Can the right work-rest rhythm and a massage gun soften stiff calf muscles?

This study looks at how different work-rest schedules during calf-raise exercises change calf muscle stiffness in volleyball athletes. Thirty players (15 women and 15 men) will do three exercise sessions with different work-rest patterns, and their calf muscle stiffness will be measured before and after exercise using a special ultrasound technique. The study also checks whether a five-minute percussive therapy session helps reduce stiffness during recovery. The goal is to see which schedule and recovery approach might best help muscles relax after exercise.
