Purpose: Aim to investigate the effect of kinesio tape on post-fatigue muscle of shoulder joint. Methods: 6 college second level baseball players are to test the maximum pitching speed and recoded EMG of maximum voluntary contraction. After previous test, data were recorded by surface EMG from four different muscles in pre-fatigue, post-fatigue, and after kinesio taping. Statistics: Repeated measures analysis of variance was to test the different between pre-fatigue, fatigue, and after kinesio taping. Tukey’s HSD was enrolled in finding source of difference and paired t test was used to compare change amounts of fatigue vs. pre-fatigue and after kinesio taping vs. pre-fatigue. Results: RMS of biceps brachii (18.57 ± 4.82), anterior (14.53 ± 4.07), and middle deltoid (19.33 ± 3.32) after kinesio taping are lower then fatigue (biceps: 28.72 ± 5.18; anterior: 21.66 ± 5.64; middle: 24.76 ± 7.03). All of the muscles after kinesio taping (biceps: 87.35 ± 2.41; anterior: 90.51 ± 5.23; middle: 94.22 ± 6.34; posterior: 90.65 ± 5.74) had higher median frequency than in fatigue(biceps: 77.32 ± 4.12;anterior: 79.49 ± 5.14; middle: 83.06 ± 5.26; posterior: 78.26 ± 6.15). Conclusions: Kinesio taping could increase muscle recovery rate from fatigue by increase amounts of motor units recruited and improve sport performance. Suggestions: EMG had to be more powerful to explain how muscle works after analyzed with kinematics. Thus, there were more information about mechanism of pitching for coaches, pitchers, and athlete trainers.
