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

Summary Purpose To clarify whether pulmonary oxygen uptake kinetics ( τ V ˙ O 2 p) at the onset of moderate‐intensity exercise can predict acute physiological responses to resistance exercise training ( RET ). Methods We investigated the relationship between τ V ˙ O 2 pand 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, peakV ˙ O 2and τ V ˙ O 2 pwhile 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 . Results There were significant positive associations between τ V ˙ O 2 pand the rates of increase in Bla, HR , SBP and RPP during a single RET session ( P <0·05). However, the anaerobic threshold and peakV ˙ O 2did not significantly affect these parameters. Conclusion The τ V ˙ O 2 pis a useful evaluation index for predicting acute physiological responses to RET .
