核心力量在高水平标枪运动员训练中的实验研究

运用实验、文献资料、数理统计、比较和逻辑分析等方法,对实验组的高水平标枪运动员进行12周的身体核心力量练习,验证核心力量练习对标枪成绩提高的促进作用.结果显示:实验组实验前后5项专项力量素质指标均发生显著性差异(P<0.05),而对照组只有前后抛实心球发生显著性差异.实验组的专项速度以及身体核心稳定性指标均发生显著性差异(P<0.05),其中单足闭眼站立时间呈现出明显差异(P<0.01).试验前后实验组受试者身体核心力量以及标枪成绩均出现显著性差异,且实验组与对照组实验前后组间标枪成绩差异显著性非常明显(P<0.01).说明核心力量训练能有效提高受试者神经系统对肌肉的募集速度、支配的准确度,增强受试者投掷标枪过程中身体核心部位的稳定性、平衡性以及力量链动态传递的有效性.

Experimental Research on Core Strength Exercises of Javelin Training

By using the experimental methods, literature review, statistical comparison and logical analyses, the core strength exercises of improving the performance of javelin thrower in 12 weeks were investigated. The results showed that there were significant difference （P〈 0.05） of five indexes in experimental group of 5 special strength indexes after the experiment. However, there was only significant difference （P 〈 0. 05） in before and after throwing solid ball of control group. The special speed indexes and the body core strength showed significant difference（P 〈 0.05）, the time for single foot standing with eyes closed of the experimental group showed very significant difference （P 〈 0.01）. The body core strength and javelin result of experimental and control groups showed significant difference （P 〈 0.05）, and group javelin result showed very significant difference of the experimental group and the control group before and after the experiment （P 〈 0.01）. The findings Indicated that the core strength training could effectively improve the accuracy of the subjects of nervous system on muscle, raise speed control, enhance the stability of core parts of the body, balance and effectiveness of continuous dynamic delivery when the subjects in javelin - throwing process.
