现代跳远运动员的速度训练     

孟庆袖 《山西师大体育学院学报》2002,17(2):67-68

跳远的起跳技术由打击型、制动型已经发展成速度型(跑步型)。为了适应这种技术,应该重新认识现代跳远运动员的速度训练,它包括发展运动员跑的速度(跑的能力、绝对速度、助跑速度),速度性力量和快速跳跃能力。  相似文献

陈峰 《图书馆杂志》2006,25(2):34-35,40

托管型社区图书馆是新型的社区图书馆办馆模式，具有“委托管理、分馆运作”的体制特点。其建设的现实意义在于建立良好的管理机制，解决社区自行办馆中难以解决的问题；改变“小而全”的办馆模式，为建立地区性公共文献资源共建共享体系奠定基础。  相似文献   

Understanding key performance indicators for breast support: An analysis of breast support effects on biomechanical,physiological and subjective measures during running     

Debbie Risius  Alexandra Milligan  Jason Berns  Nicola Brown 《Journal of sports sciences》2017,35(9):842-851

To assess the effectiveness of breast support previous studies monitored breast kinematics and kinetics, subjective feedback, muscle activity (EMG), ground reaction forces (GRFs) and physiological measures in isolation. Comparing these variables within one study will establish the key performance variables that distinguish between breast supports during activities such as running. This study investigates the effects of changes in breast support on biomechanical, physiological and subjective measures during running. Ten females (34D) ran for 10 min in high and low breast supports, and for 2 min bare breasted (2.8 m·s^?1). Breast and body kinematics, EMG, expired air and heart rate were recorded. GRFs were recorded during 10 m overground runs (2.8 m·s^?1) and subjective feedback obtained after each condition. Of the 62 variables measured, 22 kinematic and subjective variables were influenced by changes in breast support. Willingness to exercise, time lag and superio-inferior breast velocity were most affected. GRFs, EMG and physiological variables were unaffected by breast support changes during running. Breast displacement reduction, although previously advocated, was not the most sensitive variable to breast support changes during running. Instead breast support products should be assessed using a battery of performance indicators, including the key kinematic and subjective variables identified here.  相似文献   

Are gait characteristics and ground reaction forces related to energy cost of running in elite Kenyan runners?

The aim of this study was to determine whether gait cycle characteristics are associated with running economy in elite Kenyan runners. Fifteen elite Kenyan male runners completed two constant-speed running sets on a treadmill (12 km ·h^?1 and 20 km ·h^?1). VO₂ and respiratory exchange ratio values were measured to calculate steady-state oxygen and energy cost of running. Gait cycle characteristics and ground contact forces were measured at each speed. Oxygen cost of running at different velocities was 192.2 ± 14.7 ml· kg^?1· km^?1 at 12 km· h^?1 and 184.8 ± 9.9 ml· kg^?1· km^?1 at 20 km· h^?1, which corresponded to a caloric cost of running of 0.94 ± 0.07 kcal ·kg^?1·km^?1 and 0.93 ± 0.07 kcal· kg^?1· km^?1. We found no significant correlations between oxygen and energy cost of running and biomechanical variables and ground reaction forces at either 12 or 20 km· h^?1. However, ground contact times were ~10.0% shorter (very large effect) than in previously published literature in elite runners at similar speeds, alongside an 8.9% lower oxygen cost (very large effect). These results provide evidence to hypothesise that the short ground contact times may contribute to the exceptional running economy of Kenyan runners.  相似文献   

Cultures of running: characteristics and determinants     

Geoffrey Lassalle  Robin Recours  Jean Griffet 《Sport in Society》2019,22(3):342-360

Based on the studies of Mauss (1935 Mauss, M. 1935. “Les techniques du corps.” Journal de Psychologie 32: 271–293. [Google Scholar]) and Bourdieu (1980 Bourdieu, P. 1980. Le Sens pratique. Paris: Editions de Minuit. [Google Scholar]) on the determination of body techniques by culture and social background, this study seeks to describe the rules, dispositions and habits specific to different forms of athletic running. It is based on a sample of 732 athletes, all of them are the members of French athletics clubs, comprising 220 sprinters, 213 half-distance runners and 299 long-distance runners. Sports practices are different depending on sub-culture affiliation, sociological characteristics and forms of commitment. This being said, simple links between variables should not be transformed into causal connections. Before drawing such conclusions, it is important to identify the nature of the sport studied. This shows that middle-distance and long-distance enthusiasts, traditionally classified in the same family, have less, in common, than those practising sprint and middle distance. These results potentially question the methodological groups and sociological interpretations made by researchers and sports science.  相似文献
