影响跳远助跑准确性的因素 总被引：4，自引：0，他引：4
跳远助跑准确性的重要意义,已尽人皆知,本文化影响跳远助跑的准确性因素进行了分析和研究。影响助跑准确性因素分析跳远运动员能否准确地踏上起跳板,这在运动员起跳瞬时后才能知道。故此,我认为助跑起跳的准确性直接影响到技术的发挥和比赛的胜负,因而提高跳远助跳的准确性十分重要。世界高水平男子跳远比赛助跑成功率达75％左右。然而,我国优秀男子跳远运动员在国内和国外的一些重大比赛中,助跑成功率大大低于这个比例。如第45届全国运动会男子跳远决赛助跑成功率都不到68．5％;又如,一个运动员连续失败2、3次,那么他的实力和水… 相似文献

我国优秀跳远运动员助跑速度已接近国际优秀运动员的助跑速度,但在助跑过程中表现出助跑节奏和速度不稳定,踏板的准确性较差,运动员普遍在后4步中有明显减速现象,对速度的利用率较低,成为影响我国跳远运动成绩的主要因素之一。因此,研究跳远运动员踏板准确性的影响因素,分析其形成原因,制定相应对策,在训练中有的放矢,以提高跳远运动员在快速助跑中起跳踏板的准确性,是目前跳远运动训练亟待解决的问题之一。 相似文献

The purpose of the present investigation was to examine the concurrent and construct validity of the three-mile (4.83 km) run as a field test of aerobic capacity. Subjects included 109 college-aged males whose three-mile run time (M = 1310.31 +/- 184.48 s) was measured. Fifty of the subjects were given a maximal treadmill stress test, and their peak oxygen consumption (VO2peak) (M = 54.23 +/- 7.08 ml.kg-1.min-1) was measured. The three-mile run was conducted on an outdoor 0.25 mile (0.425 km) track, and split times were recorded each 110 yds (100.32 m) for the first and last laps and total time was recorded for laps 2 through 11. The correlation coefficient between the run time and VO2peak was -.58, indicating only moderate concurrent validity for the run as a field test for aerobic capacity. A factor analysis conducted on the split time data revealed a three-factor structure of a stable pace phase, an initial sprint, and a final sprint with the stable pace factor accounting for most of the common factor variance (69%). The three-mile run time was used to discriminate successfully between two known groups of subjects in aerobic capacity. These data provide a degree of support for the construct validity of the three-mile run as a field test of aerobic capacity. 相似文献

Abstract The purpose of the present investigation was to examine the concurrent and construct validity of the three-mile (4.83 km) run as afield test of aerobic capacity. Subjects included 109 college-aged males whose three-mile run time (M = 1310.31 ± 184.48 s) was measured. Fifty of the subjects were given a maximal treadmill stress test, and their peak oxygen consumption (VO2peak) (M = 54.23 ± 7.08 ml.kg?1.min?1) was measured. The three-mile run was conducted on an outdoor 0.25 mile (0.425 km) track, and split tunes were recorded each 110 yds (100.32 m) for the first and last laps and total time was recorded for laps 2 through 11. The correlation coefficient between the run time and VO2peak was -.58, indicating only moderate concurrent validity for the run as afield test for aerobic capacity.

大学生健康体适能心肺耐力测试指标效度的比较研究 总被引：3，自引：1，他引：2
以最大耗氧量作为心肺耐力测试项目的效度检验指标,通过实验与比较观察方法,对我国大学生健康体适能的心肺耐力评价指标——台阶试验和耐力跑(男1000m,女800m)两项选测项目的测量效度进行了对比研究。结果显示:大学生台阶试验指数和耐力跑成绩之间无显著线性相关;最大耗氧量与台阶试验指数无明显的相关关系,而与耐力跑成绩呈现相关关系。笔者认为,在确定我国大学生健康体适能评价指标时,选择耐力跑项目作为测试指标能够更为客观、有效地反映心肺耐力的测试目标。 相似文献

The purposes of this study were to validate the 12-min swim as a field test of VO2 peak in female recreational swimmers and to compare its validity with that of the 12-min run. The results are contrasted with those previously reported on a comparable group of male recreational swimmers. Thirty-four young women completed 12-min swim, 12-min run, tethered swimming VO2 peak, and treadmill running VO2 peak tests within 3 weeks. Mean (+/- SD) 12-min swim and run distances were 597 +/- 82 and 2,313 +/- 317 m, and mean tethered swim and treadmill run VO2 peak values were 39.2 +/- 4.9 and 45.4 +/- 6.3 ml.kg BW-1.min-1, respectively. Correlation coefficients and standard errors of estimate for predictions of swimming VO2 peak from the 12-min swim (.42 and 4.5 ml.kg BW-1.min-1) and run (.58 and 4.1 ml.kg BW-1.min-1) and for predictions of treadmill run VO2 peak from the 12-min swim (.34 and 6.0 ml.kg BW-1.min-1) and run (.87 and 3.2 ml.kg BW-1.min-1) indicated that the 12-min run was a more accurate predictor of tethered swim or treadmill run VO2 peak than the 12-min swim. These data are in close agreement with our previous study on young male recreational swimmers. We conclude that the 12-min swim has relatively low validity as a field test of peak aerobic power and that it is not an equally valid alternative to the 12-min run in young adult female recreational swimmers.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

ABSTRACT The purpose was to examine the feasibility of the 20m shuttle run test with music and to test its concurrent validity with the original 20m shuttle run test. A total of 386 adolescents (14.5±1.6 years old, 48.9% boys) participated in our study. A self-reported questionnaire was used to assess student’s perception about the 20m shuttle run test with music and the original and to assess perceived exertion. Participants performed randomly the 20m shuttle run test with music and original two weeks apart. Average and maximum heart rate were monitored with heart rate monitors. The 20m shuttle run with music was a feasible test for measuring cardiorespiratory fitness in adolescents. The concurrent validity showed mean differences of 5.1±14.6 for shuttles, 0.3±0.8 km/h for speed, 0.5±4.1 for stages, and 1.5±4.1 for VO2max (all p<0.001) in favour of the 20m shuttle run with music vs. the original 20m shuttle run test. Mean difference for the rating of perceived exertion was 0.4±2.5 points (p=0.003). No significant difference was found between boys and girls. In conclusion, the 20mSRT-music is feasible and presents a good concurrent validity in adolescents, independently of the sex and it will be an alternative and good approach to assess cardiorespiratory fitness. 相似文献

助跑速度与跳远成绩之间存在高度的相关 ,是影响跳远成绩的主要因素。在当今世界跳远助跑速度越来越快且助跑速度日趋接近的今天 ,踏跳技术的差异已成为决定成绩优劣的一个重要指标。因此 ,跳远成绩不仅取决于助跑速度 ,而且在较大程度上受到踏跳技术和踏跳能力的制约。 相似文献

研究表明 :①随着助跑速度的逐渐加快 ,运动员下肢肌承受的冲击载荷也随之增大。当助跑速度所造成的冲击载荷在运动员下肢肌的承受能力的范围内时 ,运动员能够通过下肢肌的积极主动的退让缓冲来迅速平衡外部载荷 ,产生良好的缓冲和蹬伸效果。②当助跑速度超出了运动员的适宜助跑速度的范围时 ,运动员不能通过积极主动的退让缓冲来迅速平衡外部载荷 ,缓冲和蹬伸效果下降。 相似文献
