등척성 체간 운동이 젊은 성인의 근지구력과 균형능력에 미치는 영향

Abstract

This study aims to identify the effects of an isometric trunk exercise program on muscle endurance and balance ability in young adults. Fourteen young adults volunteered to participate in this study. Isometric muscle endurance tests (trunk curl in supine, hyperextension of trunk in prone, and arm-supporting side bridge) and one-leg standing test were used to measure muscle endurance and balance of subjects. Isometric trunk exercises were performed for 30 minutes, twice per week for 6 weeks (a total of 12 sessions), including upper and lower abdominal drawing, abdominal bracing, posterior pelvic tilting, supine bridge exercise, and alternating raising of limbs in quadruped position. After the intervention, significant improvements were found for all items of muscle endurance and balance (p<.05). These findings suggest that an isometric trunk exercise program might be favorably used to enhance muscle endurance if the trunk and balance in young adults. Further studies need to support our findings.
