The study was performed on a sample of 12 male volleyball players (Category: Under 20). Data were collected in two periods (September and October), subjecting the players to intensive technical and physical work. At the beginning of the training period anthropometrics data (weight, height, BMI, reach to one hand) and the values at the vertec jump test were collected. Each player carried out 90 float services (3 series of 30 float serves, respectively to specific areas of the opponent's field 1-6-5) to check out if there is continuity of precision towards the three zones or if there is a significant difference. The results show, after four weeks of intensive training, an improvement in jumping ability at the Vertec test. It is hypothesized a not significant difference in the performance by the group of players, in terms of precision, towards the three opposing areas and a positive difference in pre-training (September) and post-training (October) performances. The monitoring of the training process will allow to estimate the effects induced through the use of physical and motor tests, allowing the coaches to design and choose the methodology and the appropriate training load, for an effective performance.
