Is lower training frequency more effective? Dose-response relationship of in-season flywheel resistance training on vertical jump and sprint performance in male team-sport athletes: a meta analysis

Compared with TRT, FRT is more effective in enhancing CMJ performance and linear sprint speeds over specific distances in male team-sport athletes during the in-season. Training protocols characterized by low frequency (≤ 2 sessions per week) and a total of around 12 sessions appear to facilitate better athletic adaptations. Future research should include female athletes and investigate long-term interventions to further refine the application strategies of FRT in in-season training.
