摘要

本研究的目的在分析我國優秀划船選手在測功儀上進行五百公尺划船測驗，於入水及出水階段關節動作範圍之運動學分析。本研究以輔大划船隊男女各一位優秀划船選手為受試對象，以一部JVC攝影機(60Hz)蒐集受試者矢狀面划船動作之入水及出水時的第十槳、第二十槳、第三十槳、第四十槳、第五十槳的踝關節、膝關節、髖關節、肩關節、肘關節角度進行分析，找出男女划船選手動作範圍。結果發現：男生入水各關節角度為踝關節63.49±3.61度，膝關節59.67±3.65度，髖關節20.47±5.03度，肩關節94.46±1.27度與肘關節157.60±4.21度；男生出水各關節角度為踝關節100.62±1.73度，膝關節157.01±3.68度，髖關節124.76±4.65度，肩關節41.43±4.20度與肘關節53.79±4.28度；女生入水各關節角度為踝關節45.62±2.65度，膝關節44.19±2.36度；髖關節30.21±1.34度；肩關節93.13±4.23度與肘關節165.31±3.44度；女生出水各關節角度為踝關節111.15±2.80度，膝關節166.58±1.28度，髖關節140.96±3.31度，肩關節44.50±4.62度與肘關節51.69±3.71度。本文結論是出水階段時踝關節要充分伸展，才能提升輸出功率及防止軀幹過度後仰，才能維持最快船速。本文建議教練應該先讓初學者在測功儀上做划船動作的練習，保持划船入水及出水階段的關節角度，以提升划船之運動表現。

The purpose of this study was to analyze the range of joint motion of 500 meters in Concept 2 rowing ergometer on Kinematics, during the phase of enter and surface water, one male and one female elite rower were used to be the subjects. JVC video camera (60Hz) was the major equipment to collect the data from sagittal plane of subjects. The ankle joint, knee joint, hip joint, shoulder joint, elbow joint angle of the 10th oar, the 20th oar, the 30th oar, the 30th oar, the 40th oar, and the 50th oar while entering and surfacing water were be analyzed to decide the range of motion for male and female rowing players, according to the displacement of the center of mass. After data calculating and data analyzing, the following conclusions of this study have been reached: 1. The joint angle for men player to enter water were 63.49±3.61 degrees of ankle joints, 59.67±3.65 degrees of knee joints, 20.47±5.03 degrees of hip joints, 94.46l.27degrees of shoulder joints and 157.60±4.21 degrees of elbow joints. 2. The joint angle for men player to surface water were 100.62±1.73 degrees of ankle joints, 157.01±3.68 degrees of knee joints, 124.76±4.65 degrees of hip joints, 41.43±4.20 degrees of shoulder joints and 53.79±4.28 degrees of elbow joints. 3 The joint angle for women player to enter water were 45.62±2.65 degrees of ankle joints, 44.19±2.36 degrees of knee joints, 30.21±1.34 degrees of hip joints, 93.13±4.23 degrees of shoulder joints and 165.31±3.44 degrees of elbow joints. 4. The joint angle for women player to surface water were 111.15±2.80 degrees of ankle joints, 166.58±1.28 degrees of knee joints, 140.96±3.31 degrees of hip joints, 44.50±4.62 degrees of shoulder joints and 51.69±3.71 degrees of elbow joints. The conclusion of this study were following: 1. At surface at stage, the ankle joint should be more extended in order to prevent the excessive backward of trunk. 2. It was necessary to maintain the stable joint angles in high oar frequency to improve rowing performance.
