摘要
目的:探讨绳梯练习对11～12岁儿童30 m直线冲刺成绩的影响,进一步验证其对儿童的益处和适用性,为制定科学的儿童训练计划提供依据.方法:以大兴体育运动学校11～12岁的短跑队队员为实验对象,进行为期9周(2次/周,15 min/次,于周一、周三上体育课时进行练习)的实验研究.将其分为实验组和对照组,每组男生与女生各8名,两组儿童无显著性差异(P>0.05).其中,实验组除日常训练外,还要进行绳梯练习,对照组仅完成日常训练内容,不进行绳梯练习,测试收集30 m冲刺成绩数据进行分析讨论.结果:实验结果表明,通过9周干预训练后,实验组儿童的30 m直线冲刺成绩相比对照组有显著性差异(P<0.05),且成绩提高幅度优于对照组.结论:实验组儿童30 m冲刺成绩提高幅度优于对照组,绳梯练习对于提升11～12岁儿童30 m直线冲刺成绩有积极作用.
Abstract
Objective: To explore the effect of rope ladder exercises on the 30-meter straight sprint performance of 11～12-year-old children, and further verify their benefits and applicability to children, so as to provide a basis for the development of scientific children training plans. Method: The 11～12-year-old sprinting sprinters in Daxing Sports School were selected as experimental subjects for a 9-week (twice a week, 15 minutes each time, in physical education classes on Mondays and Wednesdays) experimental study. They were divided into the experimental group and the control group with 8 boys and 8 girls in each group, and there was no significant difference between the children in the two groups (P> 0.05). The experimental group performed rope ladder exercises in addition to daily training, the control group only completed daily training without rope ladder exercises, and the experiment collected their 30-m sprint performance data for analysis and discussion. Result: Experimental results showed that after 9-week intervention training, the experimental group had a significant difference in 30-m straight sprint performance compared with that of the control group (P< 0.05), and its performance improvement was better than that of the control group. Conclusion: The improvement of the 30-m straight sprint performance of the children in the experimental group was better than that in the control group, which showed that rope Ladder exercises had a positive effect on improving the 30-m straight sprint results of children aged 11～12.
