results of the three trials from day one, two, three and day four of testing. Procedures The following steps were taken for this study: approval to carry out the study was acquired from the California University of Pennsylvania Institutional Review 14 Board (Appendix C6). Once the study was approved, preliminary research was conducted. After completion of preliminary research, subjects were sought to participate in the study. California University of Pennsylvania drummers were asked to volunteer to participate in the study. Subjects were educated on the details and purpose of the study. Prior to participation all volunteers were given an informed consent form to read and sign. All participants then scheduled four testing times: the first to obtain baseline data and a second through fourth to carry out their randomly assigned warm-up protocols. When subjects arrived on the first day they picked a number out of a box to obtain their randomly assigned subject number and group designation. The assigned subject number replaced the subject’s name once testing began to maintain subject anonymity. After receiving their subject number, the subjects completed the previously mentioned demographic profile form. Volunteers who revealed any current injuries or contraindications were not allowed to participate in the study. Subjects then completed one practice trial using the Drumometer Model II strike counter before they performed their actual test. The practice trial was carried out to allow the subject to familiarize themselves with the Drumometer Model II. After the 15 practice trial was completed, the subject completed the actual test. The actual test consists of three attempts with the Drumometer Model II in which the highest score was recorded. Based on observations from the preliminary research, subjects were allowed a three minute rest period between trials. The result from the official test was considered their baseline data. Results were recorded in the data collection sheet. After a minimum of one day and a maximum of seven days passed and to minimize a possible learning affect, the subjects returned for day two of testing. When subjects arrived on the second day they were instructed on how to perform the warm-up protocol assigned to them. They then completed their designated warm-up protocol: heat, stretching or rudiments. Once the subjects completed their appointed warm-up, they completed their three tests on the Drumometer Model II and the best result was recorded. After a minimum of one day and a maximum of seven days passed, the subjects returned for day three of testing. When subjects arrived on the second day they were instructed on how to perform the warm-up protocol that was randomly assigned to them. They then completed their designated warm-up protocol: heat, stretching or rudiments. Once the subjects completed their appointed warm-up, they 16 completed their tests on the Drumometer Model II. Results of the official test were recorded. After a minimum of one day and a maximum of seven days passed, the subjects returned for day four of testing. When subjects arrived on the second day they were instructed on how to perform the warm-up protocol assigned to them. They then completed their designated warm-up protocol: heat, stretching or rudiments. Once the subjects completed their appointed warm-up, they completed their test on the Drumometer Model II. Results of the official test were recorded. Hypotheses The following hypotheses were generated based on the literature review and the clinical intuition of the researcher. 1. There will be a difference in maximal drumming speed dependent upon warm-up protocols. 2. There will be a difference in maximal drumming speed dependent upon skill level. 3. There will be an interactive effect between warm-up protocol and skill level upon maximal drumming speed. 17 Data Analysis A 3 x 3 factorial ANOVA (analysis of variance) was used to determine the effect of the independent variables (type of warm-up protocol and skill level) on the dependent variable (strikes per minute). This will examine both the main effects and the interaction. If a difference is found, post hoc testing was to be conducted to analyze the patterns. The dependent variable, strikes per minute, was used to calculate a difference in the warm-up protocols. This was calculated by subtracting the day 1 baseline test from the day 2, day 3 and day 4 test score. An alpha level of P < 0.05 was used to determine statistical significance. SPSS 17.0 was used for this statistical analysis. 18 RESULTS The purpose of this study was to examine the difference in maximal drumming speed of various skill levels dependent upon warm-up protocols. The following section contains the data collected through the study and is divided into three subsections: Demographic Information, Hypotheses Testing and Additional Findings. Demographic Information Subjects included volunteer drummers who were students at California University of Pennsylvania. There were 3 beginners, 4 intermediate and 8 advanced drummers. Participants indicated three main areas of focus; 6 were specialized in drum set, 8 were specialized in drumline and 1 was specialized in the hammered dulcimer. 19 Hypothesis Testing Mean drumming speed of the three participant skill levels under the three warm-up conditions can be found in table 2. The following hypotheses were tested in this study and determined if the main effect of skill level and warm-up had a significant effect on performance. All hypotheses were tested with a level of significance set at α ≤ 0.05. Differences were examined utilizing one 3 x 3 factorial ANOVA with repeated measures for the effect of various warm-ups on maximal drumming speed of various skill levels. Interactions between the independent variables of warm-up and skill levels were also examined. Hypothesis 1: There will be a difference in maximal drumming speed dependent upon warm-up protocols Conclusion: A 3 x 3 repeated measures factorial ANOVA was calculated to examine the effect of warm-up protocols on maximal drumming speed. No significant within subject main effect of warm-ups was found. The effect of warm-ups (F(2,24) = 1.346, p > .2.79) on drumming speed was not significant. 