Creatinine is a biochemical marker for assessing how untrained people adapt to fitness training loads

Abstract

The analysis of the results obtained during a series of experimental studies indicates the need and feasibility of using the indicator of basal level of creatinine concentration in blood during fitness training, especially in the conditions of high intensity and low volume training load regime (<i>R</i> _<i>a</i> = 0.72), as an informative marker for assessing the process of long-term adaptation.
