Niebauer J, Cooke JP. doi: 10.1152/physrev.00014.2016, 110. Enhanced endothelial production and secretion of ET-1, along with heightened sympathetic activity may represent key contributing factors in enhanced vasoconstriction of small diameter arteries and arterioles in the insulin-resistant state, thereby increasing systemic vascular resistance to blood flow and elevating arterial blood pressure. A chronic physical activity treatment in obese rats normalizes the contributions of ET-1 and NO to insulin-mediated posterior cerebral artery vasodilation. Hardy ST, Loehr LR, Butler KR, Chakladar S, Chang PP, Folsom AR, et al. (2015) 95:549–601. While this change may appear small, recent work shows that even a 1 mmHg reduction in systolic BP is associated with 20.3 fewer (blacks) or 13.3 fewer (whites) heart failure events per 100,000 person-years (62). However, in addition to NO-mediated reductions in resistance vascular tone, adaptive reductions in sympathetic nerve activity, prevention or reversal of arterial stiffening, and suppression of inflammation are also likely contributors to the blood pressure lowering effects of exercise, although the impact of exercise on these outcomes may be population specific (e.g., at-risk versus healthy adults) (72–74). 57. del Aguila LF, Claffey KP, Kirwan JP.

Whereas pathologic remodeling of the heart is associated with a reduction in oxidative energy production via fatty acid oxidation and more reliance on glucose utilization, mitochondrial biogenesis and capacity for fatty acid oxidation are enhanced following exercise (77, 78).

Other remaining questions are: can initiation of regular exercise, later in life, reverse the consequences of lifestyle choices made during earlier years of life (e.g., sedentarism, smoking), and whether the beneficial effects of exercise show circadian or seasonal dependence such that exercising during a particular time of day or a particular season imparts more benefit than under other conditions.

doi: 10.1097/00004872-199606000-00015, 64. In addition, some studies implicate hydrogen peroxide (H2O2)-mediated vasodilation in opposing exertion-induced arterial dysfunction in overweight obese adults after a period of exercise training (128, 129), suggesting enhanced contribution of NO-independent mechanisms to improved microvascular endothelial function with exercise. 58.

Possibly upstream of these metabolic changes, studies have also revealed a dominant role for IGF-1 and insulin receptor signaling, via the PI3K/Akt1 pathway leading to the activation of transcriptional pathways associated with protein synthesis and hypertrophy (80, 81). J Appl Physiol. This effect of exercise on cardiomyocyte contractile function may be related to alterations in the rise and decay rates of intracellular Ca2+ transients, possibly due to enhanced coupling efficiency between L-type Ca2+ channel-mediated Ca2+ entry and activation of subsarcolemmal ryanodine receptors (RyR; i.e., calcium-induced calcium release), and increased expression and activity of the sarcoendoplasmic reticulum Ca2+ ATPase (SERCA2a) and sodium-calcium exchanger (NCX) (88, 91, 92).

Studies in endurance runners show that the frequency of adverse cardiovascular events in marathoners is equivalent to that in a population with established CHD, suggesting that too much exercise may be detrimental . Studies in animal models of exercise suggest that increased physical activity can improve insulin sensitivity in adipose tissue, skeletal muscle, and endothelium (46–49), which are major contributors to systemic insulin resistance in individuals with type 2 diabetes. doi: 10.1152/jappl.2001.90.2.501, 128.

In addition to metabolic and molecular remodeling, exercise can also promote functional adaptation of the heart, which may ultimately increase cardiac output and reduce the risk of arrhythmia. C/EBPbeta controls exercise-induced cardiac growth and protects against pathological cardiac remodeling. Bonsignore MR, Morici G, Santoro A, Pagano M, Cascio L, Bonanno A, et al. During diabetes, selective inhibition of the PI3K-Akt-eNOS pathway, together with compensatory hyperinsulinemia leads to unmasking and stimulation of the MAPK-mediated production of endothelin-1 (ET-1) (36, 37), and vascular smooth muscle proliferation, which could contribute to atherosclerotic plaque development and peripheral artery disease (38, 39). A single session of low-intensity exercise is sufficient to enhance insulin sensitivity into the next day in obese adults. doi: 10.1002/dmr.5610010407, 45. Increasing levels of exercise over time were also found in this study to increase HDL from baseline (pre-exercise regimen) levels. During exercise, increases in cardiac stroke volume and heart rate raise cardiac output, which coupled with a transient increase in systemic vascular resistance, elevate mean arterial blood pressure (60). J Am Coll Cardiol. Frequent exercise is robustly associated with a decrease in cardiovascular mortality as well as the risk of developing cardiovascular disease.

However, the question remains as to how much exercise is optimal for cardiovascular health benefit. A novel action of insulin to increase nitric oxide release. Intense exercise is associated with the release of a variety of stress and inflammatory factors that are active on the bone marrow such as cortisol, IL-6, TNF-α, PMN elastase, and granulocyte colony stimulating factor (104–106). Size and blood flow of central and peripheral arteries in highly trained able-bodied and disabled athletes. Clinical studies have shown that exercise-trained individuals have improved systolic and diastolic function (85, 86), while results of studies using animal models of exercise show that endurance exercise promotes enhanced cardiomyocyte contraction-relaxation velocities and force generation (87–90).

This augmentation of heart size is primarily the result of an increase in the size of individual terminally differentiated cardiac myocytes (75). A recent study showing that adherence to a two-year, high-intensity exercise program decreases left ventricular stiffness in previously sedentary middle-aged participants (137) suggests that to some extent, beginning exercise, even late in life can be effective in reversing structural and functional changes in the cardiovascular system associated with aging and/or disease states such as heart failure with preserved ejection fraction. Despite the robust beneficial effects of physical activity and exercise on cardiovascular health, the processes and mechanisms by which frequent physical activity promotes cardiorespiratory fitness and decreases CVD risk remain unclear. Roberts WO, Schwartz RS, Garberich RF, Carlson S, Knickelbine T, Schwartz JG, et al. doi: 10.1056/NEJM198603063141003, 5. Other transcriptional pathways known to be activated by pathologic stimuli and cardiac hypertrophy, such as NFATc2, are decreased in exercise models (79, 84), suggesting that some signaling pathways activated during exercise-induced growth program may directly antagonize specific factors that promote pathological remodeling. doi: 10.1161/CIRCULATIONAHA.109.892224, 31.
