Increases blood flow and decreases chances of stroke.
1. Promoting cardiovascular health
A cardiovascular exercise challenges the heart to get more active, strengthening its muscles and promoting efficient pumping of blood throughout the body.
2. Aiding weight loss
Cardiovascular exercises can be a great addition to your weight loss journey if looking to lose weight.
3. Strengthening the immune system
A strong immune system is essential to help you recover from an illness, protect you from seasonal colds and flu, detect and fight infection, promote restful sleep and reduce fatigue.
4. Promoting brain function
Aerobic activity increases blood flow to the brain. This has a physiological effect and may help promote cognitive functions.
5. Preventing inflammation
Today’s most chronic conditions started as an inflammation that ended up repeatedly occurring, creating a conducive environment for a disease to develop. That’s why reducing your inflammatory markers is very important if you want to stay healthy.
6. Boosting mood
Exercise is a natural mood booster and can profoundly benefit anxiety, depression, and ADHD. When you engage in aerobic activities, your body produces hormones and other chemical messengers like endorphins which are natural mood boosters.
7. Regulating blood glucose
Engaging in moderately-intense cardiovascular activities such as walking, swimming, or jogging, causes you to breathe harder and your heart to beat faster. This also causes your muscle to use more glucose as a source of energy, and over time, this may increase glucose uptake into the cells, helping you maintain healthy blood glucose levels.
How does the heart respond to exercise?
During exercise, the heart is subjected to intermittent hemodynamic stresses of pressure overload, volume overload, or both. To normalize such stress and to meet the systemic demand for an increased blood supply, the heart undergoes morphological adaptation to recurrent exercise by increasing its mass, primarily through an increase in ventricular chamber wall thickness. This augmentation of heart size is primarily the result of an increase in the size of individual terminally differentiated cardiac myocytes (75). Adaptive remodeling of the heart in response to exercise typically occurs with preservation or enhancement of contractile function. This contrasts with pathologic remodeling due to chronic sustained pressure overload (e.g., during hypertension or aortic stenosis), which can proceed to a loss of contractile function and heart failure (76).
How does cardiovascular disease affect the world?
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. In the United States, CVD accounts for ~600,000 deaths (25%) each year (1, 2), and after a continuous decline over the last 5 decades, its incidence is increasing again (3). Among the many risk factors that predispose to CVD development and progression, a sedentary lifestyle, characterized by consistently low levels of physical activity, is now recognized as a leading contributor to poor cardiovascular health. Conversely, regular exercise and physical activity are associated with remarkable widespread health benefits and a significantly lower CVD risk. Several long-term studies have shown that increased physical activity is associated with a reduction in all-cause mortality and may modestly increase life expectancy, an effect which is strongly linked to a decline in the risk of developing cardiovascular and respiratory diseases (4). Consistent with this notion, death rates among men and women have been found to be inversely related to cardiorespiratory fitness levels, even in the presence of other predictors of cardiovascular mortality such as smoking, hypertension, and hyperlipidemia (5). Moreover, better fitness levels in both men and women can partially reverse the elevated rates of all-cause mortality as well as CVD mortality associated with high body mass index (6, 7). 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).
How does the resistance arterial network adapt to exercise?
