Post-resistance exercise hypotension in patients with intermittent claudication.

OBJECTIVE

To verify the acute effects of resistance exercise on post-exercise blood pressure in patients with intermittent claudication.

METHODS

Eight patients randomly underwent two experimental sessions: a session of resistance exercise (R: 6 exercises, 3 sets of 12, 10 and 8 reps with a perceived exertion of 11 to 13 on the 15-grade Borg scale) and a control session (C: resting on exercise machines).

RESULTS

Before and for 60 min following an intervention, auscultatory blood pressure was measured while subjects rested in a sitting position. After the C session, systolic, diastolic and mean blood pressures did not change from the pre-intervention values, while these values decreased significantly after the R session throughout the entire recovery period (greatest decreases = -14 ± 5, -6 ± 5, and -9 ± 4 mmHg, respectively, P < 0.05).

CONCLUSION

After a single bout of resistance exercise patients with intermittent claudication exhibited reduced systolic, diastolic and mean blood pressures, suggesting that acute resistance exercise may decrease cardiovascular load in these patients.
