초록/요약

The purpose of this study was to evaluate the ankle joint movements and moments during Plie-Releve between wearing a toe-shoes and barefoot. These experimental subjects were 6 females, who had no skeletal muscular disease. They were performed Plie-Releve with wearing a toe-shoes and barefoot. Repeated t-test is applied to get the difference of ankle joint movements and moments significant level of each experiment is set as α=.05. 1. There were significant between wearing a toe-shoes and barefoot on plantar/dorsi flexion, internal/external rotation with range of ankle joint movement. 2. There were significant between wearing a toe-shoes and barefoot on extension inversion, internal rotation angular velocity with ankle joint. 3. There were significant between wearing a toe-shoes and barefoot on dorsi flexion and external rotation moments with ankle joint. In conclusion, when subjects perform the Plie-Releve at wearing a toe-shoes, ankle becomes more range of joint angular displacements and maximum angular velocities. In addition, these kinematics factors occurred that made an unstable ankle joint. So, ankle joint moments at wearing a toe-shoes occurs larger as well as ankle joint moments at unwearing a toe-shoes, which supports the argument that protective muscle-skeletal training of ankle joint is performing to prevent stable the ankle joint from acting ankle joint at Plie-Releve.
