A METHOD FOR ESTIMATING THE ANAEROBIC METABOLISM THRESHOLD BASED ON ANALYSIS OF DYNAMIC CHANGES IN HEART RATE DURING AN EXERCISE TEST

A method is proposed for assessing the anaerobic metabolic threshold (AMT) during incremental physical exertion to the point of failure by analysis of the dynamics of changes in heart rate (HR). The method is based on evaluating AMT in terms of the integral indicator Q, i.e., the area under the curve of the relationship between changes in the relative increase in heart rate and the relative duration of the exertion interval. The method does not require information on the “inflection” points of the heart rate curve either during exertion or in the recovery phase, which overcomes the problem of subjective assessment of the locations of these points.
