目前,用以评定心脏血管机能的运动负荷试验有一些不足之处,例如,较为广泛使用的台阶试验,台阶只分男女两种高度,登台持续时间也较长(5分钟),不易被人接受,尤其不适用于儿童少年。此外,评定时既未考虑个体身高体重的差别,也未考虑相对安静心率的差别。这种评定方法不够理想。 At present, there are some shortcomings in the exercise load test for assessing cardiovascular function. For example, the more widely used bench test, which has only two steps for men and women and a long duration (5 minutes), is not easily accepted , Especially not suitable for children and adolescents. In addition, the assessment did not take into account the difference between height and weight of individuals, but also did not consider the relative difference between the heart rate. This assessment method is not ideal.
