中文摘要 | 游泳訓練的方向不應只是以選手比賽的成績及教練的感覺來訂定,事實上分析選手比賽時的划頻、划幅、速度、效率將更能了解到選手的個別差異及確立正確的訓練方向,本研究利用高速攝影機、攝下8名參加東亞運女子50公尺自由選拔選手比賽的全程,配合Peak Performance分析選手50公尺分段的划頻、划幅、速度、效率,並將所得資料經統計處理。經攝影機60Hz計算所得成績和大會電動計時器(亞米茄OSM6)所得成績,其正確率達99.9% (p<.01)。游泳競賽中划幅對速度的相關達顯著(r=.921、p<.05)。划頻和速度呈現負相關(r=-.952)。台灣組在分段距離與各變項的相關測試方面,除了划頻呈現正相關外(r=.998),划幅(r=-.921)、速度(r=-.962)、效率(r=.923)皆呈現顯著負相關,可看出台灣組選手,以增加划頻、降低划幅來當作加速度的比賽方式,會造成速度及效率的下降。反觀奧運組選手以維持划頻、增加划幅的競賽策略卻能有效的提升游泳速度及效率。關於這點,應值得所有從事游泳訓練工作的伙伴加以思考。 |
英文摘要 | The principle of swimming training should not be making up by athlete's score and coach's personal feeling. In fact, analyzing athlete's stroke rate stroke length velocity and efficiency will help detect athlete's individual difference and confirm the correct training direction. This case study is based on the complete process of 8 athlete's the female's 50-m freestyle in East Asian Games Trial. The data of stroke rate stroke length velocity and efficiency for 50-m sections of each athlete were processed by peak performance analysis. The results as following: Comparing the scores which taking up by the 60Hz Video camera with the electrical timer (OMEGA OSM6); is almost up to perfect positive correlation (r=.99, p<.01). Stroke length has positive correlation with velocity (r=.921, p<.0l), stroke rate has negative correlation. The segment score has negative correlation with stroke length(r=-.921) velocity(r=-.962) efficiency(r=-.923) beside stroke rate(r=-.998). Taiwan group using the tactics of increasing stroke rate & decreasing stroke length would decrease the velocity and efficiency. In other words, Olympic group using the tactics of keeping stroke rate and increasing stroke length can increase velocity and efficiency. |
