1. What are effects of developing a good exercise program?

Exercise may be classified in one of two categories, anaerobic and aerobic, depending on where energy is derived from. There is a distinct difference between the two, and specific training techniques are used to enhance both. Anaerobic exercise does not require oxygen for energy. This is due to the intensity and duration of anaerobic events, which typically are high intensity and last only a few seconds to a minute or two. These activities range from tennis serve to an eight-hundred-meter run.

Aerobic exercise does require oxygen for energy. This is observed during exercise that is less intense but of longer duration. This energy system is primarily used during events lasting longer than several minutes, such as a two-mile run or the Tour de France bicycle race. The potential does exist that one can use both systems, as in soccer, where a match requires ninety minutes of continual activity with short intense bursts of effort.

The American College of Sports Medicine (ACSM), the Centers for Disease Control and Prevention (CDC), and the Surgeon General have all issued statements that recommend placing an emphasis on adopting physical activity into one's lifestyle. Their intention is to make the public more aware of the health benefits associated with increased physical activity, as well as to

There are numerous benefits associated with regular participation in an aerobic exercise program, including improved cardiovascular and respiratory functioning, reduced coronary artery disease (CAD) risk, and increased quality of life. Beneficial improvements in cardiovascular and respiratory function include an increased ability of exercising muscles to consume oxygen, lowered resting and exercise heart rates, increased stamina, resistance to fatigue , more effective management of diabetes , reduced bone-mineral loss, decreased blood pressure , and increased efficiency of the heart. Although it is recognized that specific exercises can be used for the purpose of increasing strength, muscular endurance, and flexibility, it is important to recognize that cardiovascular exercise has the most dramatic effect on the body. This is because cardiovascular exercise engages large muscle groups in an aerobic manner.

Role of Exercise in Disease Prevention

Studies have shown that exercise can have a direct effect on preventing heart disease, cancer , and other causes of premature death. Furthermore, participation in regular physical activity may reduce the rate of occurrence of these maladies. An inverse relationship exists between disease and exercise, ...
