Cardiovascular health relates to the health of the heart and blood vessels. It also relates to the health of organs that are critically dependent on a strong blood supply. Maintenance of cardiovascular health and prevention of cardiovascular disease can only be resolved with lifestyle changes and not with drugs. Drugs can only ever be used for very short-term relief due to their dangerous side effects. One of the major cardiovascular diseases are Coronary heart disease, Stroke, Heart failure ,Peripheral vascular disease.The main underlying causal mechanism of cardiovascular disease is atherosclerosis, a process caused by local inflammation resulting in a protective build-ups of fat, cholesterol and other substances in the inner lining of the arteries. It is most serious when it affects the blood supply to the heart (causing angina or heart attack) or to the brain (causing a stroke). The major, preventable risk factors for cardiovascular disease are Tobacco/Smoking, Chronic inflammation, High blood pressure, High blood cholesterol, Insufficient or too much physical activity, Stress/worry, Overweight and obesity, Poor nutrition ,Diabetes.Regular exercise is an important way to lower your risk of heart disease. Exercising for 30 minutes or more on most days can help you lose weight, improve your cholesterol, and even lower your blood pressure by as many as five to seven points. A sedentary lifestyle, where your job and your leisure activities involve little or no physical activity, doubles your risk of dying from heart disease. This is similar to the increased risk you'd have if you smoked, had high cholesterol, or had high blood pressure.
Cardiovascular fitness is the ability of the heart and lungs to supply oxygen-rich blood to the working muscle tissues and the ability of the muscles to use oxygen to produce energy for movement. This type of fitness is a health-related component of physical fitness that is brought about by sustained physical activity. A person’s ability to deliver oxygen to the working muscles is affected by many physiological parameters, including heart rate, stroke volume, cardiac output, and maximal oxygen consumption. Understanding the relationship between cardiorespiratory endurance training and other categories of conditioning requires a review of changes that occur with increased aerobic, or anaerobic capacity. As aerobic/anaerobic capacity increases, general metabolism rises, muscle metabolism is enhanced,hemoglobin rises, buffers in the bloodstream increase, venous return is improved, stroke volume is improved, and the blood bed becomes more able to adapt readily to varying demands. Each of these results of cardiovascular fitness/cardiorespiratory conditioning will have a direct positive effect on muscular endurance, and an indirect effect on strength and flexibility. To facilitate optimal delivery of oxygen to the working muscles, the person needs to train or participate in activities that will build up the energy stores needed for sport. This is referred to as metabolic training. Metabolic training is generally divided into two types:aerobic and anaerobic. Adults need at least: 2 hours and 30 minutes (150 minutes) of moderate-intensity aerobic activity (i.e., brisk walking) every week and muscle -strengthening activities on 2 or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders, and arms).1 hour and 15 minutes (75 minutes) of vigorous-intensity aerobic actvity (i.e., jogging or running) every week and muscle -strengthening activities on 2 or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders, and arms). An equivalent mix of moderate- and vigorous-intensity aerobic activity and muscle -strengthening activities on 2 or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders, and arms).
Live healthy, live longer Making just a few changes in your lifestyle can help you live longer. A recent study found that four bad behaviors—smoking, drinking too much alcohol, not exercising, and not eating enough fruits and veggies—can hustle you into an early grave, and, in effect, age you by as many as 12 years. Fortunately, you can do something to correct these and other unhealthy behaviors. Adopt the following nine habits to keep your body looking and feeling young. Take the first step. Start with walking! Why? It's easy and it works!
We've got the tools and resources to get you on the right path to a healthier lifestyle. It's Easy
And walking isn't your only option. Try these tips for increasing physical activity wherever you are. You may be surprised at all your opportunities to increase your physical activity every day. Consider carrying this list with you for one day. Check off the ways you notice that you could increase your physical activity.
