Four males (age: 26.8 ± 3.3 years, height: 162 ± 5 cm, weight: 58.8 ± 5.8 kg) and four females (age: 21.5 ± 1.8 years, height: 162 ± 4 cm, weight: 61.3 ± 6.5 kg) who are national powerlifting athletes were recruited in this study. Each subject was asked to perform the deadlift in the motion laboratory with 30%, 50%, 70%, and 90% of his/her peak performance of deadlift. The VICON 612 motion analysis system was used to record the trajectories of reflective markers that were placed on the skin surface of spinal landmark. The information of landmarks of spine was used to calculate the displacements and the curvature angles of the spine. Repeated measures one-way ANVOA and Duncan post hoc tests were used to test the statistical differences for kinematical parameters with the alpha level .05. The results showed that the displacements of the 7th cervical spine (C7) and the 6th thoracic spine (T6) in the loading of 90% of the peak performance of deadlift and the inclination of trunk in saggittal plane were significantly greater than that in 30% and 50% of loading of the peak performance during the stage of prior-movement. The results of Kyphosis angle showed that the range of motion in the loading of 90% of the peak performance was significantly greater than that in the loading of 30% and 50% of the peak performance during the stage of prior-movement, the stage of movement, and the total stage of movement. It indicated that the powerlifting athletes increased the displacement of trunk and the angle of kyphosis posteriorly during the stage of prior-movement for the treatment of increase loading. Under the situation of larger loading, the powerlifting athletes adopted the strategy of pre-acted upper trunk and held the angle of kyphosis to perform the movement of deadlift.目　次 第壹章　緒論…………………………………………………………1 　第一節　問題背景…………………………………………………1 　第二節　研究目的…………………………………………………4 　第三節　研究範圍與限制…………………………………………4 　第四節　名詞解釋與操作性定義…………………………………5 　第五節　研究的重要性……………………………………………7 第貳章　文獻探討……………………………………………………8 　第一節　健力運動…………………………………………………8 　第二節　重物搬運對脊柱的影響…………………………………15 　第三節　脊柱形變的測量相關研究………………………………23 　第四節　本章總結…………………………………………………25 第參章　研究方法與步驟……………………………………………27 　第一節　實驗參加者………………………………………………27 　第二節　實驗時間與地點…………………………………………28 　第三節　實驗儀器與設備…………………………………………28 　第四節　實驗步驟…………………………………………………31 　第五節　資料的收集與處理方法…………………………………32 　第六節　統計方法…………………………………………………32 第肆章　結果與討論…………………………………………………33 　第一節　脊柱標記點的運動特徵…………………………………33 　第二節　軀幹的角運動特徵………………………………………44 　第三節　不同負荷的運動比較……………………………………54 　第四節　綜合討論…………………………………………………66 第伍章　結論與建議…………………………………………………72 　第一節　結論………………………………………………………72 　第二節　建議………………………………………………………73 引用文獻 一、中文部分…………………………………………………………74 二、英文部分…………………………………………………………76729338 bytesapplication/pdf運動學;脊柱;硬舉;健力kinematics;spine;deadlift;powerliftingthesis
