*Denotes significant differences from the corresponding pre and CON group values (p < 0.05). b: small, c: moderate, d: large, and e: very large ES. CMVJ: countermovement vertical jump, COD: change of direction, Yo-Yo IR 1: Yo-Yo intermittent recovery level 1, MKD: maximal kicking distance, m = meter.
