Recent work from cardiovascular cohorts shows that sustained physical activity is associated with a more favorable inflammatory marker profile, decreases heart failure risk, and improves survival at 30 years follow-up in individuals with coronary artery disease (8–10). Exercise-induced changes in glucose metabolism promote physiological cardiac growth. Training induces nonuniform increases in eNOS content along the coronary arterial tree. In contrast, increased myocyte size in physiological hypertrophy is associated with the upregulation of depolarizing and repolarizing currents, which may be protective against abnormal electrical signaling in the adapted heart (95, 96).

Am J Cardiol. While our understanding of the precise cellular and molecular mechanisms involved in the enhancement of insulin signaling following exercise has been hampered by inconsistent results across species and exercise protocols, it appears that exercise conditioning is associated with adaptive remodeling in the expression or regulation of one or more components of the insulin receptor/insulin receptor substrate (IRS)/PI3K/Akt signaling cascade (50–52). Front Biosci. This includes structural adaptations consisting of an expansion in the density of intramyocardial arterioles and capillaries as well as enhanced microvascular collateral formation (121–124). Here is how you can design an effective cardiorespiratory endurance program. doi: 10.1111/j.1365-2362.2003.01263.x, 34. doi: 10.1161/CIRCRESAHA.107.170050, 95. doi: 10.1161/CIR.0000000000000485, PubMed Abstract | CrossRef Full Text | Google Scholar, 3. This may be partly due to adaptation of the endothelium to the complex interplay of recurrent variations in hemodynamic stresses and vasodilatory stimuli of exercise. Physical training and insulin sensitivity. Frequent exercise is robustly associated with a decrease in cardiovascular mortality as well as the risk of developing cardiovascular disease. Cardiovascular endurance is also frequently called cardio-respiratory endurance, cardiovascular fitness, aerobic capacity, aerobic fitness or is sometimes more broadly termed endurance although endurance may also refer to the ability of the muscle to do repeated work without fatigue. That exercise stimulates NO production is supported by animal studies. doi: 10.2337/diabetes.52.10.2562, 40.

A recent investigation also showed that individuals who maintain very high levels of physical activity (~3 times recommended levels) have higher odds of developing CAC, particularly in white males (134). Circ Res. In addition, early studies aimed at determining effects of physical activity on low density lipoprotein (LDL) levels did not test the dose-dependence of exercise. Laughlin MH, Pollock JS, Amann JF, Hollis ML, Woodman CR, Price EM. Gordon T, Castelli WP, Hjortland MC, Kannel WB, Dawber TR. Chronic exercise alters contractility and morphology of isolated rat cardiac myocytes.

J Am Coll Cardiol. 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. (2001) 50:495–508. Intensity. J Appl Physiol. Physical inactivity increases oxidative stress, endothelial dysfunction, and atherosclerosis. Any activity is better than none at all. To improve both cardiovascular fitness and to decrease body fat or maintain body fat at optimum levels, you should exercise (cardiovascularly) at least three days a week. 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. Morici G, Zangla D, Santoro A, Pelosi E, Petrucci E, Gioia M, et al. Copyright © 2018 Nystoriak and Bhatnagar. Effects of endurance training on gene expression of insulin signal transduction pathway. Lewis GF. However, a study of subjects with mild to moderate dyslipidemia, randomized into high amount/high intensity (23 kcal/kg/wk, jogging), low amount/high intensity (14 kcal/kg/wk, jogging), and low amount/moderate intensity (14 kcal/kg/wk, walking) exercise training groups over a 6 months period, found a dose-dependent effect of exercise on plasma levels of LDL, triglycerides, and large particle, very low density lipoprotein (VLDL) (15). 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). Regular exercise training prevents aortic valve disease in low-density lipoprotein-receptor-deficient mice. Training Frequency ¨ Training frequency refers to the number of training sessions conducted per day or per week. Throughout the text, we distinguish between these two types of activities to the extent possible. Med Sci Sports Exerc.

In contrast, other studies report greater plaque stability due to calcification in exercisers, thus indicating that with higher levels of physical activity, plaque quality may be favorably impacted to lower the risk of cardiovascular events, despite a higher incidence of plaques and normal CAC scores (135, 136). Prospective Cardiovascular Munster study. These changes may at least partially depend on upregulation of the Na+/H+ antiporter and altered regulation of intracellular pH. Goodyear LJ, King PA, Hirshman MF, Thompson CM, Horton ED, Horton ES. Cardiovascular endurance can be improved by doing several types of aerobic conditioning. doi: 10.1016/0002-9343(77)90874-9, 17. Houmard JA, Shaw CD, Hickey MS, Tanner CJ. Although HPCs appear to modestly decline in the period immediately following an exercise session in conditioned runners, one study found that circulating CD34+ hematopoietic progenitor cell counts were 3- to 4-fold higher in runners vs. non-runners at baseline (102), which may represent an adaptive response that facilitates tissue repair. Am J Prev Med. doi: 10.1172/JCI10762, 32. doi: 10.1161/CIRCULATIONAHA.117.030617, 138. As the levels of initial fitness improve, the changes in aerobic power decreases regardless of the intensity, frequency or duration of exercise. However, the question remains as to how much exercise is optimal for cardiovascular health benefit.

In contrast, aorta from sedentary mice kept in normal housing conditions exhibit increased vascular lipid peroxidation and superoxide levels, which may contribute to endothelial dysfunction and lesion formation, when compared with mice subjected to 6 weeks of voluntary wheel running (29). doi: 10.1097/00005768-200107000-00008, 86. Regular, but not intermittent, physical activity in high cholesterol diet-fed LDLR-null mice has also been found to rescue aortic valve endothelial integrity, reduce inflammatory cell recruitment, and prevent aortic valve calcification (30), which raises the possibility that exercise may reduce the development and progression of degenerative aortic valve disease.

Sustained physical activity, not weight loss, associated with improved survival in coronary heart disease. Activation of Cited4 has been found to be necessary for exercise-induced cardiac hypertrophy, and cardiac-specific overexpression of the gene is sufficient to increase heart mass and protect against ischemia/reperfusion injury (83). It is important to know your FITT Principles so that you gain health benefits for your heart. Thus, further research is required to elucidate how certain exercise regimens can promote tissue-specific adaptations in insulin-signaling and how these pathways may be targeted to reverse insulin-resistance and associated cardiovascular complications of diabetes. A number of studies have shown that individuals with insulin-dependent and non-insulin-dependent diabetes mellitus have improved sensitivity to insulin and improved glycemic control after exercise training (42–44). doi: 10.1161/01.CIR.0000074229.93804.5C, 28.