20 Hypothesis 2: There will be a difference in maximal drumming speed dependent upon skill level Conclusion: A 3 x 3 repeated measures factorial ANOVA was calculated to examine the effect of skill levels on maximal drumming speed. No significant between subject main effect of skill level was found. The skill levels (F(2,12) = .894, p > .434) on drumming speed was not significant. Hypotheses 3: There will be an interactive effect between warm-up protocol and skill level upon maximal drumming speed. Conclusion: A 3 x 3 repeated measures factorial ANOVA was calculated to examine the interactive effect of warm-up protocol and skill level on drumming speed. interactive effect was found. No significant The interaction (F(4,24) = 1.689, p > .185) was not significant. 21 DISCUSSION The general purpose of this study was to examine the different effects of warm-up protocols on various skill levels while performing a single stroke roll. The following section is divided into three subsections: Discussion of Results, Conclusions, and Recommendations. Discussion of Results Investigations into whether there was a difference in drumming speed of various skill levels dependent upon warmup protocols showed no significant difference in performance. A 3 x 3 repeated measures ANOVA was calculated to examine the effects of warm-up protocols and skill levels on maximal drumming speed. The warm-up protocol and skill level interaction (F(4,24) = 1.689, p > .185), warm-up protocol (F(2,24) = 1.346, p > .279), and skill levels (F(2,12) = .894, p > .434) were not significant. 22 Table 1. Results of 3 x 3 Repeated Measures ANOVA F Significance (p > .05) Warm-up Protocols 3.012 .108 Skill Levels .690 .521 Interactive Effect .894 .434 Source Table 2 shows the mean strikes per minute for each skill level and warm-up protocol. The beginner skill level had a mean between 585.33-596.33 strikes per minute depending upon the warm-up protocol, while the intermediate skill level had a mean between 667.50-701.50 strikes per minute depending upon the warm-up protocol and finally the advanced skill level had a mean between 716.00-725.75 strikes per minute depending upon warm-up protocol. This is consistent with what the researcher hypothesized stating that there will be a difference in maximal drumming speed dependent upon skill level. One thing that needs to be considered is the standard deviation. Due to the large standard deviation, anywhere from 46.446-118.024, there is an overlapping effect between skill levels. A possible conclusion that can be drawn is that while the majority of 23 the subjects fell into the appropriate skill category, a few subjects caused an overlap of the skill level means. This shows that the skill levels did not always coincide with the years of experience playing drums. Therefore it may be beneficial to examine a better way to classify skill levels than years of playing experience. Table 2. Mean Drumming Scores Skill Beginner Intermediate Advanced Heat (SD) Stretching (SD) Rudiments (SD) 593.6 (80.21) 585.3 (69.42) 596.3 (92.87) 667.5 (111.88) 701.5 (108.50) 689.2 (118.02) 717.0 (46.44) 716.0 (50.00) 725.7 (49.56) It was hypothesized that there would be a difference in maximal drumming speed dependent upon warm-up protocols. As the mean drumming scores for heat was examined, a mean range of 593.6-717.0 with a standard deviation between 46.44-111.88 dependent upon which skill level they were classified as. When statistically analyzing the heat score and performance, it was discovered that there was no significance. When stretching was analyzed, the mean was between 585.3-716.0 with a standard deviation between 24 50.00-108.50. difference. This too was shown not to have significant Finally, rudiments were examined. The rudimental mean was between 596.3-725.7 with a standard deviation between 49.56-92.87. Once again, no significance was found. The researcher hypothesized that there would be an interactive effect on differing groups dependent upon the warm-up protocols. It was thought that all skill levels would be effected by heat due to the physiological changes that are caused by heat on the body, such as a decreased resistance of muscles and joints and an increase in release of oxygen.2 It was also thought that the beginner skill level would be most affected by stretching due to the tendency of beginning drummers to tense up while performing on the Drumometer Model II. While all skill levels can tense up while playing, intermediate and advanced players have the ability to stay more relaxed than beginners. Lastly, it was thought that the advanced skill level would perform better when rudiments where performed because of the coordination that the rudiments provide. Advanced players performed the rudiments more proficiently than the beginners or intermediate skill levels, so it was thought that they would benefit the most by possibly striking the Drumometer Model II in a more efficient manner. However, 25 after performing the research and statistical analysis, it was discovered that no significant interactive difference was found between skill levels and warm-up protocols. The results are surprising due to the literature that on performance and warm-ups. Research has shown that an active warm-up can possibly improve both long-term and intermediate performance (longer than 10 seconds and less than 5 minutes if it allows the athlete to begin the subsequent task in a relative non-fatigued state.2 In this study, testing was only 1 minute long so it falls under this category, it also lets the subjects begin in a nonfatigued state. Studies have also shown that the majority of effects of warm-ups have been attributed to temperaturerelated mechanisms, such as decreased stiffness, increased nerve-conduction rate and an increased anaerobic energy provisions, which was attempted during this study.4 The results also showed a possible learning effect. Each day of testing, the subject was given three chances to strike the Drumometer Model II with as many single strokes as possible. The majority of subjects struck the Drumometer Model II with the most strikes on their third attempt and had the fewest amount of strikes on their first attempt. Table 3 shows this possible learning effect where H1 (heat first attempt) is generally less than H3 (heat 26 third attempt). This table does not take into account the scores that were disqualified due to double strokes. Table 3.