The resistance arterial vascular network also undergoes functional and structural adaptation to exercise (109). During acute exercise, small arteries and pre-capillary arterioles that supply blood to the skeletal muscles must dilate to increase blood flow through the release of vasodilatory signals (e.g., adenosine, lactate, K+, H+, CO2) from active surrounding muscle (110–112). Repeated exercise leads to an adaptive response in skeletal muscle arterioles that includes increased vascular density coupled with greater vasodilatory capacity, such that enhanced perfusion can occur after conditioning (113–116). 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. Endothelial synthesis of NO is greatly increased at rest and during exercise in conditioned individuals/animals (117). A similar adaptive response to exercise has also been noted in the coronary vasculature, which must dilate to meet the increased metabolic demands of the myocardium (118). Exercise-trained humans and animals demonstrate reduced myocardial blood flow at rest, which may reflect a reduction in cardiac oxygen consumption primarily as a result of lower resting heart rate (119, 120). However, a large body of evidence suggests that multiple mechanisms converge to enhance the ability of the coronary circulation to deliver a greater supply of oxygen to the conditioned myocardium during exercise. 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). Additionally, like skeletal muscle arterioles, coronary arterial network enhances its responsiveness to vasoactive stimuli via a number of distinct mechanisms including, but not limited to, augmentation of endothelial NO production, altered responsiveness to adrenergic stimuli, or changes in the metabolic regulation of vascular tone (125–127). 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. Collectively, these adaptations may act to support enhanced myocardial function and increased cardiac output during repeated exercise, and increased total body oxygen demand following exercise conditioning. Further advancement of our understanding of how blood flow is improved in response to exercise could lead to novel therapeutic strategies to prevent or reverse organ failure in patients resulting from inadequate blood flow.
What causes electrical instability in the heart?
During pathologic remodeling of the heart, electrical instability can result from a lack of upregulation of key cardiac ion channel subunits associated with action potential repolarization relative to an increase in myocyte size (94). 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). For example, cardiac myocytes isolated from mice after 4 weeks of swim training were found to have elevated outward K+current densities (i.e., Ito,f, IK,slow, Iss, and IK1) and increased expression of underlying molecular component Kv and Kir subunits in parallel with increases in total protein levels (96). Interestingly, a follow up study found that while increases in K+channel subunit expression following exercise training requires PI3K, these changes occur independently of Akt1 and hypertrophy (97).
What is the effect of shear forces on skeletal muscle?
Contributing to this effect, shear forces, as well as released metabolites from active skeletal muscle during exercise, signal the production and release of nitric oxide (NO) and prostacyclin from the vascular endothelium, which promotes enhanced vasodilation via relaxation of vascular smooth muscle cells (66).
Does plaque quality affect cardiovascular risk?
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).
Does exercise increase cardiac output?
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. 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 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). In addition, the sensitivity of the cardiomyocyte contractile apparatus may also become more sensitive to Ca2+, thus producing a greater force of contraction at a given [Ca2+]i, following exercise, (93). These changes may at least partially depend on upregulation of the Na+/H+antiporter and altered regulation of intracellular pH.
How does exercise affect your health?
It’s interesting how just 30 minutes of activity a day can improve your mood, lower your risk of heart disease, give you more energy, and help you sleep better. While we have discussed the physical and psychological effects of exercise on your health, Dr. Woods acknowledges the one plus that resonates with most patients: empowering your role in your health. “People don’t want to take pills, and if I tell them, there’s something that they can do to reduce the possibility that they will need to be on medications, that is a powerful motivator. In addition to reducing the risk of heart disease or health conditions, what is empowering to patients is knowing that what they do matters. Exercise can be a social activity for people as well, which is incredibly important for your lifestyle health too.”
Why does exercise make you feel good?
Exercise is mother nature’s painkiller because it releases neurochemicals called endorphins. These are natural hormones associated with feelings of euphoria and well-being that are delivered during aerobic exercise like running but also while swimming, cycling, or rowing. When your heart is pumping blood to all organs and parts of your body, endorphins are released to combat stress. This is why you “feel good” after a long run or bike ride. Your body is helping your muscles recover and rebuild.
How does cardio work?
Our heart beats about 10,000 times a day, making it one of the most active organs in the body. The goal of cardio exercise is to increase our heart rate from 40 to 80 percent of our maximum heart rate. “Essentially, you’re trying to increase your blood flow to your muscles. Increasing oxygen delivery and your body does that in a variety of ways. Certainly, your heart rate increases. The strength of the heart contraction increases. Your blood pressure, respiratory rate, and oxygen exchange all build trying to meet the energy needs of the muscles when you’re exercising,” Dr. Woods added. This is how cardio burns fat by causing us to breathe hard and sweat. Regular cardio exercise can help people with normal blood pressure maintain healthy blood pressure levels, allowing our heart to pump more efficiently and protecting our blood vessels.
Why is exercise considered a pain killer?
