What this study is
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.
What's being tested
- RDL
Intervention · OTHER
The RDL will be performed with a 6 second eccentric component with the athlete returning to the start position with a maximal concentric hip extension.
- NHE
Intervention · OTHER
The NHE will be performed with a 6 second eccentric component.
- Sprint testing
Intervention · OTHER
The sprint training program will be performed twice per week with the first day of training focused on shorter distances to focus on acceleration and the second training day focused on maximal velocity. The relative efforts and distances for each training day will mimic a similar prescription to that of the resistance training program.
