Fatigue effects on the knee flexors neuromuscular parameters during repeated sprinting

Abstract Background To identify at which point fatigue on neuromuscular parameters occurs in the knee flexors during a repeated sprint protocol. Methods Physical active males without previous hamstring strain injury were recruited. Neuromuscular parameters such as peak torque (PT) and rate of torque development (RTD) were assessed after every two sprints in a 5 × (2 x 30 m) repeated sprint protocol. Results Twenty physical active males participated in the study. A significant effect of sprint number was found (p
