“…The experimental evaluation in seven patients with cardiovascular syndrome by Kopeć et al (2012) [98] also showed that after a 6-min walk, left ventricular volume and ET-1 levels increased. Author collective Boghabadi et al ( 2012) [99] found that after 3 months of aerobic exercise in elderly women, blood pressure and ET-1 level normalized. The authors report a positive training effect for problems with the cardiovascular system.…”

Elucidating the complex processes that determine the ability of the human body to adapt to specific intense training programs is critical to improving athletic performance in elite athletes. The present work aims to describe the main hemorheological changes as a result of physical exercises of different intensity, frequency, duration and modes of loading. Sport and physical exertion induce a hemorheological response of different nature and degree, structured in the present paper as follows: erythrocyte aggregation; change in the concentration of basic plasma components; changes in blood flow; changes in blood volume; changes in the endothelial cells of the vascular walls; changes in blood pressure; changes resulting from tissue hypoxia; interacting, different in nature hemorheological consequences. The studied and described original models of hemorheological response can contribute to a more successful adaptation of the training programs—In order to improve the health status of the participants and to optimize the sports form of the elite athletes. Physical loads of different frequencies, intensities and durations induce a different hemorheological response in athletes. The effect of “regular, moderate and properly dosed physical activity” during training is also strictly individual. This fact suggests approaching the training regime of each elite athlete personally, practicing specific to his preparation, well-chosen, balanced physical exercises. This will help to achieve the so-called state of hemorheological fitness. Extensive future research is needed to elucidate the cellular, tissue and molecular mechanism of hemorheological changes in blood, blood cells, and blood plasma. It is essential to study the vascular characteristics and biomechanical properties of blood under physical loads with different regimes and variable parameters, taking into account the individual, professional, biological and mechanical profile of each athlete.

“…Xiao et al reported that regular aerobic exercise decreases ET, increases NO and reduces the ET/NO ratio (19). However, Boghrabadi et al reported that aerobic exercise training causes a significant increase in ET-1 levels of young, middle-aged and old women (20). Radovanovic et al showed that four weeks of pre-competition training had no effect on oxidative factors such as MDA and NO in 10 male judokas (mean age: 20±1.3 years; sport experience: 11±3.4 years) (21).…”

Background and Objectives: Oxidative stress is a common mediator in pathogenicity of established cardiovascular risk factors. The purpose of this study was to determine effects of selected aerobic training on some oxidative stress indicators in sedentary elderly women. Methods: In this quasi-experimental study, 21 participants (age range: 60-70 years) were selected by convenience sampling and then randomly assigned to an exercise group (n=11) and a control group (n=10). Aerobic exercise was performed at 50-70% of heart rate reserve for 45-60 minutes per session, three sessions a week, for eight weeks. Blood samples were taken at baseline and 24 hours after the last training session. Within-group and between-group differences were assessed using paired sample t-test and independent t-test, respectively. Statistical significance level was set at 0.05. Results: Weight, body mass index and body fat percentage decreased significantly after the exercise intervention (P<0.05). We also noted a significant reduction in endothelin-1 levels in both groups (P<0.05). Nitric oxide increased significantly after the eight-week exercise training (P<0.05). Moreover, serum 8-hydroxydeoxyguanosine levels decreased significantly in the exercise group (P<0.05). No significant change was observed in malondialdehyde and urinary 8-hydroxydeoxyguanosine levels in both groups. The result also showed a significant difference in subjects' weight and in nitric oxide and 8hydroxydeoxyguanosine levels between the two groups (P<0.05). Conclusion: It seems that regular aerobic exercise at moderate intensity can improve antioxidative capacity and reduce the risk of cardiovascular disease in elderly women.
