About the study

The purpose of this study is to compare the effects of an intensity-, volume-, and time under tension-matched eccentric hamstring exercise intervention with the Romanian deadlift (RDL) and the Nordic hamstring exercise (NHE) to a sprint-specific training program on hamstring muscle architecture, volume, sprint performance, strength, and power.

Participants will be assigned to complete one of the 3 hamstring interventions for 10 weeks.
