Creatine excretion in urine of man under hypokinesia and physical exercise.

It is known that hypokinesia (diminished muscular activity) induces changes in various biochemical parameters of the organism, including creatine. Thus the aim of this study was to determine daily excretion of creatine under 100-days' exposure to hypokinesia (HK) in essentially healthy men, aged 18-23 years. They were divided into two groups with 3 men in each.
