我國撐竿跳高選手助跑與起跳動作之運動學比較分析

Kinmatic Analysis for Pole Vaulters' Carry-and-Approach, and Take-off in Taiwan

摘要


本研究主要目的在探討我國撐竿跳高選手持竿助跑與起跳動作之運動學比較分析。研究對象是以兩位優秀撐竿跳高選手的持竿助跑及起跳階段動作,進行最佳成績運動學分析。經研究分析的結果得到以下結論: 一、從重心軌跡的曲線圖可以發現A選手的起伏比B選手來得大,這個速度慢、起伏大即是影響最後助跑的水平速度與起跳插穴動作的連貫性與凖確性。 二、國內優秀撐竿跳高選手的水平速度6.29公尺/秒較之世界一流選手7.70~9.00公尺/秒為慢。因此,如能增強水平速度必能提昇國內撐竿跳高的成績表現。 三、國內優秀撐竿跳高選手之起跳角度平均為18.91度與世界一流選手的14-24.5度有相同之處,對於起跳角度達到一流水凖是值得給予肯定的;若加強選手的起跳速度與起跳復垂直速度便能突破停滯已久的成績。

The main purpose of this research is to explore the data on technical analysis for pole vaulters, carry-and-approach, and rake-off Objectives for the top-score kinetice analysis ate these two excellent pole vaulters. After analyzing then movements of carry-and-approach and take off, it follows the conclusion as below 1 .Vaulters A's center of gravity undulates with slower speed than vaulter B's in its Locus; besides, the curve of the locus also shows that vaolter A has larger undulation. The slowness in speed and great scale of undulation are the direct Proofs that affect the score of A pole vaulter, s performance. 2 Vaulters, horizontal velocity 6 29m/s in this study is found slower than 7.79~900m/s the world excellent pole vaulters. It must be taken that enhancing national pole vaulters' horizontal velocity to improve then performance. 3 The average take-off velocity in this research is 18.91, which is quite the same with other world-famous players' averaging statistic, 14-24.5, according to statistics. We should give positive recognition to this achievement, Therefore enspeeding pole vaulters' take-off velocity and their vertical speed after take-off will be able to improve their performance.
