一、内容摘要本研究采用光电分段计时的研究方法,测量体育系新生100M跑的各段时间。样本90。通过对所收集数据分析、研究,结果表明加速能力、最大速度、速度耐力三者均与百米成绩密切相关。我们把结果中最大速度、速度耐力、后程下降曲线与同一年龄较优秀运动员作比较后,本文认为,体育系新生优先发展速度耐力对提高百米成绩更有利。另在样本中选出后程下降率临界值为93.7%的33个样本、推导出百米成绩Y与最大速度段时间X_2的回归方程:Y=1.573+9.915X_2±0.372。通过此方程,可对与我们测试水平相当的运动员的最大速度与最
First, the summary of this study using optical time-staging method to measure the Department of Physical Education freshman 100M run each period of time. Sample 90. Through the analysis and research on the collected data, the results show that acceleration, maximum speed and speed endurance are all closely related to the performance of 100 meters. After comparing the maximal speed, speed endurance and descent curve of the results with the elite athletes of the same age, this paper argues that it is more advantageous to improve the speed and stamina of freshmen in PE department to improve the performance of 100 meters. In addition, 33 samples with the descent rate of descent rate of 93.7% were selected from the sample, and the regression equation of the hundred meters Y and the maximum speed time X_2 was derived: Y = 1.573 + 9.915X_2 ± 0.372. Through this equation, the maximum speed and the maximum of an athlete comparable to our test level can be obtained
