Abstract

BACKGROUND

Approach speed is a major determinant of pole-vault performance. Athletic jump events such as long jump, triple jump, and pole vault can utilize an elevated track for the runway. Feedback from athletes indicates a benefit of using an elevated track on their results. However, there is no evidence that elevated tracks increase athletes' performance.

PURPOSE

To investigate the potential advantage of using an elevated track during elite pole-vault competitions on run-up speed parameters.

METHODS

Performance and run-up criteria (speed, stride rate, contact, and aerial time) were measured from 20 high-level male pole-vaulters during official competitions on either a regular or an elevated track. Parameters comparisons were made between both conditions, and run-up parameters were confronted to speed modification on the elevated track.

RESULTS

Statistical analyses indicated that for the elevated track, there was a small improvement in final speed (1.1%), stride rate (1.1%), and takeoff distance (3.1%) and a small reduction in aerial time (-1.9%). The study highlighted different individual responses depending on athletes' capabilities. The authors noted that speed improvement was largely correlated with stride-rate improvement (r = .61) and contact-time reduction (r = -.51) for slower athletes.

CONCLUSIONS

Elevated tracks can increase final approach speed in pole vault and positively influence performance. Interindividual responses were observed in these findings.

摘要

背景

助跑速度是撑杆跳表现的主要决定因素。田径跳跃项目,如跳远、三级跳远和撑杆跳,可以利用高架跑道。运动员的反馈表明,使用高架跑道对他们的成绩有好处。然而,没有证据表明高架跑道能提高运动员的成绩。

目的

研究在精英撑杆跳比赛中使用高架跑道对助跑速度参数的潜在优势。

方法

在正式比赛中,对 20 名高水平男性撑杆跳运动员的表现和助跑标准(速度、步频、接触和腾空时间)进行了测量,他们分别在常规跑道和高架跑道上进行比赛。对两种条件下的参数进行了比较,并将助跑参数与高架跑道上的速度修正进行了对比。

结果

统计分析表明,对于高架跑道,最终速度(1.1%)、步频(1.1%)和起跳距离(3.1%)略有提高,腾空时间(-1.9%)略有减少。研究结果表明,根据运动员的能力,存在不同的个体反应。作者注意到,对于速度较慢的运动员,速度的提高与步频的提高(r=0.61)和触地时间的减少(r=-0.51)密切相关。

结论

高架跑道可以提高撑杆跳的最终助跑速度,并对成绩产生积极影响。在这些发现中观察到了个体间的反应。
