[Free amino acids in blood plasma during hypokinesia]

The study (in a Hitachi KLA-3B analyzer) of 17 free amino acids in plasma of six healthy men under ambulatory and hypokinetic conditions demonstrated the following trend: by day 15 of clinostatic hypokinesia the content of most amino acids increased and by day 30 decreased, reaching the pretest level of falling below it. These variations in the amino acid concentration are viewed as a consequence of the modified relations between anabolic and catabolic processes induced by adaptation to hypokinesia. It is emphasized that the nutrition pattern was different in the hypokinetic study.
