蹼泳不同出發動作動力學分析

The Kinetic Analysis of Different Start Movemrnt for Fin Swimmers

摘要


本研究目的主要探討足弓式與全腳掌兩種不同出發動作之動力學參數,分析兩者在參數上之差異。研究對象為5名優秀青少年蹼泳選手,藉由高速攝影機(120hz)獲取選手15公尺衝刺時間;測力板(1200hz)擷取受試者在兩種不同出發方式之動力學參數,以相依樣本t檢定,比較兩者之差異。研究結果發現:在出發15公尺的衝刺上,足弓式的出發快於全腳掌式;在動力學參數部份,水平作用力在足弓式較大,可以幫助受試者在出發時獲得較大的水平速度。

The purpose of this study was to compare the kinetic parameters of two different starting drives stand postures of elite fin swimming athletes. The subjects are five elite fin swimmers. This study employed two different equipment: high speed digital video camera (Casio EX-ZR100, 120Hz) and three-dimens -ional force plate (Kistler 9260AA6, 1200Hz). The t-test (α=.05) was used to test the differences of two start movements. Ultimately, the results showed the arch of foot standing posture and the sole of foot standing posture were significant differences in 15 meters time and the peak of horizontal force. In short, we can conclude that the arch standing posture are better than whole foot posture.
