Exercício aquático e modulação autonômica cardíaca de mulheres na pós-menopausa com diabetes tipo 2

Abstract

Objective: Investigating the effect of 12 weeks of an aquatic exercise program on cardiac autonomic modulation by heart rate variability index of postmenopausal women with type 2 diabetes mellitus (T2DM). Methods: A randomized clinical trial was performed in 25 women aged 51 to 83 years, divided into exercise group (EG) (n = 13) submitted for 12 weeks to two weekly sessions of 50 minutes each, and control group (CG) (n = 12) without exercise. Results: Regarding cardiac autonomic modulation significant interaction was observed for TINN values (ms), indicating a slight increase in EG, but mostly a reduction in CG. The regression analysis also pointed effect of aquatic exercise on reducing the LF/HF ratio, after controlling for covariates diastolic blood pressure and dyslipidemia. Conclusion: The aquatic exercise had a significant effect on the reduction of cardiovascular risk, mainly in relation to glycemia and abdominal obesity, which may represent a protective effect of exercise in the progression of autonomic dysfunction, but its effect on autonomic modulation seems to depend on a greater volume and time with aquatic exercise.Keywords: diabetes, women, menopause, autonomic nervous system.

Effect of aquatic exercise on cardiovascular fitness in people with type 2 diabetes mellitus: a systematic review and meta-analysis

“…12 studies [9][10][11][12][13][14][15][16][17][18][19][20] involving 320 participants were included in the final analysis. The basic characteristics of each study were shown in Table 1.…”

“…There were ten studies [9][10][11][12][13][14][15][16][17]20] about the effect of AE on RHR. Three [13,17,20] were designed as AE vs LE, four [9,11,14,16] designed as AE vs Ctrl, and three [10,12,15] were pre-/ post-AE design. RHR was declined in post-AE when compared to pre-AE (WMD= -5.88, 95 %CI -6.88 to 5 and 6).…”
