Effect of 12 weeks of a hydrogymnastic program on blood pressure, heart rate variability and body composition in obese women
Abstract
The present study aimed to verify the effect of 12 weeks of water aerobics program on blood pressure, cardiac autonomic control and body composition in obese women. Eleven female subjects (50.55 ± 5.09 years; 82.31 ± 7.91 kg; 156.36 ± 6.86 cm) obese took part of this study. Measurements of anthropometric variables, body composition, systolic and diastolic blood pressure and heart rate variability were assessed pre and post-intervention. The water aerobics program consisted of 12-week (2 times/week). It was found significant difference for waist circumference (p = 0.049), waist-to-hip ratio (p = 0.009), body fat percentage (p = 0.025) and lean mass percentage (p = 0.025). In addition, there was significant difference to systolic blood pressure after intervention (p = 0.029). Moreover, it was not find significant difference for the HRV indices (RRi, SDNN and RMSSD) after the intervention (p = 0.259; P = 0.158; p = 0.091; respectively). In conclusion, 12 weeks of water aerobics program improved the systolic blood pressure, anthropometric variables and body composition, but there was not changes on heart hate variability in obese women.
