The sample was composed for 45 volleyball players of the man sex. The participants were submitted the anthropometrical measures (stature, body weight, percentage of fat, fat mass, lean body mass, and thigh muscle area), and vertical jump tests (squat jump, countermovement jump,, and continuous jumps 5s) at three moments: in the beginning and the end of the pre-season; in the beginning and the end of the season, being the measures made in carpet of contact Jump Test. Higher performances of the after-pubescent than pubescent were observed. Maturity, corporal mass and muscular area of the thigh had contributed significantly, but with different contributions for variation of the performance of the strength production, explaining about 5-14% of the variance (p<0,05). In pubescent significant changes in the annual cycle in the variable of the performance of ES and EES had been observed presenting increases, however, the changes had not been significant in the REES, even if showed increases the performance. The after pubescent showed significant increases in performances the ES, EES, and.
