摘要

緒論：近期國軍開發了一套完整的戰鬥個裝，目前有關穿戴此套個裝對於我國軍人在基本步態上的下肢關節角度、力矩以及肌肉活化影響尚未可知，因此需更進一步探討。方法：10名軍人為本實驗參與者，戰鬥個裝加上步槍的總重為20公斤，每一位受測者需在10公尺走道上以自選速度行走，並進行沒穿個裝以及有穿個裝的試驗。實驗使用紅外線高速攝影機、無線肌電電極和測力板收取資料，以成對樣本T檢定做統計分析。結果：有穿個裝的軍人在著地期有較大的髖、膝關節關節活動度，並且軀幹都呈現較為前傾的現象，而在力矩上，髖關節有較大屈曲以及外展力矩，膝關節有較大的伸直以及外展力矩，而踝關節有較大的蹠屈力矩。肌電方面，有穿個裝的軍人在推進前期，肌肉的活化程度較高。質心運動方面，軍人在穿著個裝會產生較大的垂直方向位移量以及動位能峰值時間差。結論：由於整體重量加上個裝中的腰帶及軍靴改變了下肢關節在步態上的活動程度，導致下肢關節的負荷增加，未來對於軍事訓練上可以多加強下肢的肌肉力量，並且在腰帶以及軍靴的佩帶議題上可加以探討。

Introduction: Recently the National Army has developed the new personal military combat suit. At present the effect of wearing that suit on soldiers is unknown. Methods: There were ten male soldiers participated in this study. The weight of whole suit is 20 kg. All groups were walk in 10m walkway which contain a force plate. 7 cameras were used to capture the three-dimensional kinematics data, four surface wireless EMG were used to capture the rectus femoris, gluteal maximus, medial gastrocnemius and erector spinae muscles activity, one force plate to capture kinetic data. Result: The test group have more hip and knee range of motion, and the trunk show more forward leaning. Flexion moment and abduction moment is significant increase in hip joint, extension moment and abduction moment is significant increase in knee joint, and plantar flexion moment in ankle is increase. On muscle activity, the test group have more muscle activity on lower limb and trunk during preswing. Lastly, the test group have more displacement of center of mass on the vertical plane and the time between potential energy and kinetic energy peak value. Conclusion: The weight of combat suit, the belt and the boots restrict the movement of lower limbs on gait. As a result, it increases the loading on the lower extremity. The improvement of the belts and boots is the problem needs to be solved in further. In order to improve the loading problem, lower extremity training is critical for the soldiers.
