【摘要】 按照国家国民体质监测的细则要求,对36267名2059岁的成年人进行台阶测试,统计分析了不同年龄段人群安静心率、恢复期心率和台阶指数的变化规律,发现其与年龄存在一定的相关。安静心率随年龄增长呈下降趋势,运动后心率的升高随年龄的增长而减少,但恢复也较慢。对受试者安静心率、身高、体重与运动后恢复期心率、台阶指数的相关性比较显示,安静心率、身高与运动后恢复期心率呈正相关,而与台阶指数呈负相关,其中安静心率的相关性较高,而体重则与台阶指数不相关。提示台阶指数作为大众体质测试评价心血管系统功能的指标,在计算方法、评价标准等方面还可进一步研究探索。更多还原

【Abstract】 Based on requirements of national fitness examination, this study conducted the step tests in a sample of 36267 adults aged from 20 to 59 years old. Based on the results of tests, this study analyzed the changed principles of heart rate, recovered heart rate and step test indexes of the adults. The results showed that all the indexes have obvious correlation with the factor of age. The heart rate in the quiet state decreased when the age goes up, the heart rate of the young people in the exercises increased more than that of the aged, but recovered slower among the old people. The results of the correlation analysis between quiet heart rate, body height, body weight and recovered heart rate, step test index showed that there was positive correlation of heart rate, body height and recovered heart rate, and there was negative correlation between heart rate, body height and the index, the correlation coefficient between heart rate and the index was highest. There was no correlation between body weight and the index. It is suggested that step test indexes should be applied to evaluate the function of cardiovascular system, which should be studied about its calculating way and standard.更多还原
