Loaded Plyometrics and Short Sprints with Change-of-Direction Training Enhance Jumping, Sprinting, Agility, and Balance Performance of Male Soccer Players

This project investigated effects of 8 weeks biweekly loaded combined plyometric and short sprint with change-of-direction training an in-season regimen young soccer players. An experimental (n = 17, age: 16.5 ± 0.5 years, body mass: 64.5 5.2 kg, height: 1.73 0.07 m,) control group 16.7 65.6 4.8 1.74 m) were tested pre- post-intervention for squat-jump (SJ), countermovement-jump (CMJ), five-jump test (5JT), 10 m 30 performance, ability, dynamic balance performance. The (EG) outperformed the (CG) over in jumping (p < 0.001; d 0.98–1.17), sprinting 0.94), ability 1.24), performance 0.53–0.74). We conclude that adding sprints to habitual improves athleticism Therefore, should be implemented as a part research-informed training.
