Interventions/Control_1
Volleyball players in the functional training group participated in an eight-week hopping program, consisting of three 40-minute sessions per week. Each session included a 5-minute warm-up, 30 minutes of six plyometric hopping exercises, and a 5-minute cool-down. Exercise intensity was progressively increased by adding new exercises, sets, or repetitions. Rest periods were 30 seconds between sets and 1 minute between exercises. All sessions were supervised by a corrective exercise specialist and sports medicine physician, with ongoing feedback for posture control and injury prevention.
Interventions/Control_2
The control group continued their normal daily activities without any additional training.
