A single multi-joint high-intensity resistance exercise involving large muscle groups elicits post-exercise hypotension in normotensive-trained women: a crossover trial
The aim of this study was to investigate whether only 1 multi-joint resistance exercise involving large muscle groups can elicit post-exercise hypotension (PEH).
A randomized crossover trial was conducted with 13 normotensive-trained women (21.8 ± 2.1 years; 23.5 ± 3.1 kg/m2; blood pressure 100.4 ± 4.9/58.6 ± 5.6 mmHg). They were submitted randomly into two sessions: (a) a single multi-joint resistance exercise session (3 sets of 20 repetitions at 80% of 20 repetitions maximum performed on double-leg press machine) and (b) control session (15 min of resting in a seated position). Blood pressure (BP) was measured before and at 20, 40, and 60 min following the control and resistance exercise sessions.
It was observed a reduction in systolic BP at 40 min (4.8 ± 4.6 mmHg) and 60 min (6.3 ± 4.3 mmHg) post-exercise with a moderate magnitude (d ≥ 0.79, p < 0.05). Moreover, 10 participants (i.e., 77% of the sample) decreased at least 3 mmHg of systolic BP post-exercise. There was no change in diastolic BP and mean BP post-exercise (p > 0.05).
A single multi-joint high-intensity resistance exercise involving large muscle groups and performed within a very low time commitment elicited systolic PEH in normotensive-trained women.
