多場足球模擬比賽對女子足球員發力率之影響

Purpose: The present study investigated the effect of multiple simulated soccer matches on changes in rate of force development of the knee extensors (KE) in adult women soccer players. Methods: Fifteen adult women soccer players were recruited in the study, and then were randomly assigned into control (Con, n = 8) or experimental (Exp, n = 7) groups. Exp performed the Loughborough Intermittent Shuttle Test (LIST) daily for three consecutive days, while Con did not perform the LIST. Maximal isometric contraction torque (MVC) and muscle soreness (SOR) of the KE, and rate of force development (RFD 30, 50, 100, 200) were taken before the first LIST, and 24, 48, and 72 hours after the third LIST for Exp. The aforementioned variables were measured for the Con group before, 24, 48, and 72 hours post-exercise. Results: No significant (p ＞ .05) changes in MVC, SOR, and RFD 30-200 were observed over time for Con. Changes in MVC, SOR, RFD 30, and RFD 50 after multiple LISTs for Exp were significantly greater (p ＜ .05) compared to baseline and Con. Conclusion: These results showed that female soccer players' KE RFD 30-50 were significantly reduced after multiple LISTs. Thus, these results may be used by soccer coaches and players as an early reference and application of solutions when participating in multiple soccer matches in the future.
