摘要

Objective To analyze the posteffects of a single bout of resistance exercise on cardiovascular parameters in patients with peripheral artery disease (PAD). Design Randomized cross-over. Materials and methods Seventeen PAD patients performed two experimental sessions: control (C) and resistance exercise (R). Both sessions were identical (eight exercises, 3x10 repetitions), except that the R session was performed with an intensity between 5 and 7 in the OMNI-RES scale and the C session was performed without any load. Systolic blood pressure (BP), diastolic BP, heart rate, and rate-pressure product (RPP) were measured for 1 h after the interventions in the laboratory and during 24-h using ambulatory BP monitoring. Results After the R session, systolic BP (greatest reduction: -6 +/- 2 mmHg, P < 0.01) and RPP (greatest reduction: -888 +/- 286 mmHgxbpm; P < 0.01) decreased until 50 min after exercise. From the second hour until 23 h after exercise, BP, heart rate, and RPP product were similar (P > 0.05) between R and C sessions. BP load, nocturnal BP fall, and morning surge were also similar between R and C sessions (P > 0.05). Conclusion A single bout of resistance exercise decreased BP and cardiac work for 1 h after exercise under clinical conditions, and did not modify ambulatory cardiovascular variables during 24 h in patients with PAD.
