RESUMO

The purpose of this study was to evaluate the parameters of the isometric handgrip strength curves in highly trained judo athletes from different categories. 44 judo athletes who were participating of the VII Troféu Brasil, which took place in Porto Alegre, RS and 25 Physical Education students participated of this study. The handgrip strength was evaluated using a dynamometer built at LABIN, located on CEFID/UDESC. The evaluation of the judo athletes was performed during the championship weighing, in Porto Alegre, and the evaluation of the students was performed at LABIN. The handgrip strength was evaluated for 10 seconds, with one attempt on the dominant hand and one attempt on the non dominant hand, on the seated position adapted from the ASHT. The parameters evaluated were Maximum force (FMAX), Time to maximum force (T100), impulse to maximum force (imp100), rate of decrease (IQ) and impulse (imparea1). For the analysis regarding the athletes, the individuals were divided into three groups, according to their body mass (MC), into two groups according to their results and into two groups according to T100. To eliminate the influence of MC over the strength values recorded on both tests and allow the comparison between individuals of different categories and consequently of different body sizes, the allometric scaling was performed on the FMAX. After the statistical analysis was conducted, differences between the lighter and heavier categories in the handgrip strength curve parameters were found. In this case, the correction of the strength values by the corrected MC eliminated the influence of the MC for the categories. Concerning the result of the competition, relative values highlighted the differences between the groups. It is suggested that further studies are conducted, investigating the handgrip strength in judo athletes, for a better understanding of the differences between he categories and a closer investigation to the sport.
