COMPARISON BETWEEN KNEE-FLEXED AND KNEE-EXTENDED STYLES IN THE MAJOR OUTER LEG SWEEP

Abstract

The aim of this study was to compare the knee-flexed technique with the traditional kneeextended technique of Osoto-gari to determine which is the more efficient and powerful. The 12 participants were randomly divided into knee-flexed and knee-extended groups. Video analysis (60 Hz) of three trials per participant revealed significant differences (p _ 0.05) in the maximum angle of legs, the body angle, and the force of sweep (Figure 1) between the knee-flexed and knee-extended groups. No significant differences were found in the movement time of Tsukuri (leg raising), kake (performing the whole movement) and the force of hands between knee-flexed and knee-extended groups.
