| Abstract |
Fourteen professional violin players volunteered in this study to investigate the relationship between self-perceived exertion level and an objective measurement of muscle fatigue before and after rehearsal sessions. Training-induced exertion was evaluated by the Borg scale ratings. Surface electromyography (EMG) was used to record the fatigue level of the upper trapezius muscles before and after a training session. Medium frequency (MF) signals were selected from the EMG recordings and used to document the fatigue rate of this muscle. A 79% prevalence of playing-related musculoskeletal complaints was found, with the neck and shoulder region accounting for 57.1% of the areas reported. There was also a significant increase in self-perceived exertion fatigue after the training session. Regression analysis revealed no significant difference in the slopes of MF on both trapezius muscles, before and after the training sessions. The disparity in the subjective perception with the objective findings indicated that the violinists' self-perceived exertion arises from multiple sources. |
