||The purpose of this study was to examine the power-strength curve in a half squat exercise in trained basketball players of the EBA league. For that, a cross sectional, descriptive study was carried out to 8 high-level male basketball players. After controlling the participants 1RM, a progressive test, consisted on moving loads of 30, 45, 60, 70 and 80% of 1RM as fast as possible in the concentric phase, was performed. The participants showed the highest peak power output with loads of 45% of 1RM. These results differ from the wide literature, which shows values ranged between 30% and 70% of 1RM; this can be due to: a) the analyzed sample; b) the experience of the participants; and c) the methodology used for the record. Therefore, we concluded that, the basketball players studied present values of peak power output, in competitive period, near to 45% of 1RM in the half squat exercise.
