【摘要】 目的:通过备战大赛期女子拳击运动员力量素质训练方法的个案研究,旨在实现综合竞技水平和运动成绩的提高。方法:以女子拳击60kg级别运动员董×为研究对象,设计并实施个体化力量素质训练计划,主要通过实验法对训练准备期、备战期实验前后等速肌力测试、综合力量素质测试、身体成分测试以及血清激素四部分内容相关指标进行统计分析,以调控力量素质训练方案。结果:等速肌力测试反映实验后膝关节峰力矩、平均功率(除右侧伸肌群快速力量测试外)与实验前同名同侧肌群比较各提高10%左右,但屈伸肌群比值实验前后变化不大;实验后躯干左右侧旋转能力有明显提高,右旋优于左旋。综合力量素质测试俯卧撑、1min仰卧起坐实验前后无显著性差异(P>0.05),1min击打沙袋、卧推、平推实心球、左右手握力实验前后比较呈显著性差异(P<0.05)。身体成分测试指标实验前后无显著性差异(P>0.05)。血清激素指标睾酮、睾酮/皮质醇实验前后比较呈显著性差异(P<0.05)。结论:力量素质的针对性训练,董×比赛中竞技对抗能力和击打力量有明显提高,伦敦赛场发挥稳定,取得第五名佳绩。通过实验前后相关指标比较大部分力量素质指标有了较明显提高,但仍存在一定的力量薄弱环节有待改进。更多还原

【Abstract】 Objective:In order to realize comprehensive competitive level and improving in sports performance,we studied the strength training method of women boxing athlete on preparing for the competition period.Methods:We chose women’s boxing 60kg level athletes,Dong x for study,and designed the individual strength training plan to do the statistical analysis in training prepared period and preparation for competition period before and after the experiment.Results:Isokinetic muscle strength testing reflected the average power of knee joint after peak torque,(except the right extensor strength test)with the same name before the experiment comparing the ipsilateral limb increased about 10%,although the flexor and extensor ratio experiment changed little.The trunk lateral rotation ability is improved obviously after the experiment and right-handed preceded left-handed.There was no significant difference in push-ups,sit-ups 1minutes and body composition indexes before and after the experiments(P>0.05).Oneminute hit sandbags,bench press,push a solid ball,around the hand grip test,testosterone and/cortisol had significant differences(P<0.05).Conclusions:The athletic ability and impact strength of Dong X increased after strength training and she played stability and gained the fifth in London.Most of the power quality index had been significantly improved through the test,but there was still a certain weak strength should be improved.更多还原