Rudiments are designed specifically to increase hand coordination and this coordination may help improve the accuracy of the strikes on the Drumometer Model II. The physiological effects of heat may play a vital role in increasing muscle endurance while striking the Drumometer Model II. Stretching may also play a role timing and coordination by increasing range of motion. 27 Conclusions The findings of this study show that neither heat, rudiments or stretching had a significant effect on maximal drumming speed on drummers of various skill levels. However, the trends seen in the results showed that further investigation is needed on this topic. This may include testing the effects of warm-ups on factors other than speed, such as timing, accuracy, endurance, and coordination. Nevertheless, research still supports the use of warm-ups to increase performance. It was shown that active warm-ups can possibly result in slightly larger improvements in short-term performance (less than 10 seconds) compared to passive heating alone. However, short-term performance may be impaired if the warm-up is too intense or does not allow sufficient recovery and results in a decreased availability of high energy phosphates before starting the task.3 Active warm-ups have also shown to improve both long-term and intermediate performance (greater than 10 seconds and less than 5 minutes) if it allows the athlete to begin the subsequent task in a relative non-fatigued state, but with an elevated VO2. While passive warm-ups have shown to improve immediate 28 performance, both passive and active warm-ups may have detrimental effects on endurance performance. By manipulating intensity, duration and recovery, many different warm-up protocols may be able to achieve similar physiological and performance changes. Recommendations The findings of this study show that using neither heat, rudiments or stretching as a warm-up had a statistically significant effect on maximal drumming speed. As for future research, it is suggested to work to minimize the learning effect. This can be done by having subjects come in for a drum lesson on the Drumometer Model II before they start their baseline testing. This would help them get acquainted with the equipment and used to playing the single stroke roll and the 13 essential rudiments. It is also recommended to find a more sufficient way to divide up the groups into skill levels. In this study people playing up to 4 years were considered beginners. People playing 5-9 years were considered intermediate players, and finally, people who have been playing for 10+ years were considered advanced. This did not necessarily 29 reflect the results that were received as shown by the overlap in numbers. 30 REFERENCES 1. Branfonbrener AG. Performing arts medicine.

As with athletes, the demands and stress on the performing musician is very high. The combination of speed, coordination, accuracy, consistency and timing create a situation in which injuries are prevalent. Many variables must be considered when analyzing the potential for injury in artistic performance. The variables in performing arts medicine can be broken down into two categories. The first being the capabilities and limits of each instrument and the musician themselves.1 The capabilities and limits of each instrument are relative constants, and for this reason, generally predictable. The musician, on the other hand, is very unpredictable, because each artist has his or her own strengths and weaknesses. A common misconception is that playing an instrument is a natural action.2 From a 34 physiological standpoint, playing an instrument is not a natural or automatic behavior for the body. Due to these variables, injuries can occur and the need for a medical professional may be necessary. While musicians are becoming more willing to seek medical attention, there are several factors that keep musicians from seeking medical care.1 The first is the absence of highly visible signs of injury. Most injuries of musicians are not as overt as typical athletic injuries, therefore, musicians do not seek care as readily as athletes.1 Second is the fact that musicians are often told that discomfort is inevitable. Third, musicians also often feel that the injury is their fault due to the stresses they are putting on their body. Fourth, musicians fear the risk of loss of employment due to inability to play. Lastly, musicians can be reluctant because of the belief that treatment will change their technique on their instrument. While these factors are understandable, they can be associated with a lack of information or misinformation about performing arts medicine. Seeking help from a sports medicine specialist may help prevent injuries and decrease the amount of time the musician loses because of an injury. This is especially true for 35 musicians, such as percussionists, because their whole body is involved in playing their instrument. Being a percussionist is a very physically demanding activity. Percussionists will spend countless hours working on increasing speed, endurance, power, timing, consistency and accuracy. Beyond just playing, one must take into account the factor of travelling, the number of shows and rehearsals being performed, the weight of the gear being transported, little sleep and poor nutrition. Even with great technique, these demands can lead to fatigue and injury. Biomechanics Drumstick grip is the first technique that should be discussed. There are three main types of grips: grip, traditional grip, and the French grip. the match This study will be done using the match grip due to its high prevalence among drummers. hands mirror each other. While using match grip, both The key to remember is that the drummer must remember to stay relaxed as tension and drumming do not mix at all. Shoulders and upper arms should always be in a natural position. The elbow should 36 be very relaxed, but not laying against the body. Once the hands are loose, speed and power will follow. The first step in the match grip is to leave an inch and a half of the stick out of the back of the hand. re-set the “fulcrum point.” Next, The point between the thumb and first finger is known as the “fulcrum” or balancing point. Now, picture a line splitting the stick in half horizontally. The thumb can sit on top of the imaginary line or in the middle of it. The three back fingers lay relaxed wrapped around the stick. There is a tendency to leave the pinky and ring finger off the stick when they play. If this happens; it can hinder future advanced control capabilities. discussed. Once this is done, the wrist must be Some teachers like it parallel to the ground, some like the thumb straight up, and some like it in between. The final step is to setup the left hand exactly like the right hand. Before the drum is struck, the drumsticks should form the letter “V” above the drumhead. should be about an inch apart. inches above the drumhead. The tips of the sticks Hold the drumsticks 3 Starting with your right hand, move your wrist (not your arm) to raise the stick 6-8 inches above the drumhead (this is known as the up position). Strike the drumhead lightly just forward of the 37 center with a quick down-up motion and let the wrist return the stick to the up position. Repeat with the left hand, and make sure that you strike each stick with equal force. Knowledge of anatomy and biomechanics of the hand are important to have a successful hand examination and assessment.3 A study was performed to examine the truth of this. The only restriction to be a subject in this study was that you had to experience trauma to the hand. ages and races were included in this study. All The independent variable was the special tests used during the hand examination while the dependent variable was the injuries that were missed due to bad examinations. The results showed that the better the examinations are, the fewer amounts of injuries you miss. It is imperative to have a great understanding of anatomy to perform a successful hand examination. To better understand this, the human rate limit for voluntary rhythmic movement must be examined. As the human rate limit for voluntary rhythmic movement was examined, it was assumed that the movement was between 5-7Hz, but there has been recent report that a drummer won a contest by moving his wrists at a rate of 10Hz.4 The subjects of this study included drummers, nondrummers and the world’s fastest drummer. The independent 38 variable was the skill of the drummer and the dependent variable was the taps per minute that the drummers performed. The results showed that a greater skill level can produce a movement greater than 7Hz. To accomplish this one must keep the wrist compliant and not stiff. The question here is whether or not a warm-up routine can help increase your speed. Warm-up Routines and Performance While there is a scarcity of well controlled studies with large subject numbers and appropriate statistical analysis, a number of conclusions can be drawn regarding the effects of warm-ups on drumming performance.5 First there are two types of warm-ups, active and passive. Active warm-ups involve exercise and are likely to induce greater metabolic and cardiovascular changes than passive warm-ups. Passive warm-ups involve raising the muscle temperature or core temperature by some external means (hot pack, hot shower, etc.). The first conclusion that can be drawn is that active warm-ups tend to result in slightly larger improvements in short-term performance (less than 10 seconds) compared to passive heating alone.5 However, shortterm performance may be impaired if the warm-up is too 39 intense or does not allow sufficient recovery and results in a decreased availability of high energy phosphates before starting the task. Active warm-ups have also shown to improve both long-term and intermediate performance (greater than 10 seconds and less than 5 minutes) if it allows the athlete to begin the subsequent task in a relative non-fatigued state, but with an elevated VO2.6 While passive warm-ups have shown to improve immediate performance, both passive and active warm-ups may have detrimental effects on endurance performance. By manipulating intensity, duration and recovery, many different warm-up protocols may be able to achieve similar physiological and performance changes. A study performed by Bishop showed that a majority of the effects of a warm-up are due to a temperature-related mechanism. The subjects were both male and female and trained and untrained individuals. variable was a warm-up. The independent The dependent variable was the measured results of the performance. The results showed that the warm-up effects can be due to a temperaturerelated mechanism. While it has been hypothesized that warm-ups may have a number of effects, the majority of the effects of warm-up have been attributed to temperaturerelated mechanisms as shown in Table 4 and 5.6 40 Table 6. Temperature Related Effects of Warm-ups Temperature Related Effects Decreased resistance to muscles and joint Greater release of oxygen from hemoglobin and myoglobin Speeding of metabolic reactions Increased nerve conduction rate Increased thermoregulatory strain Table 7. Non-Temperature Related Effects of Warm-ups Increased blood flow to muscles Elevation of baseline oxygen consumption Postactivation potentiation Psychological effects and increased preparedness However, other mechanisms have also been proposed (e.g. effects of acidemia, mobilization of the aerobic system and increased postactivation potentiation). Despite the above mentioned mechanisms, it appears that passive warm-up does not improve isometric force, but may improve short-duration (<10 seconds) dynamic force. There are improvements in dynamic short-term performance (e.g. vertical jumping and sprint cycling) that tend to be less than those reported for isolated muscles. While the mechanisms remain to be fully elucidated, it also appears that passive warm-up can improve intermediate performance (~10 seconds to 5 minutes).6 Passive warm-up does not 41 improve, and may have a detrimental effect on, long-term performance (>5 minutes), possibly via an increase in thermoregulatory strain. There are several protocols that may help improve warm-ups, and ultimately, performance. Warm-up Protocols Heat The first study of the effects of hot and cold pack treatments on the motor performance