我国青少年男子蹦床选手身体素质敏感指标筛选及标准研究

Screening and Standard Research on Physical Fitness Sensitive Indicators of Chinese Adolescent Male Trampoline Players

对2017年全国蹦床训练营26名运动员的素质测试成绩进行分析;采用多元逐步回归分析法对10项测试指标进行敏感指标筛选,并建立预测模型。分析结果表明:团身后空翻10次、立定跳远、八级腹桥、20秒肋木举腿对成绩有显著影响,其中团身后空翻10次对成绩敏感度最大,立定跳远、八级腹桥、20秒肋木举腿次之;团身后空翻10次、立定跳远、八级腹桥、20秒肋木举腿与成绩间的多元回归模型公式为Y=597.00-5.25X1-94.38X2-7.04X3-8.00X4。由此构建身体素质单项指标的评价标准,为青少年男子蹦床运动员的身体素质训练及科学选材提供参考。

The physical fitness of 26 adolescent male athletes in the trampoline training camp was tested. Multiple stepwise regression analysis was used to screen the scores of 10 test indicators and establish a predictive model. The results show 10 times back flips,standing long jumps,eight-level abdominal bridges and 20 seconds wall bar leg raise had significant impact on scores. The results showd that the 10 times back flips had the biggest sensitivity to the scores. The multiple regression model formula is Y=597.00- 5.25X 1 -94.38X 2-7.04X 3-8.00X 4. Therefore,the evaluation criteria of the single indicator of physical fitness is constructed to provide references for the training and scientific selection for adolescent male trampoline athletes.
