Suppose someone was to offer you a magical substance guaranteed to lengthen and improve the quality of your life? This stuff would cut in half your risk of heart disease, make a dramatic improvement in the delivery of oxygen to your body muscles, decrease your mental anxiety and depression, and lower your blood pressure and cholesterol levels. Would you believe that such a potion really existed? If medical evidence supporting these claims could be provided, would you be willing to sacrifice to obtain this health-saving nostrum?
Let us look for the Answer
Such a potion does exist, and although time and effort are involved, it can be obtained quite inexpensively. This "wonder drug" is exercise, particularly aerobic (exercise that increases oxygen intake), such as brisk walking, jogging, swimming, bicycling, and aerobic dance. It should be great suggestion to prepare the
best Bluetooth headphones workout for yourself. And the spectacular benefits are available to all who use it three to five times a week.
However, the use of this "drug" has been associated with many potential side effects, especially when too much is taken. Pain in muscles, joints, and tendons is a real possibility. Use during hot and humid weather is not advised. Large doses during pregnancy may harm the growing fetus. And for those with a high risk for heart disease, use of this substance can imperil life itself.
Research the Information from Experts
You've probably read newspaper reports about exercise author Jim Fixx and the famous basketball player Pete Maravich, both of whom died of heart attacks while they were exercising. Countless other media reports have emphasized the injuries of top athletes, the potential for heat exhaustion and collapse by runners during races, and other ill effects associated with exercise. Many Americans, especially the millions who have joined the exercise movement, have become confused by such reports and are searching for answers.
- Medical science has carefully weighed both the benefits and risks of exercise to provided answers to most of the questions being asked by the public. Before summarizing this evidence, an important underlying principle should be understood: For adults who regularly engage in moderate exercise programs, the benefits far outweigh the risks. However, with increasing amounts and intensity of exercise, the risks expand manyfold (see figure). The bottom line? When you engage in daily moderate aerobic exercise, such as brisk walking, for 30 to 45 minutes, you will realize many more benefits than risks. However, if you undertake an aerobic exercise program that is excessive in amount (usually more than 45 minutes) and intensity (i.e., very hard running or aerobic dance), the potential for experiencing the various risks of exercise escalate sharply.
- Notice that the chart accompanying this article balances the benefits and risks for 12 areas of health and disease. A "surety rating" is given with each benefit or risk; the rating is an estimate of the strength of the medical evidence supporting the various statements. A brief summary of each of the benefits and risks for the 12 areas follows.
Cardiorespiratory system
The cardiorespiratory system comprises the heart, lungs, and blood vessels. The chief duty of these organs is to deliver oxygen to the working muscles during exercise. The evidence from numerous research papers is very firm in support of what is called the "training effect," which refers to the fact that with regular aerobic exercise, the cardiorespiratory system is able to deliver more and more oxygen to the active muscles.
If the information can bring you more passion on doing exercises, it is so great news. For most of people, having healthy life is most important in their life. With healthy lifestyle, they have more time belong to their family members, take part in social activities and do all things they want. Let’s choose your own lifestyle to have better health.