of the upper extremity showed that hot and cold pack treatments had an effect on the motor performance of the hand indicated by reaction time, speed of movement and tapping speed. Both hot and cold pack treatments delayed simple reaction time. With cold packs this was an expected reaction because of decreasing performance of the extension muscles of the forearm. However, with hot pack treatment the same phenomenon was a surprise, because warming can decreases joint stiffness and increases blood flow and collagen extensibility. Based on the results of the research, hot and cold treatment of the upper extremity have effects on the performance of the hand expressed as reaction time, speed of movement and tapping speed.7 Although hot and cold packs 42 affect motor performance, cold packs negatively affect speed of movement and tapping speed while hot packs significantly improved taking speed. Moreover, hot packs increased tapping speed immediately and 30 minutes later. These changes were emphasized on fine motor movements of the finger performed with fast back-and-forth movement of antagonistic muscles. On the other hand, reduction in fine hand function may be insignificant when dealing with gross musculoskeletal function and the need to reduce pain, which stretching may help with. Stretching It is a common practice to use pre-exercise stretching to enhance performance and prevent injuries by increasing flexibility. However, a recent review article does not support this notion.9 Research was done where the different types of stretching performed before performance were looked at and their results on performance. The results state there is limited scientific data to support the suggested benefits of stretching. Despite stretching commonly being performed before exercise to enhance performance and reduce the risk of injury, there is limited scientific data to support the suggested benefits of stretching. 43 Static and ballistic stretching have been shown to have detrimental effects on muscle strength and functional performances such as jumping, and to have inconclusive effects on the incidence of injury, and no effects on the severity of muscle damage. Even though research has indicated that stretching is an effective treatment to increase static flexibility (range of motion), the effects on dynamic flexibility (muscle stiffness) are inconclusive given the variation of the length of hold and the number of repetitions used in studies. In the world of sports, stretching has recently undergone a transformation from a generally assumed aspect of training to a more scrutinized contributor that may or may not be supported by the outcome of enhanced sport performance.9 The aim of stretching is to increase flexibility, but the question of whether flexibility helps to enhance performance has not been answered. The ideal flexibility for the performance of each sports activity is different. Compliant muscle fibers might be beneficial to eccentric contraction while stiffer muscle fibers might be more suitable for concentric and isometric contractions.10 Does flexibility help to reduce the rate of injury? The majority of research does not support this statement. Stretching can also affect strength performance. 44 Many activities rely heavily on strength, but strength performance may be diminished by a preceding stretching routine; therefore, it is important to understand the phenomenon when prescribing physical exercise programs.11 There appears to be substantial evidence suggesting a decrease in strength following stretching. Studies used different stretching techniques, duration and targeted different muscle groups, and were tested with isotonic, isometric and isokinetic devices. However, the number of exercises, duration of each exercise and number of sets was much longer than the ranges normally used in practice. Another protocol that may increase speed is the use of rudiments. Rudiments Often called the 'building blocks of drumming' and equated with the scales played on melodic instruments, drum rudiments consist of short rhythmic phrases with specific stickings.12 The first set of standardized drum rudiments was created by the National Association of Rudimental Drummers (NARD) in 1933 and consisted of 26 rudiments that were considered essential by its members. The Percussive Arts Society (PAS) expanded this set in 1984 by compiling a list 45 of 40 International Drum Rudiments, which included the original 26 NARD rudiments, along with drum corps, European, orchestral and contemporary snare drum rudiments that had become popular. Many drum set players use rudiments for technique development and adapt rudiments to other styles of music. Jazz drummers such as Buddy Rich and Joe Morello often displayed a rudimental influence; rock drummer Spencer Dryden played a rudimental-style snare drum introduction on Jefferson Airplane's 1960s hit 'White Rabbit'; and Steve Gadd's drum part on Paul Simon's 1970s hit '50 Ways to Leave Your Lover' was rudimentally based.12 Injuries Warm-up and prevention Muscular injury is one of the major problems facing today’s athletes and musicians, both recreational and professional. Injuries to skeletal muscle represent greater than 30% of the injuries seen in sports medicine clinics.13 As a result, it is imperative to utilize the most effective means to aid in deterring these injuries. However, there are conflicting opinions regarding methods of reducing muscular injury through warm-up and stretching techniques. 