CUCATO, Gabriel Grizzo et al. Post-resistance exercise hypotension in patients with intermittent claudication. Clinics [online]. 2011, vol.66, n.2, pp.221-226. ISSN 1807-5932. http://dx.doi.org/10.1590/S1807-59322011000200007.
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.
