Brief Summary

The study aims to examine the acute effects of static and proprioceptive neuromuscular facilitation stretching exercises with blood flow restriction on hamstring flexibility, muscle strength, and single leg hop in athletes. Outcome measures were hip range of motion, isometric and eccentric hamstring muscle strength, and single leg hop distance.
