| 尿羟脯氨酸排泄规律及力量练习对其影响 |

| 摘 要： | 观察了男性成人安静时及一次性力量练习后24h尿羟脯氨酸（HPP）排泄规律。结果：安静状态及力量练习后24h的各段尿羟脯氨酸的排泄速率（mg／min）、羟脯氨酸／肌酐（Hyp／Cr）比值间均无明显差别（P＜0．05）；运动前后各段的对应值之间也无明显差异（P＜0．05）；运动前后各段尿羟脯氨酸总量，Hyp／Cr比值与24h总尿Hyp相关性较高的时间段是否20：00～23：00相关系数均在0．80以上（P＜0.05）。这些结果表明：安静时人体尿Hyp排泄量4h内比较均匀；一次性高负荷力量练习不能改变运动后24h尿Hyp总量和不同时期段的尿Hyp排泄速率。

| Abstract: | Twenty-four hr urea HYP excretion at rest and after a single bout of weight training was examined among male subjects. The results indicated: there were no significant differences in urea HYP excretion velocity (mg/min) and urea HYP/CR among various phases either at rest or after weight training; the values of urea excretion velocity and HYP/CR of the same phase at rest and after exercise were not significantly different; there existed a high correlation between urea HYP/min and HYP/CR of the phase of 20: 00-23:00 and the total 24hr urea HYP;the correlation coefficients were all above 0. 80 (p< 0. 05). These results suggested that human urea HYP excreted homogenously at rest, and total urea HYP post-exercise and urea HYP excretion velocity at various phases did not alter by a single bout of heavy-load weight training. |
