“…17 In addition, there is evidence that aerobic and resistance exercise has a positive effect on HRV and autonomic function in high-risk populations, which positively affects the cardiovascular prognosis of these patients. 18 As the study sample contains only physically inactive women, and thus the relationship between physical exercise and autonomic modulation cannot be observed. Despite the absence of a significant correlation between the EFL and HRV scores, it was possible to observe that an increase in the AFO, AFL and EFT score favors the improvement of the autonomic heart rate modulation, and represent an important behavioral change regarding the pattern of physical activity habitual.…”

The objective of the study was to analyze the relationship between the habitual physical activity pattern and the autonomic heart rate modulation in postmenopausal women with Type 2 Diabetes. The sample of 44 postmenopausal women aged 51 to 82 years, diagnosed with Type 2 Diabetes and sedentary. The usual physical activity (AFH) was estimated by the Baecke questionnaire, which evaluates occupational physical activities (AFO), physical exercise and laser (EFL), physical activity of leisure and locomotion (ALL) and local physical activity (AFT)). Autonomic modulation was assessed by frequency variability analysis (HRV) at 20 minutes rest in the supine position. The AFO score showed a positive and significant correlation with MeanRR (ms), RMSSD (ms), HF(ms 2 ) and SD1 (ms) values, indicating that the increase in occupational physical activity correlates with increased vagal and Reduction in resting heart rate. The AFL score showed a positive correlation with the values of HF (nu) and negative with values of LF (nu), showing that an increase in AFL correlates with reduction of modulation The AFT score had a positive correlation with the HF (nu) value and negatively with the LF/ HF value, indicating that an increase in the standard of total habitual physical activity contributes to a Increased parasympathetic modulation and an improvement in the sympatho-vagal ratio. Although the results do not present direct correlation with the score that represents the practice of Physical Exercise systematizes with improvements of the autonomic modulation, the physical exercise contributes to a higher AFT score, and in this way may be related to the increase of the parasympathetic activity, reduction of the Sympathetic activity and improvement of the sympatho-vagal balance.

“…Although lipolysis is a metabolic process stimulated by catecholamines during physical activity and therefore higher amounts of fatty acids available to be oxidized [39][40][41], animals of the trained group increased carbohydrate oxidation compared with the control group, suggesting greater balance in the oxidation of energy substrates. Melanson et al [42] showed that the oxidation of lipids in individuals submitted to aerobic activity did not differ statistically from those physically inactive.…”

“…Vedala et al [50] and Vougari et al [39] propose that regular exercise has been adopted as a strategy to reduce the harmful effects caused by poor life style and heart attacks, both associated with metabolic disorders. The basis for this strategy is evidenced mainly by the reduction of dyslipidemia, such as reduced levels of triglycerides, total cholesterol and low density lipoproteins (LDL-cholesterol) and increase high density lipoprotein (HDL-cholesterol) cholesterol [50,51].…”

Occidental life styles, including physical inactivity, are related to risk of developing heart diseases. To prevent or even mitigate these effects, the frequent recommendation has been the practice of physical exercise as a measure of therapeutic interaction in preventive medicine and rehabilitation. Thus, our study was carried out to evidence the effects of aerobic physical exercise regularly practiced, through swimming, calorimetry, lipid profile, and oxidative stress in myocardium. Thirty-two Winstar rats, males, 75 days old were used. Animals were divided into two groups: C (n=8) as the control, which received food and water ad libitum and TR (n=8) as the trained group received the same treatment as C and animals in this group were submitted to swim. Swimming was used as a model of exercise with moderate intensity training for eight weeks. The experimental design was completely randomized with 16 treatments and eight replications, with a significance level of 5% probability. Calorimetry shows lower carbohydrate oxidation and increased lipid oxidation in C when compared with TR. The trained group had higher glucose, higher HDL-cholesterol and lower accumulation of triglycerides, and verified the protective effect in cardiac tissue. Thus, we can conclude that the swimming protocol was effective in controlling deleterious effects caused by poor habits on the myocardium.

“…On the other hand, autonomic cardiac modulation manipulates human body both physiologically and psychologically, e.g., circulation in brain. Earlier work has shown that autonomic cardiac modulation has a strong relationship with human emotion state [2], the motor function of human body [3], sleep [4], etc.…”
