There are various approaches to measuring muscle fatigue, including such simple measures as surveys for qualitative data, and measuring power output for quantitative data. Electromyography is consistently used to determine muscle fatigue. However, a quantitative measure of muscle recovery after exercise-induced damage is yet to be defined. The objective of this study is to measure the resonance frequency of a muscle group using a 3D laser vibrometer system and make a correlation with both elastography stiffness measurements, and with recovery of a muscle group based on standard muscle fatigue measurement techniques. Measurement of the resonance frequency of a muscle group has been successfully performed, and there is good reason to believe that the resonance frequency of the muscle group does shift after exercise-induced damage occurs. The main outcome of this study will determine whether the shift in resonance frequency of a muscle group can be used to track recovery after a damage protocol.There are various approaches to measuring muscle fatigue, including such simple measures as surveys for qualitative data, and measuring power output for quantitative data.
