Abstract

Abstract This research is stressed at time and space characteristics (centre of gravity movements) in female pole vault. There are involved 19 female pole vault jumpers with sport performance 380 – 483 cm, divided on 2 different groups; higher and lower level from the point of sport performance. We found that in time parameters reached better results high performance level jumpers in phases hanging and lifting. It is coursed by better transmission on pole after take-off and by better work on the pole. As for the centre of gravity the jumpers of higher performance reached higher growth in all phases. The most significant difference can be seen in phase of lifting. Comparison of time and space characteristics enable to show the way for technique improvement in female pole-vault. Key words: female pole vault, rhythm of the jump, centre of gravity height
女子撑杆跳高的时空特征
摘要对女子撑杆跳高的时空特征(重心运动)进行了研究。女子撑杆跳高运动员19名,运动成绩380 ~ 483厘米,分为两组;从运动表现的角度看,有高低之分。结果表明,高性能水平跳线器在分阶段悬挂和提升时,在时间参数上达到了较好的效果。它是通过起飞后杆子上更好的传动和杆子上更好的工作来实现的。在重心方面,性能越好的跳线在各个阶段的生长都越快。最显著的差异可以在提升阶段看到。通过对女子撑杆跳时间和空间特征的比较,为女子撑杆跳技术的改进指明了方向。关键词:女子撑杆跳高,起跳节奏,重心高度
