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.

Carbohydrate and lipid metabolism in rats after hypokinesia.

Hypokinesia (diminished muscular activity) elicits several substantial alterations in carbohydrate and lipid metabolism of animals and man. The aim of this study was to examine certain parameters of carbohydrate and lipid metabolism in blood and tissues of 118 rats weighing 180-220 g, during a 90 days' exposure to hypokinesia (HK) and a 90-days' readaptation period (RP), that is, after the termination of HK. All of the rats were divided into experimental and control groups.

Mineralization of human bone tissue under hypokinesia and physical exercise with calcium supplements.

It has been suggested that physical exercise and calcium supplements may be used to prevent demineralization of bone tissue under hypokinesia (diminished muscular activity). Thus, the aim of this study was to determine mineral content of bones of 12 physically healthy men aged 19-24 years under 90 days of hypokinesia and intensive physical exercise (PE) with calcium lactate (C) supplements. They were divided into experimental and control groups with 6 men in each.
