Effects of Strength Training with Inertial Devices and Subsequent Detraining in Female Professional Futsal Players

This study aimed at evaluate the effects of strength training with inertial devices on the performance and body composition of female professional futsal players, and the subsequent detraining period. Eleven players from a first division Spanish league participated in six weeks of supervised training, followed by four weeks of strength training cessation. Specific on-court training was maintained throughout. Body fat percentage decreased after the intervention and remained low after detraining. Jump performance increased after the intervention and after detraining. Sprint performance was improved in the 5-, 10- and 20-meter distances only after the intervention. Velocity and power outcomes during the squat exercise showed significant improvement after the intervention and after detraining. Six weeks of twice-weekly strength training using inertial devices could be an optimal way to improve performance and body composition. These improvements were maintained after a four-week detraining period, during which the players only trained on the futsal court.
