Comparing Hamstring Exercises and Sprint Training for Athletes
This study is comparing different ways to train your hamstring muscles. Researchers want to see if specific eccentric hamstring exercises, like the Romanian Deadlift (RDL) or Nordic Hamstring Exercise (NHE), or a sprint-specific training program, are better at changing hamstring muscle size and improving sprint performance, strength, and power. You could be eligible if you are a healthy adult athlete between 18 and 25 years old, have experience with resistance training and team sports, and haven't had a recent hamstring injury or major lower body surgery. The study aims to find out which training method leads to the most improvement in hamstring muscle structure (like fascicle length and muscle volume) and athletic performance. The current recruitment status is unclear.
- Study design
- This interventional study plans to enroll 90 participants who will be randomly assigned to one of three training groups: RDL, NHE, or sprint training.
- What's involved
- You would undergo baseline testing, participate in a 10-week training program based on your assigned group, and repeat performance testing and imaging mid-intervention, after the intervention, and after a 2-week deloading period.
- Compensation
- Not stated in the trial record.
- Follow-up
- You will be followed for 2 weeks after the 10-week intervention period to assess changes after de-training.
