OBJECTIVE: To analyze the chronic effect of physical exercise on the heart rate variability (HRV) in obese postmenopausal women. METHODS: Twenty-eight postmenopausal obese women aged 45 to 65 years old were evaluated, the HRV collection was done using the RS800 polar clock and the analysis was performed in the Kubios HRV 3.0.0 program. The volunteers were divided into Control Group (CG) n = 6 and Training (GT) n = 22. The volunteers of the GT group underwent 12 weeks of aerobic training, 3 times a week for 40 minutes. Anthropometric measurements and autonomic heart rate modulation were performed by HRV using time domain indexes (mean RR, SDNN, rMSSD, pNN50) and frequency (LF, HF and LF / HF) before and after training. RESULTS: Postmenopausal obese women submitted to aerobic training had a statistically significant increase in HRV in the SDNN index (p = 0.028), a decrease in the same index in the CG and a decrease in the Hip Waist Ratio in the GT after training compared to the pre training. CONCLUSION: Based on the results of the study, we demonstrated that 12 weeks of aerobic training increased the HRV index and decreased WHR in obese postmenopausal women.
