Flywheel training has been shown to be beneficial for improving a multitude of muscle function and performance parameters, but its short-term training effects on athletic performance have yet to be established. PURPOSE: To investigate the effects of four weeks of flywheel squat training on lower body muscle function adaptations and sport-specific performance in collegiate club water polo players. METHODS: Thirteen men and women who participated in collegiate club water polo performed flywheel squat training twice a week for four weeks. Isokinetic knee extension peak power (PP) and peak torque (PT), flywheel squat peak power (FPP) and mean power (FMP), countermovement jump (CMJ), in-water jump height (WJH) and foot speed were assessed at Pre1 (0 weeks), Pre2 (4 weeks), and Post (8 weeks). Throughout the training period, muscle soreness was assessed with a visual analog scale every session, and FPP and FMP were assessed during sessions 2, 4, 6, and 8. RESULTS: Isokinetic PP (ES = .65) and PT (ES = .67) increased significantly from Pre1 to Post, and FPP and FMP increased between Pre2 and Post (ES = 1.1, 1.0 respectively), and Pre1 and Post (ES = .79, .82). CMJ and foot speed were not changed, and WJH displayed a significant change between Pre1 and Post (ES = 0.4). FPP increased 19% from session 2 to 4 and FMP increased 27% from session 2 to 6, and each remained elevated through session 8. Muscle soreness peaked at session 2 but tapered off by session 3. CONCLUSIONS: Four weeks of flywheel squat training in collegiate club water polo players elicited large gains (47-52%, Effect Size = ~1.0) in flywheel specific squat power, but did not influence sport-specific performance measures including CMJ, WJH, and foot speed. Water-based exercises and stretch-shortening cycle movements (plyometrics) in combination with effective resistance training programs, including flywheel-based training, are likely needed for marked sport skill improvements, along with longer-term training studies.
