股后肌群力量的增强对初中生立定跳远的影响

Effect of Posterior Femoral Muscle Group Strength on Establishment of Long Jump in Junior Middle School Students

目的为了研究增强股后肌群力量训练对初中生立定跳远的影响。方法采用实验法对72名初中生进行测验,采取两种训练方法,即用下肢力量训练与下肢力量训练+专门的股后肌群训练。结果两种训练方法均可提高跳远成绩,对照组、实验组干预前后成绩相比有显著性差异;实验组在增加专门的股后肌群训练的干预后,立定跳远成绩明显优于对照组,干预后的对照组成绩(188.75±24.09cm)与实验组成绩(205.33±26.38cm)存在显著性差异(p=0.007,t=-2.785);从不同性别分析,男、女生在干预后的跳远成绩都有明显提高,男生干预后的对照组(204.00±19.97cm)与实验组(224.50±17.31cm)之间有显著性差异(p=0.001,t=-3.468),女生干预后的对照组(169.69±12.31cm)与实验组(181.38±11.90cm)之间存在统计学上差异(p=0.010,t=-2.730),男生在第4周之后实验组与对照组有明显性差异,女生则在第12周之后实验组与对照组之间出现显著性差异。结论下肢力量训练可以提高跳远成绩,但增加专门的股后肌群力量训练对提高立定跳远的成绩效果更佳。

Objective To study the effect of increasing the strength training of posterior femoral muscle group on the establishment of standing long jump in junior middle school students.Methods 72 junior high school students were performed by lower limb strength training and lower limb strength training plus special training of posterior femoral muscle group respectively.Results Both training methods could improve their long jump performance,and there was a significant difference between the results of the control group and the experimental group before and after intervention.The standing long jump performance of the experimental group was significantly better than that of the control group after the intervention of adding special training of the posterior femoral muscle group.The results of the control group after the intervention were(188.75±24.09 cm)and that of the experimental group were(205.33±26.38 cm).There was a significant difference between the results of the experimental group and the control group.The difference was(p=0.007,t=-2.785).From different gender analysis,the long jump performance of boys and girls after intervention was significantly improved.There was a significant difference between the control group(204.00±19.97 cm)and the experimental group(224.50±17.31 cm)(p=0.001,t=-3.468).There was a statistical difference between the control group(169.69+12.31 cm)and the experimental group(181.38±11.90 cm)(p=0.010,t=-2.730).There were significant differences between the experimental group and the control group after the fourth week for boys,and between the experimental group and the control group after the twelfth week for girls.Conclusion Lower limb strength training can improve long jump performance,but adding special strength training of posterior femoral muscle group is better for improving standing long jump performance.
