The effect of 1 hr of intensive exercise per day on protein breakdown was studied in a group of young male volunteers (20-25 years old) who were on a meat-free diet during the entire period of the study. Urinary 3-methylhistidine and creatinine were estimated as index of protein degradation. When studied over a period of 24 hr at different time points, the mean rates of 3-methylhistidine excretion were 2.4 and 2.9 nmole/min/kg for the day of exercise and nonexercise, respectively. Immediately following the exercise period, 3-methylhistidine and creatinine excretion rates decreased significantly.
在一组年轻男性志愿者（20 - 25岁）中研究了每天1小时的高强度运动对蛋白质分解的影响，这些志愿者在整个研究期间都遵循无肉饮食。测定尿中3 - 甲基组氨酸和肌酐作为蛋白质降解的指标。在24小时内的不同时间点进行研究时，运动日和非运动日3 - 甲基组氨酸的平均排泄率分别为2.4和2.9纳摩尔/分钟/千克。运动期结束后，3 - 甲基组氨酸和肌酐的排泄率立即显著下降。
