中文摘要:
      以国内男子优秀蹦床运动员高磊为研究对象,记录高磊在完成难度17.5成套动作和18.2成套动作过程中各单次难度动作的高度分和位移分,并观察各单次难度动作高度分和位移分的时间演变规律及其与客观分总分的相关关系。发现难度18.2成套动作的客观分总分要略高于难度17.5成套动作,且难度17.5成套动作的稳定性也显著优于难度18.2成套动作。位移分和难度分之间总体呈正相关关系,提示动作的高度分和位移分是紧密联系、相互促进的。随着动作次序的增加,高度分呈单调递减趋势。难度17.5成套动作的高度分呈现下降-略上升-下降的特征,而难度18.2成套动作前6个动作的高度分呈直线下降趋势,第6个动作后高度分呈平缓下降趋势。在难度17.5成套动作中,第3、第5、第7个动作是最主要的扣分环节。在难度18.2成套动作中,第2、第5、第7个动作是最主要的扣分环节,此外,第3、第6、第8、第10个动作也是扣分环节。基于上述结论,制定针对性训练方案,通针对性训练前后日常测验成绩的统计分析,验证本研究对高磊技术动作诊断分析结果的有效性和价值。
英文摘要:
      Taking Gao Lei, an elite male trampoline athlete in China, as the research object, this study recorded the scores of horizontal displacement and time of flight of each single difficulty movement in the routines in difficulty value of 17.5 and 18.2. The time evolution characteristics of horizontal displacement score and time of flight score of each single difficulty movement and the correlation between it and objective score were also observed and analyzed. It found that the objective score in total of the routine in difficulty value of 18.2 was slightly higher than that in difficulty value of 17.5. And the stability in difficulty value of 17.5 was significantly better than that in difficulty value of 18.2. There was a positive correlation between the horizontal displacement score and the difficulty score, which showed that the scores of horizontal displacement and time of flight were closely related and mutually promoted. With the increase of the movement sequence, the time of flight score showed a monotonically decreasing trend. The time of flight score of a set routine in difficulty value of 17.5 showed the characteristic of decline, slight rising and then decline. while the time of flight score of the first six movements of routine in difficulty value of 18.2 showed a straight downward trend, and then it showed a steady decline after the sixth movement. In the routine in difficulty value of 17.5, the third, fifth and seventh movements were the main deduction items. The second, fifth and seventh movements were the main deduction items in the routine in difficulty value of 18.2. In addition, the third, sixth, eighth and tenth movements were also the main deduction items. Based on the above conclusions, a targeted training was developed, and the statistical analysis of the daily test scores before and after the targeted training was conducted to verify the scientific validity and value of this study on the diagnostic analysis results of Gao Lei's technical movements.
