The objective of this research study was quantify the power, force of vertical impulse, jumping height and the relation of the power output during the execution of the layup in basketball, by variables associated to anthropometric data. The study was carried with seven basketball players, university students, male, from the Universidade Estadual Paulista Julio Mesquita Filho (Unesp) basketball team, from Bauru City. The players were an age of 20,7 ± 2,4 years old, body weight of 77,1 ± 9,4 kg, body fat of 14,7 ± 3,6%, lean mass of 65,5 ± 6,2 kg and height of 180,0 ± 5,0 cm. Each player did the ability of the layup three times, with a previous time to adapt. The kinetic and kinematic values was obtained from the data of a system that consists of photocells and a contact carpet from a system called JumpSystemâ (CEFISE), using after that equations of UVRM and impulse. The photocells was dispose to capture the previous run-up, as well the speedy in the time of two steps of the layup, and it was also synchronized with the contact carpet in the last step, to preserve the exactly time of the propulsion of jump. In this way, the values and the kinetic variables found was vV (2,94 ± 0,3 m's-1), vH (11,3 ± 3,4 m's-1), vI (11,8 ± 3,2 m's-1), time of contact (0,214 ± 0,2 s), angle of jump (15,9 ± 6,26 graus) and H (44,3 ± 8,9 cm). The variables and the kinematic values found was FimpV (974,9 ± 119,03 N, PP (3112,9 ± 633,9 W) and PM (1556,4 ± 316,9 W). To better understand the ability of layup in basketball, as the kinetic variables, kinematic variables and anthropometrics that determine the performance, the study did correlations between dV (H) with vV, vH, vI, angle, FimpV, PP e PM; FimpV, PP e PM com with the kinetic variables of vV, vH, vI, angle, and anthropometric variables of PC and height, and correlations of PP e PM with %G and MM. So, significant results was found between the correlations of dV with FimpV (R2 = 0,81)...
