Abstract des Autors
The purpose of this study was to examine the oxygen pulse (O2p) time course i.e. oxygen consumption (VO2)/heart rate (HR), in severe exercise. This was to check whether HR can be a predictor of VO2 in severe exercises known as inducing a VO2 slow component. Eight mid level runners performed on track two maximal tests. The first incremental test was devoted to determine VO2max, lactate threshold (LT) and the associated velocity (vVO2max). The second one was a continuous severe run at 95% of vVO2max. Main results show that, as expected, HR and VO2 elicit a slow component. Despite this HR slow component, the maximal HR value remained significantly lower than the maximal HR obtained in the incremental test. In opposite, VO2 reached VO2max. However, the steady state of the O2p from 10 to 90% of the time limit allows to estimate VO2 from HR monitoring. Verf.-Referat
