F-ESWT

F-EWST with 0.15 mJ/mm2 intensity and 6 Hz frequency for 3 weeks. The shocking head was placed at the muscle positions of the long head of the bicep femoris, semitendinosus, and semimembranosus for 1,000, 500, and 500 shocks, respectively, accounting for 2,000 shocks in total/ session/week.

Group Type EXPERIMENTAL
