Exercise can prevent the following diseases:
• Osteoporosis
• Heart Disease
• Stroke
• Type II diabetes
• Obesity
• Back Pain

According to a wealth of research, exercise is the silver bullet for a better quality of life.

Ward Off Disease
Research has confirmed that any amount of exercise, at any age, is beneficial. And, in general, the more you do, the greater the benefits. The National Academy of Sciences has recommended that everyone strive for a total of an hour per day of physical activity. Sounds like a lot, but the hour can be made up of several shorter bursts of activity (it can be walking, gardening, even heavy housecleaning) done throughout the day.

Physical activity is an essential part of any weight-loss program, to maximize your fat loss while keeping valuable muscle mass. But exercise has many other health and longevity benefits. It can help prevent or improve these conditions:

1. Heart Disease. Regular activity strengthens your heart muscle; lowers blood pressure; increases "good" cholesterol (high-density lipoproteins or HDLs) and lowers "bad" cholesterol (low-density lipoproteins or LDLs); enhances blood flow; and helps your heart function more efficiently. All of these benefits reduce the risk of stroke, heart disease, and high blood pressure.
Researchers at Duke University suggest that the amount of physical activity, rather than its intensity, has the biggest impact on improving blood lipids (cholesterol). According to The New England Journal of Medicine, these researchers also found that any exercise is better than none -- although more is better.

2. Stroke. In an analysis of 23 studies, researchers found that being active reduces your risk of having and dying from a stroke. According to a study published in the journal Stroke, moderately active study participants had 20% less risk of stroke than less active participants.

3. Type II Diabetes. This disease is increasing at alarming rates -- by 62% since 1990 -- and 17 million Americans now have it. Physical activity can enhance weight loss and help prevent and/or control this condition. Losing weight can increase insulin sensitivity, improve blood sugar and cholesterol levels, and reduce blood pressure -- all of which are very important to the health of people with diabetes.
In a study published in the Annals of Internal Medicine, Frank Hu, MD, of the Harvard School of Public Health found that a brisk walk for one hour daily could reduce the risk of type II diabetes by 34%

4. Obesity. Overweight and obese conditions can be prevented or treated with exercise along with a healthy diet. Activity helps to reduce body fat and increase muscle mass, thus improving your body's ability to burn calories. The combination of reduced calories and daily exercise is the ticket to weight loss. And controlling obesity is critical, as it is a major risk factor for many diseases. Lowering your body mass index (BMI) is a sure way to reduce your risk of dying early and to live a healthier life.

5. Back Pain. Back pain can be managed or prevented with a fitness program that includes muscle strengthening and flexibility. Having good posture and a strong abdomen is the body's best defense against back pain.

6. Osteoporosis. Weight-bearing exercise (such as walking, jogging, stair climbing, dancing, or lifting weights) strengthens bone formation and helps prevent the osteoporosis or bone loss often seen in women after menopause. Combine a diet rich in calcium and vitamin D with regular weight-bearing exercise for maximum results.
According to The Journal of the American Medical Association, data from the Nurses' Health Study showed that women who walked four or more hours per week had 41% fewer hip fractures than those who walked less than an hour a week.

7. Psychological Benefits. Improved self-esteem is one of the top benefits of regular physical activity. While exercising, your body releases chemicals called endorphins that can improve your mood and the way you feel about yourself. The feeling that follows a run or workout is often described as "euphoric" and is accompanied by an energizing outlook. Exercise can help you cope with stress and ward off depression and anxiety.
And these are just a few of the ways exercise improves your health. Studies have suggested it can also help with certain types of cancer, improve immune function, and more
“Regular physical activity that is performed on most days of the week reduces the risk of developing or dying from some of the leading causes of illness and death in the United States.
• Reduces the risk of dying prematurely.
• Reduces the risk of dying prematurely from heart disease.
• Reduces the risk of developing diabetes.
• Reduces the risk of developing high blood pressure.
• Helps reduce blood pressure in people who already have high blood pressure.
• Reduces the risk of developing colon cancer.
• Reduces feelings of depression and anxiety.
• Helps control weight.
• Helps build and maintain healthy bones, muscles, and joints.
• Helps older adults become stronger and better able to move about without falling.
• Promotes psychological well-being.”


Health Benefits of Exercise

Regular exercise can help protect you from heart disease and stroke, high blood pressure, noninsulin-dependent diabetes, obesity, back pain, osteoporosis, and can improve your mood and help you to better manage stress.
For the greatest overall health benefits, experts recommend that you do 20 to 30 minutes of aerobic activity three or more times a week and some type of muscle strengthening activity and stretching at least twice a week. However, if you are unable to do this level of activity, you can gain substantial health benefits by accumulating 30 minutes or more of moderate-intensity physical activity a day, at least five times a week.

If you have been inactive for a while, you may want to start with less strenuous activities such as walking or swimming at a comfortable pace. Beginning at a slow pace will allow you to become physically fit without straining your body. Once you are in better shape, you can gradually do more strenuous activity.

How Physical Activity Impacts Health

Regular physical activity that is performed on most days of the week reduces the risk of developing or dying from some of the leading causes of illness and death in the United States.

• Reduces the risk of dying prematurely.
• Reduces the risk of dying prematurely from heart disease.
• Reduces the risk of developing diabetes.
• Reduces the risk of developing high blood pressure.
• Helps reduce blood pressure in people who already have high blood pressure.
• Reduces the risk of developing colon cancer.
• Reduces feelings of depression and anxiety.
• Helps control weight.
• Helps build and maintain healthy bones, muscles, and joints.
• Helps older adults become stronger and better able to move about without falling.
• Promotes psychological well-being.

Specific Health Benefits of Exercise

Heart Disease and Stroke. Daily physical activity can help prevent heart disease and stroke by strengthening your heart muscle, lowering your blood pressure, raising your high-density lipoprotein (HDL) levels (good cholesterol) and lowering low-density lipoprotein (LDL) levels (bad cholesterol), improving blood flow, and increasing your heart's working capacity.

High Blood Pressure. Regular physical activity can reduce blood pressure in those with high blood pressure levels. Physical activity also reduces body fatness, which is associated with high blood pressure.

Noninsulin-Dependent Diabetes. By reducing body fatness, physical activity can help to prevent and control this type of diabetes.

Obesity. Physical activity helps to reduce body fat by building or preserving muscle mass and improving the body's ability to use calories. When physical activity is combined with proper nutrition, it can help control weight and prevent obesity, a major risk factor for many diseases.

Back Pain. By increasing muscle strength and endurance and improving flexibility and posture, regular exercise helps to prevent back pain.

Osteoporosis. Regular weight-bearing exercise promotes bone formation and may prevent many forms of bone loss associated with aging.

Psychological Effects. Regular physical activity can improve your mood and the way you feel about yourself. Researchers also have found that exercise is likely to reduce depression and anxiety and help you to better manage stress.

Millions of Americans suffer from illnesses that can be prevented or improved through regular physical activity.
• 13.5 million people have coronary heart disease.
• 1.5 million people suffer from a heart attack in a given year.
• 8 million people have adult-onset (non-insulin-dependent) diabetes.
• 95,000 people are newly diagnosed with colon cancer each year.
• 250,000 people suffer from a hip fractures each year.
• 50 million people have high blood pressure.
• Over 60 million people (a third of the population) are overweight.”
