The effect of functional training on the explosive power of Greco-Roman wrestlers

This study investigates the effects of functional training on the development of explosive power in Greco-Roman wrestlers. The research involved 20 male athletes aged 18–25, divided into two groups: an experimental group (EG) and a control group (CG). The EG followed an 8-week training program incorporating plyometric exercises, weightlifting exercises (snatch, clean & jerk, speed squats), and isometric holds, while the CG continued their standard training routine without a specific focus on explosive power development. Pre- and post-training assessments included the countermovement jump (CMJ) test, medicine ball throw, force plate measurements, and dynamometry. The results revealed significant improvements in the EG: CMJ height increased by 12.5%, maximal push-off force by 11.6%, and ground contact time decreased by 18.2%. The medicine ball throw distance improved by 13.9%, and grip strength increased by 11.2%. In contrast, the CG exhibited minor improvements ranging from 3.8% to 5.1%. A correlation analysis demonstrated a strong relationship between lower-limb explosive power, maximal push-off force, upper-body strength, and grip strength (r > 0.90, p < 0.001). These findings confirm that explosive strength is a key determinant of performance in Greco-Roman wrestling. The study aligns with previous research, highlighting the benefits of combining plyometric and weightlifting exercises to enhance speed-strength characteristics in combat sports athletes. The practical significance lies in the application of these training methods to improve wrestlers' explosive power, providing a competitive advantage in high-performance wrestling.
