摘要

撐竿跳高中持竿助跑和起跳為撐竿跳高最重要的技術也是影響成績最主要的因素，因此本研究主要目的是以國內外優秀選手技術比較，從中找出差異，進而提供國內教練及選手參考。研究對象是以參加九十一年全國田徑錦標賽男子撐竿跳高前四名為受試者，在比賽中用JVC高速攝影機拍攝持竿助跑最後三步和起跳動作，再以APAS 三度空間動作分析軟體，將資料轉換為二度空間之運動學資料，經研究分析結果得以下結論：一、國內優秀選手助跑最後三步水平速度較世界級選手慢且損失大，使得起跳水平速度有1.11 m/s的差距，若能提升選手徒手的絕對速度及助跑的節奏，應能有效的增加起跳水平速度，進而增進國內撐竿跳高的成績表現。二、國內優秀選手起跳點位於上手握竿垂直線前方3.8公分，將會造成選手在起跳腳還未推蹬完全時，即竿子已接觸到插竿箱的底部，迫使起跳水平速度的損失。

Approach and take off are the most important techniques in pole vaulting and also the major factors which affect the score. Therefore, this study was to analyze the approach and take off techniques of top International and domestic athletes to find out the differences for our coaches and athletes. The research subjects are 4 top athletes of 2002 National Track and Field competition during the contest. The approach and take off were recorded by two JVC high speed cameras, then analyzed by APAS three-dimensional movement software and then the data were transmitted to two-dimension kinematics data. 1.The approach speed of top domestic athletes were significantly different compared to that of top international athletes. If the speed and rhythm can be improved, the performance will surely be enhanced. 2.The take off point of domestic top athletes was over the vertical line of the up hand grasping point and the ground. It made the pole touch the planting box too early and lost the horizontal speed.
