Abstract

The Heart Rate Variability (HRV) is a noninvasive technique to assess the functioning of the autonomic nervous system. An enlarged Waist Circumference (WC) is an indicator of obesity, therefore a predictor of increased risk of cardiovascular disease. OBJECTIVES: To analyze the changes of autonomic response in two groups of young women, obese and non-obese, classified using the WC. MATERIALS AND METHODS: The study included 12 female volunteers divided in a balanced way in obese and non-obese, who underwent an incremental treadmill protocol. The HRV parameters analyzed were SDNN, RMSSD, HF, LF and LF/HF ratio, determined by the R-R interval registry obtained by a Polar S810 heart rate monitor and analyzed by Kubios HRV software, version 2.0. RESULTS: There were no differences observed between groups in the HRV parameters after the first minute of active recovery, checking, however, a tendency to higher average LF values after 20 minutes of passive recovery in the obese women group. DISCUSSION: Opposing some literature that refers to lower HRV in obese women, this study’s results point to a similar behavior after the first minute of active recovery in both groups. However, it is noticed an increase in parasympathetic influence in the group of non-obese, after a 20 minutes passive recovery, this behavior may be constituted with potential in predicting the cardiovascular risk. CONCLUSION: We conclude that the young obese women group has lower heart rate variability after 20 minutes of passive recovery, when compared with a normoponderal group.
