| 中文摘要 |
本研究目的在分析96年全國運動會划船金牌選手，在划船測功儀上進行500公尺測驗。本研究對象以男女各一名划船金牌選手為受試對象，以一部JVC高速攝影機(60Hz)搜集受試者矢狀面划船動作，取得測驗結果及入水和出水階段的第100公尺、200公尺、300公尺、400公尺、500公尺的踝關節、膝關節、髖關節和肩關節角度以動學分析。結論如下： 一、在500公尺的划船速度上，男選手到最後100公尺因肌耐力不足，因此速度減少；女選手則有較佳的體能狀況，並能完成最後的衝刺。 二、入水階段男女選手膝關節角度過大，須減少膝關節的角度，並保持身體重心的平衡，才能將蹬腿的力量發揮到最大，以增加船速。 三、出水階段男女選手踝關節及膝關節須充分伸展，髖關節應避免角度過大，也就是身體軀幹後仰過多，而造成船在前進時，船身上下幅度過大，而影響船速。 |

The purpose of this study was to analyze that the rowing gold medalists in the 2007 National Athletic Games took 500-meter ergometer test. There were one male and female rowing gold medalist as subjects. The whole process was recorded by a JVC high-speed video camera (60Hz) so as to test the rowers' sagittal plane motion, get the results, and measure the angels of the ankle joints, the knee joints, the hip joints, and the shoulder joints at 100 m, 200m, 300m, 400m, and 500m in the beginning and in the end of the race. These data was analyzed by dynamics. The following were the conclusions: 1. At a 500-meter race, the speed of the male rower dropped at the last 100 meters since he didn't have enough muscular endurance to speed up; while the female racer was in such a good condition to finish it. 2. Both male and female rowers' knee joints were over bended at the beginning of the race. They needed to reduce the angles of the knee joints and balanced their bodies so as to maximize its power as the rowers extended their legs to add up the speed of boats. 3. At the end of the race, both rowers had to fully extend their ankle joints and the knee joints, avoiding overextension of the hip joints; in other words, they shouldn't lie back too much, which would make the boat move up and down and reduce its speed while going forward. |
