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。
In accordance with the detailed requirements of national physical fitness monitoring, 36267 adults aged 2059 were tested by step test. The changes of resting heart rate, recovery heart rate and step index in different age groups were statistically analyzed and found to be related to age. The resting heart rate decreased with age. The increase of heart rate after exercise decreased with age, but recovered more slowly. The comparison of resting heart rate, height, body weight and post-exercise recovery heart rate and step index showed that resting heart rate, height and heart rate were positively correlated with post-exercise recovery, but negatively correlated with step index, of which resting heart rate Correlation is high, while weight is not related to the step index. It is suggested that the step index can be used as an index to evaluate the cardiovascular system function in the general public’s physical fitness test. Further research and exploration can be made on the calculation methods and evaluation criteria.
