摘要

本研究旨在探討長期瑜珈訓練的中年女性，其平衡感與同年齡層無規律運動習慣女性的差別。研究對象以12名年齡為40到60歲其從事哈達瑜珈運動五年以上；控制組則為12名同年齡層，但平常無固定運動習慣。以Biodex Balance System SD平衡評估儀，測試張眼、閉眼情境下，雙腳站和單腳站在靜、動態的姿勢穩定度。結果發現，長期練習瑜珈組，其雙腳站在開眼等級12的整體穩定指數、內外穩定指數、閉眼等級12的整體穩定指數、前後穩定指數、及閉眼等級10的整體穩定指數；慣用腳單腳站在閉眼靜態的整體穩定指數、內外穩定指數、閉眼等級12的整體穩定指數、前後穩定指數、及開眼等級10的整體穩定指數，比起無規律運動控制組，擁有較好的姿勢穩定度。故推測長期練習瑜珈者有較好的姿勢控制能力，若持續練習瑜珈到老年，應可減少跌倒風險。

This study aimed to compare balance ability of middle-aged females with and without long-term yoga practice. The yoga group contained 12 females with more than 5 years of yoga experience. Subjects in the control group are around the same age of the yoga group but have no regular exercise habits. We measured the sway index with Biodex Balance System SD under different conditions including bilateral, dominant, and non-dominant single leg stance with eyes-open and eyes-closed conditions. The participants tried to maintain postural stability on either a static or dynamic surface. The bilateral stance results showed that there were significant differences in OSI, MLSI score between yoga and control groups at Level 12 in the eyes-open condition, and the OSI, APSI scores at level 12 & the OSI score at level 10 in the eyes-closed condition. The dominant-leg stance results showed that there were significant differences in OSI, MLSI scores between the yoga and control groups at static, OSI, APSI scores at level 12 in the eyes-closed condition, and OSI score at level 10 in the eye-open condition. It was concluded that long-term Yoga practice can result in better postural stability. The results of reducing risks in falls may also be applied to older seniors with regular yoga practice.