46 There are conflicting views in regards to what is the best way to reduce injury.14 This study was done to see if a warm-up or stretching can prevent or reduce muscular injury. Subjects studied included both male and female and trained and untrained individuals. The results showed contradictory evidence to the question above. In the end, there is not enough evidence to answer whether or not a warm-up/stretching can prevent muscular injury. If a drummer chooses to use a warm-up, it should be implemented prior to physical activity. Ideally, it should occur about 15 minutes prior to the activity and be tailored to the individual as well as the activity. elbow, forearm and wrist. This includes the It should produce a mild sweat, but avoiding fatigue. Elbow forearm and wrist Competitive and recreational athletes sustain a wide variety of soft tissue, bone, ligament, tendon and nerve damage to their upper extremities.15 Most such injuries are related to direct trauma or repetitive stress, and account for a significant amount of ‘down time’ for athletes participating in a wide range of sports, particularly those in which the arm is utilized for throwing, catching or swinging. Overuse injuries to the elbow include 47 musculotendinous injuries, ulnar nerve injuries and ligamentous injuries.15 Osteochondrol lesions of the capitullum and posterior impingement injuries in the joint are frequently seen in athletes as well. Acute traumatic injuries to the elbow include tendon ruptures, elbow dislocations and intra-articular fractures. Forearm overuse injuries in athletes include fracture of the carpal scaphoid, fracture of the hook of the hamate, Kienbock’s syndrome and pisoquetral syndromes. Ligamentous injuries include scapholunate, lunotriquetral and midcarpal instability injuries. Injuries to the distal radio-ulnar joint and triangular fibrocartilage are also quite common in athletes, and require careful evaluation and treatment. Epicondylar injuries are another common elbow injury that has been studied.16 The subjects studied were athletes mostly from golf, tennis and baseball. The independent variable was the treatment received (NSAIDs, corticosteroids, massage, laser therapy, acupuncture, strengthening, shockwave therapy and mobilizations). The results showed controversy as to what was the best treatment, and further research needs to be done to demonstrate the best treatment for epicondylar injuries. Further distally, hand and wrist injuries need to be discussed. 48 Evaluating hand and wrist injuries depends on knowledge of basic anatomy and biomechanics of the hand and wrist.17 The wrist is composed of two rows of carpal bones. Flexor and extensor tendons cross the wrist to allow function of the hand and digits. The ulnar, median, and radial nerves provide innervation of the hand and wrist. A systematic primary and secondary examination of the hand and wrist includes assessment of active and passive range of motion of the wrist and digits, and dynamic stability testing. The most commonly fractured bone of the wrist is the scaphoid, and the most common ligamentous instability involves the scaphoid and lunate. An example of a common wrist injury would be carpal tunnel syndrome. Carpal Tunnel Syndrome It is very important to assess the value of a history and physical exam findings in diagnosing carpal tunnel syndrome.18 Subjects studied included males and females with wrist pain and/or neurological symptoms. The independent variable was the diagnostic tests that were used in the study. each test was. The dependent variable was how accurate The results showed that a Tinnel’s sign with a positive hand pain diagram was the best predictors of carpal tunnel syndrome. It was also found that Phalen’s 49 was the worst predictor of carpal tunnel syndrome and age may play an issue in carpal tunnel syndrome. Carpal tunnel syndrome has an increased rate among people whose occupation involves repeated flexion and extension.19 A study was done to see how prevalent carpal tunnel syndrome (CTS) is in the presence of wrist flexion and absence of repetitive movements. The subjects were males and females who did not have a history of CTS. The independent variable is the tests that were used to help diagnose CTS. The dependent variable is how effective each test was on diagnosing CTS. The results showed that the positioning of the wrist in flexion, in the absence of repetitive movement in the hand, can cause CTS. This is presumably due to an increase in intracarpal pressure during prolonged position of flexion of the wrist or due to compression by the proximal edge of transverse carpal ligament. Performance Athletics The wrist joint and how humans control their wrists have been studied extensively. baboons were studied. In this study humans and Knowledge of the periphery, from 50 biomechanics, muscle properties and motor unit recruitment, is quite sufficient to allow us to understand movement of the forearm. Knowledge of the central control, including the spinal cord circuitry and the supraspinal centers, is, by contrast far from adequate. Some peripheral diseases, such as occupational dystonia, have frequently been suggested to arise from excessive use of forearm muscles and joints. This also relates to the art of drumming. Drumming To understand how high levels of skill are developed and maintained, it is necessary to study elite groups such as professional athletes or musicians.20 This can lead to the rediscovery of arcane knowledge that has fallen into neglect through a lack of appreciation of its significance. A study was done in which subjects included were musicians and non-musicians. The independent variable is the musician playing at a high level. is the cortical activation. The dependent variable The results showed that being a very skilled musician can structurally change your motor areas of the brain. In the end, the combination of functional MRI with its high spatial resolution and magnetoencephalography (which provides excellent temporal resolution) has made investigation of the effects of 51 training on cortical activity patterns a realistic proposition. As we have seen, by comparing instrumentalists of a professional standard with amateurs and with nonmusicians, it has been possible with these techniques to observe the effects of hand training on activity patterns within the regions of the cortex devoted to motor control. Philosophy, methodology and techniques are required to obtain greater speed on the drums with both hands and feet.21 Subjects included drummers who wanted to gain greater speed with their hands and feet. The independent variables were proper biomechanical alignment of limbs, proper technique and all equipment properly aligned. The dependent variable was the speed and how much it increased with the independent variables. The results showed that if all the independent variables are used, you can increase your speed with your