【摘要】：研究目的：我国《国家学生体质健康标准》中,大学生有氧能力的监测指标采用1000m(男)、台阶试验指数已受到很多学者质疑。因此,本文拟借鉴国外有氧能力的间接测定法,并分析各方法的实效性,筛选出一种或一组最佳反映大学生有氧能力的体质监测指标。研究方法：本文拟将最大摄氧量和通气无氧阈作为校标,首先将1000m跑、12min跑、20m往返跑、台阶试验指数与进行相关分析,其次以最大摄氧量为因变量,以筛选出的最优间接测定法为自变量,进行线性回归分析,以确定各方法的优良性。研究结果：(1)在四项间接测定方法中,仅20m往返跑、12min跑与最大摄氧量的有较高的相关性,仅20m往返跑、12min跑与通气无氧阈有相关性；台阶试验指数与最大摄氧量、通气无氧阈的相关性很低,1000m跑与最大摄氧量、通气无氧阈均无相关性。(2)以12mmin跑、20m往返跑建立的最大摄氧量预测回归模型的拟合优度均较高。通过相关性检验和配对t检验对模型的预测效果进行比较,发现12min跑与20m往返跑的预测效果均较好。研究结论：(1)1000m跑成绩与最大摄氧量相对值和无氧阈相对值之间均相关性非常低。因此认为,1000m跑不能很好地间接反映大学生有氧能力的水平。(2)台阶试验指数与最大摄氧量和无氧阈之间均无明显的相关性。因此认为,台阶试验指数不能较好地间接反映大学生有氧能力的水平。(3)12min跑预测模型的回归方程拟合优度较好,模型进行回代检验结果表明预测值与实测值之间无显著性差异。由此推论,12min跑是一项有效地反映大学生有氧能力水平的体质健康监测指标。(4)20m往返跑预测模型的回归方程拟合优度较好,模型回代检验结果表明预测值与实测值之间无显著性差异。因此认为,20m往返跑也可以有效地间接反映大学生有氧能力水平。
[Abstract]:Objective: in the National Student physical Health Standard of our country, the monitoring index of college students' aerobic ability is 1000m (male, step test index), which has been questioned by many scholars. Therefore, this paper intends to draw lessons from foreign indirect measurement of aerobic capacity, and analyze the effectiveness of each method, and screen out one or a group of best reflects the aerobic capacity of college students physique monitoring index. Methods: the maximum oxygen intake and the ventilation anaerobic threshold were used as the calibration criteria. First, the 1000m running for 12min and the 20m round-trip running, the step test index and the correlation analysis were carried out. Secondly, the maximal oxygen uptake was taken as the dependent variable. The optimal indirect determination method was used as independent variable and linear regression analysis was carried out to determine the superiority of each method. Results: among the four indirect measurement methods, there was a high correlation between 12min running for 20m and maximal oxygen intake, only 12min for 20m round-trip running and the threshold of aeration anoxia, step test index and maximal oxygen uptake. The correlation between ventilation anaerobic threshold and maximal oxygen uptake was very low, and there was no correlation between ventilation anaerobic threshold and maximal oxygen uptake. Through correlation test and paired t test, it is found that the prediction effect of 12min and 20m round trip is better. It is concluded that there is a very low correlation between the results of the 1 / 1 / 1 / 10 / 1 / 1 / 10 / 1 / 10 / 1 / 10 / 1 / 1 / 10 / 1 / 10 / 1 / 1 / 1 / 1 It is concluded that there is no obvious correlation between the bench test index and the maximal oxygen intake and anaerobic threshold. Therefore, the step test index could not indirectly reflect the level of aerobic capacity of college students. The regression equation of predicting model was better. The result of model retrospect test showed that there was no significant difference between the predicted value and the measured value. It is concluded that 12min running is an effective physique health monitoring index reflecting the aerobic ability level of college students. The regression equation of predicting model is good. There was no significant difference between the predicted value and the measured value. Therefore, it is considered that the 20 m round trip can also reflect the aerobic ability level of college students effectively and indirectly.
