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。
Urinary hydroxyproline (HPP) excretion was observed 24 hours after resting and one-time strength exercises in male adults. Results: There was no significant difference in urinary hydroxyproline excretion rate (mg / min) and hydroxyproline / creatinine (Hyp / Cr) between 24h and 24h after exercise (P <0.05) ; There was no significant difference between the corresponding values before and after exercise (P <0.05); the period of high correlation between the total urinary hydroxyproline and the Hyp / Cr ratio before and after exercise and Hyp Whether the correlation coefficient between 20:00 ~ 23:00 is above 0.80 (P <0.05). These results show that: Hyp excretion of human urine is relatively uniform within 4 hours after resting; exercise of one-time high-load can not change the total amount of urinary Hyp and urinary Hyp excretion rate at different periods after exercise.
