迎面接力跑是一项对抗激烈的集体性项目,它不仅可以发展学生的奔跑能力,还可以培养学生的团队协作意识和勇于拼搏精神,深受广大师生的欢迎。本文介绍了一种新的交接棒方法,以及教学实践经验,旨在为迎面接力跑教学提供参考。一、交接棒新法传统的迎面接力跑交接棒采用立棒式,奇数棒的学生握接力棒的下端,偶数棒的学生握接力棒的上端。握接力棒上端跑不自然,有时还会被接力棒碰到。本文重在介绍一种新的横棒式交接棒方法,以右手交接棒为例。 相似文献

In short track speed skating, the relay exchange provides an additional strategic component to races by allowing a team to change the skater involved in the pack race. Typically executed every 1½ laps, it is the belief of skaters and coaches that during this period of the race, time can be gained or lost due to the execution of the relay exchange. As such, the aim of this study was to examine the influence of the relay exchange on a team’s progression through a 5000?m relay race. Using data collected from three World Cup relay events during the 2012–2013 season, the time taken to complete the straight for the scenarios with and without the relay exchange were compared at different skating speeds for the corner exit prior to the straight. Overall, the influence of the relay exchange was found to be dependent on this corner exit speed. At slower corner exit speeds (12.01–13.5?m/s), relay exchange straight times were significantly faster than the free skating scenario (P?<?0.01). While at faster corner exit speeds (14.01–15?m/s), straight times were significantly slower (P?<?0.001). The findings of this study suggest that the current norm of executing relay exchanges every 1½ laps may not be optimal. Instead, varying the frequency of relay exchange execution throughout the race could allow: (1) time to be gained relative to other teams; and (2) facilitate other race strategies by providing an improved opportunity to overtake. 相似文献

接力比赛是一项团体项目,由于竞争激烈.可观赏性很强。在各级田径运动会的比赛中起着举足轻重的作用。一个接力队成绩的好坏也反映出一个学校(团体)的教学与训练的水平。成绩的优劣除了取决于几名运动员的个人短跑成绩外,每个运动员之间的传接棒水平,传接棒成功率的高低,也直接影响着接力队的成绩。 相似文献

对优秀男子篮球运动员运动寿命的研究 总被引:4,自引:0,他引:4
优秀男子篮球运动员的运动寿命在此特指运动员竞技能力达到高水平以后 ,正常情况下持续到不能再适应其原来参加的高水平重大比赛而退役的一段时间。这段时间的长短受到多方面因素的制约和影响 ,是一个复杂的问题。本文通过对不同时期中外优秀男子篮球运动员年龄的统计发现 :他们的年龄普遍有增长的趋势 ;他们的运动寿命普遍有延长的趋势。我们应该重新认识和划分优秀男子篮球运动员的年龄阶段 ,在注重培养新秀的同时 ,也要充分发挥“老将”的作用。 相似文献

This study sought to determine the association of relative age and performance of young elite basketball players. The distribution of the birth dates, heights, positions, classification and performance of the male and female participants (n = 2395) of the U16, U18 and U20 European Basketball Championships were analysed. We found an over-representation of players born during the initial months of the year in all groups, with the relative age effect being more evident in players of the U16 and U18 groups, than of the U20 teams, particularly in male squads. Nevertheless, in the U20 championships, those teams that had the oldest players performed the best. In all championships, the oldest participants played more minutes. In addition, relatively older male players scored better in total points and in performance index rating when results were normalised to played time. This effect was not found for female players. Regarding playing position, different distributions of birth dates were observed due to each position’s physical requirements. Thus, basketball coaches and managers should keep these results in mind when they select players because if not, they might subject players who are born towards the end of the year to a negative selection bias. 相似文献
