Bullet Point

The effects of exercise-heat acclimation (HA), in individuals with type 2 diabetes (T2D), on heart rate variability (HRV) remains unclear. We assessed electrocardiogram recordings during exercise-heat stress, in middle-aged-to-older individuals (50-70 years) with (n=6) and without (n=8; CON) T2D, before and after 7-days exercise HA. Exercising heart rate was reduced (CON, -9 ±5 bpm; T2D, -14 ±9 bpm) yet HRV was unresponsive. Given the negative correlations between diminished HRV and cardiac risk, further research is warranted. <b>Novelty bullet point:</b> Our observations indicate that exercise-heat acclimation may not effectively attenuate the deviation toward reduced overall HRV and unfavourable cardiac autonomic modulation in individuals with T2D.

And Control

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.

Chronic Hyperglycemia

IntroductionType 2 diabetes (T2D) is characterized by a metabolic disorder that elevates blood glucose concentration. Chronic hyperglycemia has been associated with several complications in patients with T2D, one of which is cardiac autonomic dysfunction that can be assessed from heart rate variability (HRV) and heart rate recovery (HRR) response, both associated with many aspects of health and fitness, including severe cardiovascular outcomes.ObjectiveTo evaluate the effects of T2D on cardiac autonomic modulation by means of HRV and HRR measurements.Materials and MethodsThis study has an observational with case-control characteristic and involved ninety-three middle-aged adults stratified into two groups (control group - CG, n = 34; diabetes group - DG, n = 59). After signing the free and informed consent form, the patients were submitted to the evaluation protocols, performed biochemical tests to confirm the diagnosis of T2D, collection of R-R intervals for HRV analysis and cardiopulmonary effort test to quantify HRR.ResultsAt rest, the DG showed a reduction in global HRV (SDNN= 19.31 ± 11.72 vs CG 43.09 ± 12.74, p &lt; 0.0001), lower parasympathetic modulation (RMSSD= 20.49 ± 14.68 vs 52.41 ± 19.50, PNN50 = 4.76 ± 10.53 vs 31.24 ± 19.24, 2VD%= 19.97 ± 10.30 vs 28.81 ± 9.77, p &lt; 0.0001 for both indices) and higher HRrest when compared to CG. After interruption of physical exercise, a slowed heart rate response was observed in the DG when compared to the CG. Finally, a simple linear regression showed that fasting glycemia was able to predict cardiac autonomic involvement in volunteers with T2D.ConclusionPatients with T2D presented lower parasympathetic modulation at rest and slowed HRR after physical exercise, which may be associated with higher cardiovascular risks. The findings show the glycemic profile as an important predictor of impaired cardiac autonomic modulation.

AbstractThis study aimed to assess whether obesity and/or maximal exercise can change 24 h cardiac autonomic modulation and blood pressure in young men. Thirty-nine men (n: 20; 21.9±1.8 kg·m−2, and n: 19; 32.9±2.4 kg·m−2) were randomly assigned to perform a control (non-exercise) and an experimental day exercise (after maximal incremental test). Cardiac autonomic modulation was evaluated through frequency domain heart rate variability (HRV). Obesity did not impair the ambulatory HRV (p>0.05), however higher diastolic blood pressure during asleep time (p=0.02; group main effect) was observed. The 24 h and awake heart rate was higher on the experimental day (p<0.05; day main effect), regardless of obesity. Hypotension on the experimental day, compared to control day, was observed (p<0.05). Obesity indicators were significantly correlated with heart rate during asleep time (Rho=0.34 to 0.36) and with ambulatory blood pressure(r/Rho=0.32 to 0.53). Furthermore, the HRV threshold workload was significantly correlated with ambulatory heart rate (r/Rho=− 0.38 to−0.52). Finally, ambulatory HRV in obese young men was preserved; however, diastolic blood pressure was increased during asleep time. Maximal exercise caused heart rate increase and 24h hypotension, with decreased cardiac autonomic modulation in the first hour, regardless of obesity.
