Risks factors for cardiovascular disease that can and can not be changed.The risks factor for cardiovascular disease have been categorize by the American Heart Association (AHA) as the following: (1) Major risks factors that can not be changed (increasing age, male gender, and heredity). (2) Major risk factors that can be changed (cigarette/tobacco smoke, high blood cholesterol, high blood pressure, and physical inactivity).(3) Other factors diabetes, Obesity, and stress.Physiological Benefits of physical Activity Research shows that moderate, not necessarily extensive exercise is sufficient for good health. For example, for both women and men, the chance of dying from cancer and several other diseases is greater for individuals with sedentary life-styles than those who engage in a daily brisk walk of 30 to 60 minutes (Cufman, 1993). Moderate regular exercise, lasting say 15 to 30 minutes, five times a week also has been found to improve health. In fact, high levels of exercise increase the risk of injuries (Edlin p.130 ).If you exercise regularly, your overall risk of a heart attack is about 50 percent less than if you are inactive and out of shape. With routine exercise you can reach a level of physical fitness comparable to an active person ten to twenty years younger. Regular exercise may also lower your cholesterol and blood pressure, and reduce the risk of diabetes.Exercise increases the size of coronary arteries and reduce clogging due to atherosclerosis. Exercise also increases the efficiency of your blood's oxygen-carrying capacity and your muscles' uptake of oxygen.Exercise has been linked to increased levels of high density lipoprotein (good) cholesterol and decreases low-density lipoprotein (bad) cholesterol and triglyceride levels. After exercising for 6 to 12 months, lowered cholesterol levels can mean as much as a 30 percent reduction in the risk of coronary artery disease (Edlin p.130).Psychological Benefits of physical Activity Regular physical activity can result in periods of relaxed concentration, characterized by reduced physical and psychic tension, regular breathing rhythms, and increased self-awareness. This effect is often compared to meditation and is the aim of all eastern body workouts, including Hatha yoga, t'aichi ch'uan, and many martial arts.Moderate exercise for middle-aged and older adults is emerging as an important aide to the treatment of many diseases. These include diabetes, osteoporosis, osteoarthritis, insomnia, deconditioning, and (to a degree) obesity. A recent report from the United States Surgeon General recommends that most adults exercise most if not all days of the week, accumulating 180 minutes of moderate intensity exercise weekly. If a person have been previously sedentary, encourage them to start a slow, stepwise exercise program. Ongoing support, encouragement, and follow-up can help them commit to and maintain a program of regular exercise.Exercise has long been recognized as a key component...
