运动生理中常用的机能试验有15秒原地疾跑、30秒20次起蹲、3分钟原地跑,以及联合机能试验等。但这些试验的运动强度难以定量检测和控制,所以,测试结果也难以精确。为了使试验在负荷相对稳定的情况下进行,近年来国外广泛采用PWC试验来评定人体机能状态。PWC_(170)的运动试验,适用于大学生和运动员。PWC_(170)是指心率达到每分钟170次/时的输出功率。对于老年人和无训练的儿童少年进行运动测验时,可适当降低心率标准,如PWC_(160)或PWC_(150)
Exercise physiology commonly used in functional tests sprint 15 seconds in situ, 30 seconds squat from 30 seconds, 3 minutes running in situ, and joint performance tests. However, the exercise intensity of these tests is difficult to quantitatively detect and control, so the test results are not accurate. In order to test the load is relatively stable under the circumstances, in recent years widely used abroad PWC test to assess human performance status. PWC_ (170) exercise test, suitable for college students and athletes. PWC_ (170) refers to the heart rate reaches 170 times / minute output power. Heart rate standards such as PWC 160 or PWC 150 may be appropriate for exercise testing in older and untrained children and adolescents,
