Being Physically Active…move your body more…pursue a well-rounded exercise plan that fits your lifestyle
Hundreds of studies have shown that exercise lowers your risk for serious health problems, including heart disease, diabetes, stroke, high blood pressure, and certain forms of cancer. What’s more, physical exercise eases arthritis and preserves independence while trimming your waistline. Put simply, exercise helps you feel better, look great, and live a longer, more joyful and satisfying life.
Centers for Disease Control and Prevention guidelines recommend exercising moderately for 150 to 300 minutes or 75 to 150 minutes of vigorous activity — and that the higher number should be the target. Exercise strengthens your heart muscle, lowers your blood pressure and cholesterol, and burns calories. It can also enhance your mood.
Aerobic exercise can improve the way your heart and other muscles use oxygen. The right blend of exercises for you incorporates aerobic workouts (including walking), as well as stretching and strength-building / resistance exercises.
Exercise is the best investment you can make for your health.
“It is never too late to reverse how you look and feel, and develop the mindset of how you do it. Day in and day out, if you want to live longer and live better, you need a clear and basic understanding that the outcome of your journey is the sum of its steps.” Strauss Zelnick, Becoming Ageless
Researchers are learning just how exercise fights cardiovascular disease. What they know is that exercise improves the efficiency of the muscles that it puts to work, including the heart. It improves blood flow to the heart muscle and reduces the risk of abnormal pumping rhythms.
Studies have evaluated exercise and health in men and women of diverse ethnic and socioeconomic backgrounds. Although the details vary, the vast majority agree that regular exercise is associated with a sharp reduction in heart attacks and cardiac deaths; most cite protection in the range of 35% to 55%.
Furthermore, studies show that modest exercise, such as walking about two miles a day or burning about 1,000 calories a week, can provide enormous protection against heart disease. And exercise helps even people who don’t start exercising until later in life, as well as patients who don’t start until they suffer a heart attack. In fact, a meta-analysis of 48 trials involving nearly 9,000 cardiac patients found that exercise-based rehabilitation reduced the patients’ risk of dying from heart disease by 26%.
Aerobic exercise helps your heart and other muscles better use oxygen.
In addition, exercise lowers LDL (“bad”) cholesterol and triglyceride levels while boosting HDL (“good”) cholesterol. It also reduces body fat, insulin levels, and the risk of diabetes — all cardiac risk factors. Regular exercise improves the body’s defenses against artery-blocking blood clots and quiets the vascular inflammation that fuels the fire of atherosclerosis.
Atherosclerosis is the accumulation of pockets of cholesterol-rich gunk inside the arteries, according to Harvard Health. These pockets, called plaque, can limit blood flow through arteries that nourish the heart — the coronary arteries — and other arteries throughout the body. When a plaque breaks apart, it can cause a heart attack or stroke.
A healthy lifestyle which includes exercise goes a long way to preventing cardiovascular disease. Aerobic and resistance exercise can prevent heart-harming trends, like high blood pressure or high cholesterol, before they can cause damage.
“A man is as old as his arteries.” Thomas Sydenham, English physician
A regular exercise program has a major effect on the health of your arteries. Every artery has three layers in its wall. The endothelium is the innermost of the artery’s three layers and is composed of a thin layer of endothelial cells that are in direct contact with the bloodstream. It produces nitric oxide, which helps keep the artery open and healthy. Plaques have the opposite effect.
Endothelial cells have a crucial role in vascular health, and exercise has an important effect on endothelial cells. Among other things, endothelial cells produce nitric oxide. Tiny amounts of nitric oxide produced by your endothelial cells are a boon to your circulation.
This nitric oxide has two crucial functions. It keeps the arterial lining smooth and slippery, preventing white blood cells and platelets from latching on and causing damaging inflammation and artery-blocking blood clots. In addition, it relaxes the smooth muscle cells of the artery wall’s middle layer, preventing spasms and keeping arteries open.
Invest in yourself! Exercise is the best investment you can make for your health
Cardiovascular and chronic diseases are not inevitable as we get older. Although, more research is needed, the evidence suggests that regular exercise can reduce the risk of heart disease and other common chronic health problems as you age.