hands and feet. Being able to develop incredible speed is complicated but can be understood and natural in its practice and application. The dynamic motor ability of individual fingers was also investigated under four different finger tapping conditions.22 These were: maximum speed tapping with one finger (single-finger tapping), alternate movement of two fingers (double-finger tapping), double-finger tapping in an unsupported condition, and submaximal constant speed 52 tapping with one finger in a passive manner. Subjects included 12 healthy male individuals ranging in age from 18-32. The independent variable was when the finger movement was accompanied by an alternate movement of another finger. the finger(s). The dependent variable was the speed of The results showed that when accompanied by an alternate movement of another finger, the fingers were slower than if there was just a single finger movement. In conclusion, it was found that the index finger attained the fastest cadence and greatest movement velocity, followed by the middle, little and ring fingers, respectively. Speed A study was done to investigate tapping speed asymmetry in 13 right-handed drummers and 13 right-handed non-drummers.23 The subjects included 13 right-handed drummers and 12 right-handed non-drummers. The independent variable was the level of the drummers (experience versus no experience). The dependent variable was the speed. The results showed no difference in the drummers versus non drummers in the right hand, but showed a significant difference in speed in the left hand (drummers had a higher speed). In conclusion, these results suggest that the tapping speed of the non-preferred hand progressed nearly 53 to the level of the preferred hand through daily drum training. Conclusion During the past decade, previously unmet medical needs of performing artists have fostered the rise of a new medical subspecialty: performing arts medicine.1 The increasing number of reported performance-related injuries plays a part in this as well as the musicians willingness to seek medical attention. As with sports athletes, the physical demands and stresses on the performing musician are very high. The combination of speed, coordination, accuracy, consistency and timing create a situation in which injuries are prevalent. There are conflicting views in regards to what is the best way to reduce injury and increase performance.14 In the end, there is insufficient evidence to answer whether or not a warm-up or stretching can prevent muscular injury, but there is some research that shows the potential for a relationship between warm-up and performance. If one chooses to use a warm-up, it should be implemented prior to physical activity. Ideally, it should occur about 15 54 minutes prior to the activity and be tailored to the individual as well as the activity. 55 APPENDIX B The Problem 56 THE PROBLEM Statement of the Problem Seeking help from a sports medicine specialist may help prevent injuries and decrease the amount of time the musician loses because of an injury. This is especially true for musicians, such as percussionists, because their whole body is involved in playing their instrument. One of the issues that presents itself is the lack of information on warm-ups and their effects on performance and injury prevention. If this is combined with the contradictory evidence found in studies, a problem presents itself. The purpose of the study is to examine the difference in maximal drumming speed of various skill levels dependent upon warm-up protocols. It is important to examine this relationship so athletic trainers working in the performing arts can decide what warm-up can possibly increase speed on a single stroke roll. Additionally, it would be beneficial for drummers to know which types of warm-up can increases their speed. 57 Definition of Terms The following definitions of terms will be defined for this study: 1) Rudiment – a basic drum patterns which are the basic building blocks of drumming. 2) Single Stroke Roll - the most basic rudiment which alternates R and L hits. 3) Sticking – a series of R’s and L’s combined to make a pattern where R stands for Right and L stands for Left. Basic Assumptions The following are basic assumptions of this study: 1) The subjects will be honest when they complete their demographic sheets. 2) The subjects will perform to the best of their ability during testing sessions. 3) The Drumometer Model II will be calibrated correctly. 58 Limitations of the Study The following are possible limitations of the study: 1) The validity of the single stroke roll test has not been established as a measure of drumming competence. 2) Subjects can be inconsistent in their effort during testing. Significance of the Study Since the rise of performing arts medicine, musicians are becoming more willing to seek medical attention. With the lack of studies on the subject of warm-ups on the single stroke roll and the contradictory results, this study is designed to help bring clarity as to whether or not a warm-up, and which warm-up, of a single stroke roll. will increase the speed Since single stroke rolls are one of the basic building blocks of drumming, this is an important concept. The results of this study will mean that percussionists will know whether heating, stretching or rudiments can possibly be used as a warm-up to increase their speed on a single stroke roll. It will also show how much each warm-up protocol increased their speed. The question of what warm-up protocol will have a positive 59 effect on various skill levels is important so percussionists can have a time efficient and beneficial warm-up. What this means is that the same warm-up protocol may not have the same benefits between different skill levels. This study is designed to show what warm-up protocol, if any, is beneficial at each skill level and by how much speed is increased. If a subject at a certain skill level has been using an ineffective warm-up, the goal of this study is to present them with an idea of how they can increase their speed by changing their warm-up protocol. 60 APPENDIX C Additional Methods 61 APPENDIX C1 Informed Consent Form 62 Informed Consent Form 1.

