The training effects of KOSHIWARI (SUMO squat) exercise

Abstract

The purpose of this study was to investigate the effect of KOSHIWARI, which are traditionally performed in sumo wrestling, on range of motion of hip joint, muscle strength of around hip joint, athletic ability and dynamic balance, compared to the wide stance squat (WS-SQ), which is a typical exercise for the lower limb. The exercise intervention was conducted over 8 weeks. Each of these measurements were taken prior to the exercise intervention and again at 4 and 8 weeks. The 8-week of intervention, changes in hip abduction range of motion, hip adduction and extension strength, and dynamic balance ability were noted. In particular, there was a significant difference in hip adduction strength between KOSHIWARI and WS-SQ, suggesting that KOSHIWARI may be more effective than WS-SQ for improving muscle strength of around hip joint.
