拔河不同啟動姿勢與動作型態之研究

Abstract

本研究之目的是透過探討拔河隊隊員以不同啟動姿勢來完成各種動作型態之動作時間之差異情形，以了解何種姿勢來完成何種動作型態會有較佳的團隊表現。受試者為長時間受過訓練之國小八人制拔河隊之隊員。實驗方法是以高速攝影機及測力板進行同步拍攝，並利用Bio-Ware系統蒐集每名隊員從啟動姿勢（開放式、閉鎖式預備站姿）到完成高姿、中姿、低姿之動作時間及力量值，然後將所得資料以Excel軟體統計分析，所得結果如下： 一、 啟動姿勢採開放式預備站姿來完成低姿動作有較佳的團隊表現。 二、 啟動姿勢採閉鎖式預備站姿來完成高姿動作有較佳的團隊表現。 三、 啟動姿勢採開放式預備站姿時，完成動作型態的時間愈長，團隊的表現就愈佳。 四、 啟動姿勢採閉鎖式預備站姿時，完成動作型態的時間愈短，團隊的表現會愈佳。

The purpose of this thesis is to, by way of an exploration of how Tug-of-war members differ in their movement time because they use different start postures to achieve various movement patterns，understand what start posture employed to achieve a movement pattern will result in better team performance. The testers are students in an eight-member tug of war in elementary school . The experimenting method is the synchronized recording with a PEAK PERFORMANCE high speed camera and KISTLER force plate, gathering the information of the movement time of each member , from the start posture , either open standing or closed one , to the completion of high ,middle and low postures. The data is therefore analyzed with Excel system. The results are as follows: 1. The start posture of an open standing posture to complete a low posture movement results in better team performance. 2. The start posture of an closed standing posture to complete a high posture movement leads to better team performance. 3. The longer the time is in completing a movement time when taking a start posture with an open standing posture , the better the team performance will be. 4. The shorter the time is in completing a movement time when taking a start posture with a closed standing posture , the better the team performance will be.
