Characteristics of Handgrip (Kumi-Kata) Profile of Georgian Elite Judo Athletes

Abstract

The study investigated the characteristics of kumi-kata in elite judokas on kinematic and temporal parameters of different types of handgrip (HG). Methods: fourteen participated in this study male athletes (23.5±2.61 years; 1.81±0.37 0 m; 87.25±22.75 kg), members of the Georgian Judo team. To characterize the dominance and types of kumi-kata were analysed, and to characterize kinematic and temporal parameters and handgrip. Results: The values of 0.26±0.69s and 0.31±0.03s for reaction time were obtained, respectively, in the full grip and pinch grip; 19.62±18.83N/cm/s and 6.17±3.48N/cm/s for the rate of force development; 475,21 ± 101,322 and 494,65±112,73 and FDR 1,45 ± 0,824s for the time between the force onset to the TFP; and 41,27±4,54N/cm/s. There was no significant
difference variable, except for the dominance of kumi-kata (p<0.05) used in combat. Conclusion: The dominance kumi-kata is a technical option, as it does not depend on the kinetic-temporal parameters of handgrip.
