国内学者王清、冯树勇等人研究表明,跳远运动员最后10m的分段速度与成绩相关性高度显著,最后5m的助跑速度越快,则表现出来的成绩越好。赵国雄认为,助跑速度是决定跳远成绩最重要的因素,并且,在所有的影响跳远成绩因素中,助跑速度所起的作用大于70%,它对跳远成绩的影响最大,并与跳远的成绩密切相关。因此,跳远运动员在熟练掌握跳远技术的基础上,助跑速度越快,起跳能力越强,其跳远成绩就会越好。助跑与起跳的完美衔接对于找出适当的助跑距离、  相似文献

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

Abstract

Three anthropometric and eight physical performance measures selected by the author were related by correlational methods to the performance of 87 secondary school boys in the running hop, step, and jump. All variables showed a significant relationship with the criterion beyond the .05 level of confidence. The criterion could be employed as a measure of motor ability since three of the highest single-variable correlations with the criterion were measures that are known predictors of motor ability: the running broad jump (r = .859), 50-yd. dash (r = .815), and standing broad jump (r = .778). Three selected combinations of measures yielded multiple correlations with the criterion which were significant beyond the .01 level of confidence. A regression equation developed from the optimal set of variables that was considered to be feasible for administration in school systems consisted of two items from the Youth Fitness Test Manual: the standing broad jump and the 50-yd. dash.  相似文献

The purpose of this study was to determine the extent to which the mean difference in performance between men and women on selected physical performance tests was related to the sex difference in body fatness. Percent total body fat (% fat) estimated from skinfold thickness measures and performances on the modified pull-up, vertical jump, 50-yard dash, and 12-minute-run tests were measured on 55 male and 55 female college students. Males had significantly less fat and performed significantly better than females on each of the performance tests. Mean differences were 8.2% fat, 20.0 modified pull-ups, 20.8 cm on the vertical jump, 1.3 seconds on the 50-yard dash, and 590 m on the 12-minute run. Linear regression equations predicting performance scores from % fat within the groups of men and women indicated that if body fatness in men and women were similar, performance differences would be reduced, on the average, by 7 modified pull-ups, 4 cm on the vertical jump, .5 seconds on the 50–yard dash, and 146 m on the 12-minute run. These expected changes in performance were 36%, 19%, 38%, and 25% of the mean sex difference in performance on the four physical performance tests, respectively. It was concluded that greater body fatness is one characteristic that partly explains why women, on the average, do not perform as well as men on strenuous tasks requiring movement of the body weight. The sex-specific difference in body fatness should be one factor considered in establishing separate occupational and athletic performance expectations for men and women.  相似文献

优秀女子跳远运动员关英楠的技术潜力分析   总被引:3,自引:0,他引:3  
通过文献资料等方法,将关英楠的跳远技术和专项素质与国外选手进行了比较分析,发现其动态的最大力量弱,最后10m的分段速度减速明显,起跳时垂直分速度占腾起初速度的份额大,成绩损失严重。这一系既是她的不足,也是她的潜力。只要今后加强针对性训练,对提高成绩无疑有很大的帮助。  相似文献

To ensure precise foot placement on the take-off board, long jumpers visually regulate their stride pattern during their run-up. A relationship between how much visual guidance they use and the horizontal distance they jump has not, however, been quantified. Run-up precision is often practiced using run-throughs, which exclude the take-off and, therefore, the high physical stress of the complete long jump. The validity with which this common training method simulates the long jump approach remains, however, to be verified. Four state-standard long jumpers and two heptathletes completed two sessions, each comprising six runthroughs and six competition long jumps. A 50 Hz video camera was manually panned from an elevated platform to film each trial, to enable subsequent gait characteristic evaluations. Linear regression analyses identified that a longer visual regulation phase, measured in time, distance or number of strides, was a key predictor of long jump distance. The number of strides that were visually regulated during the long jump approach was, accordingly, positively correlated with long jump distance (r = 0.67, p = 0.001). The amount of visual regulation used during run-throughs was, however, less than half (p = 0.001) of that observed during long jump approaches. Our results should compel long jump coaches to supplement run-through training with additional visual guidance exercises, to encourage their athletes to visually regulate more of their long jump approach.  相似文献