The title of the research is, “The difference in drumming speed of various skill levels dependent upon warm-up protocols.” 2. I have been informed that the purpose of this study is to discover the difference in drumming speed of various drummer skill levels following 3 different warm-up protocols. I understand that I must be 18 years of age or older to participate. I understand that I have been asked to participate along with other drummers because I have had no shoulder, arm, elbow, forearm, wrist or hand injuries within the last 6 months nor am I taking any medication that may affect my ability to strike the Drumometer Model II such as Sudafed for a cold or Benadryl for allergies. 3. I have been invited to participate in this research project. My participation is voluntary and I can choose to discontinue my participation at any time without penalty or loss of benefits. My participation will involve performing a single stroke roll test using the Drumometer Model II for 60 seconds after performing a warm-up protocol. I will be tested immediately after the warm-up protocol is finished. My participation in this study will consist of four days of participation starting with an orientation meeting and baseline testing on day one. Day’s 2-4 will consists of different warm-up protocols, which will include heat, stretching and rudiments. Heat will be applied to the top and bottom of forearms, wrists and elbows. It will be applied for 12 minutes before performing the single stroke roll test. Stretching will include the fingers, wrists and forearms and will be done for 30 seconds each. The 13 essentials rudiments will be performed for 30 seconds each with a rest time of 5 seconds in between. Each day will take approximately 30 minutes for a total of 2 hours. 4. I understand there are foreseeable risks or discomforts to me if I agree to participate in the study. With participation in a research program such as this there is 63 always the potential for unforeseeable risks as well. The possible risks and/or discomforts include possible soreness from stretching, and discomfort from a hot pack. The researcher will stand by closely during the warm-up and testing in case I need help. 5. I understand that, in case of injury, I can expect to receive treatment or care in Hamer Hall’s Athletic Training Facility. This treatment will be provided by the researcher, Micah Holland, under the supervision of the CalU athletic training faculty, all of which can administer emergency care. Additional services needed for prolonged care will be referred to the attending staff at the Downey Garofola Health Services located on campus. 6.

West, PhD, ATC Date: May 2010 Research type: Master’s Thesis Context: There is a lack of information on warm-ups and their effects on performance and injury prevention. If this is combined with the contradictory evidence found in studies, a problem presents itself. Objective: The purpose of this study is to examine the difference in maximal drumming speed of various skill levels dependent upon warm-up protocols. Design: A within subjects, quasi-experimental design Setting: Controlled laboratory setting Participants: 15 volunteering California University of Pennsylvania students who play drums and have no upper extremity injuries or are taking any medications that would affect their ability to strike the Drumometer Model II. Interventions: Subjects were tested on 4 different days. The first day was a baseline test. The test included hitting the Drumometer Model II as fast as they could for 60 seconds. 3 attempts were given with a 3 minute rest in between. The second day began with a warmup protocol; heat, stretching or rudiments and then the same testing was completed with the Drumometer Model II. On the third day, another warm-up protocol was performed and then the same drum testing. On the fourth 95 day, the last remaining warm-up protocol was performed and then the subject was tested with the Drumometer Model II. Main Outcome Measures: Number of strikes on the Drumometer Model II during a 60 second period of time. Results: The results showed that there was no significant difference between the warm-up protocols on maximal drumming speed. There was also no significant difference between the warm-up protocols on various skill levels. Conclusion: Drummers who are looking only to improve their speed should chose a warm-up of their choice since neither heat, stretching and rudiments was shown to be significant. Word Count: 297
