It is a transversal and analytical study, whose objective was to evaluate the palmar grip strength in jiu-jitsu athletes in competitive level, with the purpose of establishing a functionality range for this population, considering that the number of athletes has been increasing. The subjects of the research were 100 individuals from the masculine gender divided in two groups (CG and GA) with age between 20 and 30 years. The group of athletes (GA) had 50 subjects and the control group (CG) had 50 subjects. The instrumental used in the study was the dynamometer JAMAR  . Regarding the average of the prehension strength recorded in the study groups, there was a significant predominance (p<0,05) in the GA in comparison to the GC only for the left hand. In the first group, there was a trend of a increasing the strength as the measurement were taken, while in the second one, this trend was reverted. We concluded that jiu-jitsu athletes do not present high values of palmar grip strength, being that the jiu-jitsu practice suggests that occur physiological causes alterations characterized by the increase of the ability of resistance in the movement of prehension. The results obtained must be considered as an indication of strength for rehabilitating the manual function of the Jiu-Jitsu athlete.Keywords - Leadership, soccer, coaching. abstract - Jiu-jitsu, palmar grip strength, evaluation, dynamometer.
