力量素质是跳远运动员的身体素质之中最基础,也是最重要的素质之一,所有的跳远运动员都要进行力量训练。但是,教练员时常会遇到这样的情况：运动员的力量提高了,但跳远成绩却并没有提高。其原因很可能是因为力量训练的方法和手段没有充分结合跳远的专项特点。本文就跳远运动员的专项力量训练进行探讨。 相似文献

本研究根据跳远项目的专项特点，设计研制一种能够模拟不同助跑速度，反映跳远运动员起跳过程中，起跳腿专项力量训练和专项能力测试的设备。通过对优秀跳远运动员在不同控制速度下(6m／s、7m／s、8m／s、9m／s；9人，72人次)和全程助跑跳远(9人)起跳测试结果的生物力学分析，得到以下主要结论：起跳过程中，随控制速度的增加，表现出起跳腿各关节肌群的工作能力增大，起跳腿髋、膝、踝关节肌群表现出较长的伸肌力矩时相和较大的伸肌力矩值；起跳腿各关节肌群快速离心收缩、向心收缩及离心与向心收缩的转换能力对起跳起着十分重要的作用。本研究的研制设备，能够针对不同水平(不同助跑速度)跳远运动员进行起跳腿专项能力测试与评定，并可成为跳远运动员专项力量训练的有效手段。 相似文献

不同水平跳远运动员踏跳过程的生物力学分析 总被引：1，自引：0，他引：1
采用三维测力台实验方法对急行跳远踏跳过程测试,对健将,一级和二级跳远运动员踏跳中三维方向的踏跳力学特征进行探讨。从结果上分析认为：踏跳过程中起跳腿垂直方向波·谷力值和蹬伸力值虽然对跳远成绩影响较大,但运动员从缓冲到蹬伸阶段达到垂直冲量值最大值的时间长短是衡量运动员技术水平和成绩的另一重要指标,踏跳动作的实质是创造垂直速度的过程． 相似文献

This paper explores gender dynamics in sport governance with reference to boards of National Sport Organisations (NSOs) in Australia. It is based on a recent study, underpinned by governance and gender theory. Central is the notion of a gender regime, which is characterised by four interwoven dimensions: production, power, emotional and symbolic relations. When applied to governance dynamics in sport boards, this concept permits identification of how gender works. The study involved an audit of 56 NSOs and in-depth interviews with board directors and chief executive officers (n = 26; 9 women and 17 men) from five NSOs. This paper reports on the results of three NSOs. The data suggest that directors’ participation in sport governance was not uniform in terms of gender dynamics. Three gender regimes were identified: masculine hegemony, masculine hegemony in transition and gender mainstreaming in process. Only the latter provided significant opportunities for gender equality in governance while the former two imposed significant constraints. Central to the regime associated with gender equal governance was a combination of presence of women on the board, the occupation of influential board roles by women, active support of women directors by influential men on the board and a commitment to equality in governance as equal participation by both men and women. 相似文献

Gymnastics vaulting relies on a specialized take‐off board for propulsion during the take‐off phase of the vault. There is little information on the vault board and its behaviour. The aim of this study was to characterize the behaviour of the vault board during handspring drill take‐offs of young male gymnasts (n = 36). The side of the top surface of the vault board and the wooden base were marked with three reflective markers, placed at the end of the vault board nearest the vault table and the centres of the two rearmost coil springs. The vault board surface was divided into two areas, rear and middle, based on marker location. The gymnasts’ groups were determined from the location of the gymnast's lateral malleolus at vault board contact. Landings with the malleolus directly above or behind the rearmost marker were considered rear landings; landings with the malleolus forward of the rearmost marker were considered middle landings. Marker movements were automatically digitized and the right malleolus was hand digitized at 120 Hz. The maximum vertical displacement, vertical deflection time, and vertical velocity at take‐off of the vault board markers did not differ statistically between board contact groups (all p > 0.05). The lateral malleolus velocity components also did not differ between board contact groups. Some low to moderately strong correlations were observed between the various marker displacements, durations and take‐off velocities. Modest correlations were obtained between board markers and right malleolus velocities. The results indicate that foot contact on the vault board, as defined here, did not result in differences in board marker behaviour or right lateral malleolus velocities. This information does not support the idea that vault board contacts at the rear of the vault board are worse than contacts near the middle of the vault board. More research is needed to ascertain the role of the vault board's vibration characteristics to whole body actions that are observed in the subsequent preflight phase. 相似文献

Research on the roles of the board of unitary board systems is well established, while explorations of dual board systems are very limited. We know little about nonprofit sport organisations board roles in countries such as Taiwan that operate with a dual board structure. In consequence, this study explored the roles taken by the board of directors and the board of supervisors in Taiwanese nonprofit sport organisations. Four overarching board of director roles were identified: manage vision and purpose; board duty; human resource and fundraising; and stakeholder focus. For the board of supervisors two primary functions emerged: monitoring results; and board duty and process. The findings of the study extend our understanding of the governance of nonprofit sport organisations and the differences that exist between dual board and single board systems of governance. 相似文献
