摘要

本研究僅針對國內十二名選手在正式比賽時所表現的「特卡切夫」為研究對象，以一部攝影機做二度空間動作分析，將人體分成七個人體肢段（rigid segments），計算有關運動學之各變數與角動量。其研究動機在於探討國內選手在單槓實施「特卡切夫」時之動作持徵，與建立國內選手在單槓「特卡切夫」動作上之基礎資料庫。研究結果如下：
一、 最後一圈大迴環從倒立開始的型態有三種（一）倒立型態；（二）背弓型態；（三）屈腹型態，但不論那一種型態在大迴環下擺到急振前，都會有先屈腹在伸展的技巧。
二、 大迴環的動作型態與振浪技巧並無絕對關聯，與各人的動作習慣較有關係。
三、 一個好的特卡切夫騰越動作，除了離槓後身體的飛行高度外，更重要的是再抓槓瞬間身體的高度，以及身體與單槓間的距離，是否有利於下一個動作的延續。
四、 表現質佳的特卡切夫騰越動作，因首重於離槓前的反弓身制動腿技術，與騰空後上半身迅速直立、下半身快速擺越準備抓槓的技術。

In this study, 12 gymnasts’ performance was filmed at 60 frames per second during horizontal bar competition A two dimension analyzing system was realized by using a camera. In order to calculate the kinetic variables, the gymnasts are represented as linked rigid bodies (segment menthol). The native of this study was to discuss the charter of the Takatchov and to build the database for the Tkatchov. This study results as the follows:
1. Three techniques were used to maintain a vertical position when the gymnast passed the area over the bar in the last giant swing before release. The first one was the after he raised his arms stretched and kept his hip angle almost 180 degree. It was likely handstand on the high bar. Second techniques was that he kept his hip angle at between 150 and 160 degrees. However, the characteristic of giant swing was that during the downswing, a gymnast obviously decreased the hip angle and then rapidly extended the hip angle.
2. There was no significant correlation between the beat action styles and giant swing in downswing from above bar.
3. A good quality technique of must have a flight high after release, height of regrasp, and the body of distance from the bar.
4. When the gravity of body pass the bottom of the giant during the upswing, the shoulder extened followed by shoulder and hip angle flexion and rapid extension just prior to the release of the bar. After release, upperbody rapid stand up and lowerbody fast pass backward to prepare to catch bar that it is most important.
