Clench Muscle Experiment Essay

The objectives were to record the force produced by the clench muscle experiment listening to techno music and no music. The observations were to see if more motor unit recruitment came with techno music in the individual’s dominant hand. There were three participants used that were all females in the same range of age of 22-25. One of the individuals was a left hand dominant and the other two were a right hand dominant. A hand dynamometer was used for the BSL PRO3.7.5 software on a computer-using lesson 2 on the BIOPAC student lab program (5). Calibrations were done to set parameters for optimum data which the program needs by obtaining the maximum clench. To perform calibration, clenching as hard as the individual could for 2 seconds and then released for the rest of the 8 seconds (5). Furthermore, the data collected was delta T using the value of area from end point of 50 % clench force to point of maximal clench force as a reference. Delta T is in units of seconds that showed the length an individual’s muscle could last before more than 50% muscle fatigue accumulated. Maximum clench force was the value in kg that gave the average mean of 50% of max clench. As the muscle fatigued, the force of the individual’s muscle decreased which correlates with the delta T decreasing. The independent variable was the type of music played, which …show more content…
The maximum clench force was performed by having the individual maintain a clench at the maximum force for as long as possible. When the maximum clench force was decreased by more than 50 percent, the recording was stopped. The individual was able to rest the arm by not repeating immediately by having the other two individuals in the study to do their experiment. Each individual did three trials for each music type but the no music was done first while the techno music was done a week later so the fatigue data would be
