輕艇競速加拿大式划槳動作之生物力學分析：水上與輕艇測功儀之比較

輕艇競速是一項水上運動，加拿大式艇採用單腳高跪姿，利用單槳葉的槳，以單側划槳方式划艇前進，動作技術的難度相當高，然而有關加拿大式划槳動作研究卻是相當缺乏。本研究目的在於探討輕艇加拿大式划槳的肢體動作表現之特徵以及影響輕艇速度的關鍵運動學參數，並比較水上輕艇與輕艇測功儀划槳的肢體動作之差異。以12名輕艇競速加拿大式男性運動員為研究對象，本研究包含兩部分的實驗，第一部份是水上輕艇100公尺划槳測驗，第二部份是輕艇測功儀30秒划槳測驗。藉由使用高速攝影機和動作分析系統來瞭解輕艇競速加拿大式划槳的肢體動作之特徵以及水上與輕艇測功儀划槳動作之差異。研究結果顯示，在划槳過程中肩關節和肩膀旋轉動作的活動範圍較大，而軀幹左右傾斜和骨盆旋轉的活動範圍較小。比較水上與輕艇測功儀划槳動作顯示，在肘關節、軀幹前後傾斜、軀幹左右傾斜和支撐腿膝關節的活動範圍達顯著差異。整體而言，水上輕艇與輕艇測功儀的划槳動作是有所不同的。

Canoe sprint is an on-water sport. Canoeing is kneeling on one knee, and uses a single-bladed flat paddle. Only few studies focused on the biomechanical analysis during canoe stroke in canoe sprint. The purpose of this study was to investigate the motion characteristic of the canoe stroke, examined the relationship between canoe velocity and the kinematic parameters of the canoe stroke, and comparison of on-water and canoe ergometer. The subjects were twelve male canoe sprint players. There were two tests in this study. The first one is the on-water 100 meters sprint test and the second test is the canoe ergometer 30s sprint test. All information will be gathered from high speed camera shooting and the motion analysis system to understand the motion characteristic of the canoe stroke. The results showed that the shoulder joint and the shoulder rotation had a greater range of motion, but the trunk tilt sideways and the pelvis rotation range of motion was smaller in canoe stroke. Comparison of the on-water and the canoe ergometer shows, the elbow joint, the trunk tilt forward, the trunk tilt sideways, and the support leg knee range of motion had significant differences. In conclusion, the on-water and the canoe ergometer were different in canoe stroke motion.
