ABSTRACT
OBJECTIVE:
To analyze the effect of a single bout of resistance exercise on cardiac autonomic modulation in patients with peripheral artery disease.METHODS:
Fifteen patients with peripheral artery disease (age 58.3±4.0 years) underwent the following sessions in a random order resistance exercise (three sets of 10 repetitions of the six resistance exercises with a workload of 5-7 in the OMNI-RES scale) and control (similar to the resistance session; however, the resistance exercises were performed with no load). The frequency domain (low frequency, high frequency and sympathovagal balance) and symbolic analysis (0V, 1V and 2V patterns) of heart rate variability were obtained before and until one hour after the interventions.RESULTS:
After the resistance exercise and control sessions, similar increases were observed in the consecutive heartbeat intervals (control 720.8±28.6 vs. 790.9±34.4 ms; resistance exercise 712.9±30.1 vs. 756.8±37.9 ms; p<0.05) and in the pattern of the symbolic analysis with no variation (0V) (control 25.1±3.5 vs. 33.4±4.1%; resistance exercise 26.1±3.2 vs. 29.7±3.5%; p<0.05) until 50 min after both interventions. The pattern of two variations (2V) decreased similarly (control 11.2±2.1 vs. 8.3±2.1%; resistance exercise 9.5±1.7 vs. 7.8±1.7%; p<0.05). In contrast, the pattern of one variation (1V), the low and high frequency bands and sympathovagal balance did not change after the interventions (p>0.05).CONCLUSION:
A single bout of resistance exercise did not alter cardiac autonomic modulation in patients with peripheral artery disease. .
