Abstract

The aim of this study was to compare the handgrip strength, flexibility level (sit and reach test), kumikata and biomechanical aspects of the uchimata technique of two national level judokas, one who favors to use the uchimata (tokui-waza), and one who selects another judo technique in combat. We recorded the highest value of three attempts for handgrip strength (handgrip test), and flexibility (sit and reach); we recorded the highest value of three attempts for strength (handgrip test) and flexibility (sit and reach test); we analyzed the uchimata phases (kuzushi, tsukuri, kake and zanshi) in 3D using Vicon® system. We found that non-traditional kumikata during combat (grips with both hands on the same side), greater level of flexibility (45 vs. 36 cm), greater leg opening distance (113 vs. 66 cm) and greater displacement speed of the center of mass performing the technique (75 vs. 49 cm/s) may be indicators for the choice of uchimata technique as tokui-waza.
