To investigate the important index of maximum oxygen uptake in evaluating cardiopulmonary function and to provide a basis for the evaluation of cardiopulmonary function for adolescents, a total of 200 healthy adolescents aged 12-14 were selected, and these 200 subjects were randomly assigned to the modeling group and the test group. In the first stage, data of 150 subjects were randomly selected, and the regression equation for VO2max was established by adding independent variables such as gender, age, height, weight, body mass index, and resting heart rate. In the second stage, the remaining 50 subjects were selected as the test group to test and evaluate the prediction effect of the prediction model. The results showed that the correlation coefficient between the measured value of maximal oxygen uptake and the predicted value was 0.983, and the significance level was 0.000, which was significantly lower than 0.01 correlation, indicating that there was an obvious concomitant relationship between the two values. The maximum oxygen uptake calculated by this equation is good and has a good application prospect.
为了研究最大摄氧量这一重要指标在评价心肺功能中的作用,为青少年心肺功能评价提供依据,选取了 200 名 12-14 岁健康青少年,将 200 名研究对象随机分为建模组和验证组。首先,随机抽取 150 名受试者,加入性别、年龄、身高、体重、体质量指数、静息心率等自变量,建立 VO2max 的回归方程;然后,选取剩余的 50 名受试者作为验证组进行测试,评价预测模型的预测效果。结果显示,最大摄氧量实测值与预测值的相关系数为 0.983,差异有统计学意义(P<0.001),明显低于 0.01 相关,说明两者之间存在明显的伴随关系。该方程计算出的最大摄氧量良好,具有较好的应用前景。
