Pulmonary oxygen uptake on-kinetics can predict acute physiological responses to resistance exercise training in healthy young men.

Abstract

To clarify whether pulmonary oxygen uptake kinetics ( ) at the onset of moderate-intensity exercise can predict acute physiological responses to resistance exercise training (RET). We investigated the relationship between and acute metabolic and hemodynamic responses to a single RET session in 27 healthy young adult men. Cardiopulmonary exercise was on a cycle ergometer, and a single RET at 30% or 60% of one-repetition maximum was on a bilateral leg-extension machine. We measured the anaerobic threshold, peak and while cardiopulmonary exercising, and the rates of increase in blood lactate (Bla), heart rate (HR), systolic blood pressure (SBP) and rate pressure product (RPP) for a single RET. There were significant positive associations between and the rates of increase in Bla, HR, SBP and RPP during a single RET session (P<0·05). However, the anaerobic threshold and peak did not significantly affect these parameters. The is a useful evaluation index for predicting acute physiological responses to RET.
