How physical activity impacts health

Tagged:  

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.

Health Benefits of Exercise

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.

13 Scientifically Proven Health Benefits Of Exercise

We've all heard it before, "Exercise is good for you because...."

Nowadays you can't check out at the grocery store or do much of anything without being reminded that us mortal humans need to exercise. Still, we persist, procrastinate and eventually complain that we're overweight, sick, dying, etc.

Listen. Some exercise is better than none, more exercise is generally better than less, and no exercise can be disastrous. No one is asking for you to start a rigorous daily regimen, just do something. If you need motivation, here is a list of scientifically proven health benefits that regular exercise brings.

* Longevity. People who are physically active live longer. According to a 20 year follow-up study, regular exercise reduces the risk of dying prematurely.

* New brain cell development, improved cognition and memory. Exercise stimulates the formation of new brain cells. Researchers found that the areas of the brain that are stimulated through exercise are responsible for memory and learning. For instance, older adults who engage in regular physical activity have better performances in tests implying decision-making process, memory and problem solving.

* Improved sexual function and better sex life. Regular exercise maintains or improves sex life. Physical improvements in muscle strength and tone, endurance, body composition and cardiovascular function can all enhance sexual functioning in both men and women. Researchers revealed that men who exercise regularly are less likely to have erectile dysfunction and impotence than are men who don't exercise.

* Exercise is a powerful antidepressant. Study after study has shown that exercise promotes mental health and reduces symptoms of depression. The antidepressant effect of regular physical exercise is comparable to the potent antidepressants like Zoloft. It may take at least 30 minutes of exercise a day for at least three to five days a week to significantly improve symptoms of depression.

* Cardiovascular health. Lack of physical activity is one of the major risk factors for cardiovascular diseases. Regular exercising makes your heart, like any other muscle, stronger. A stronger heart can pump more blood with less effort.

* Cholesterol lowering effect. Exercise itself does not burn off cholesterol like it does with fat, however, exercise favorably influences blood cholesterol levels by decreasing LDL (bad) cholesterol, triglycerides and total cholesterol and increasing HDL (good) cholesterol.

* Prevention and control of diabetes. There is strong evidence from high quality studies (e.g. Finnish Diabetes Prevention Study) that moderate physical activity combined with weight loss and balanced diet can confer a 50-60% reduction in risk of developing diabetes.

* Blood pressure lowering. The way in which exercise can cause a reduction in blood pressure is unclear, but all forms of exercise seem to be effective in reducing blood pressure. Aerobic exercise appears to have a slightly greater effect on blood pressure in hypertensive individuals than in individuals without hypertension.

* Reduced risk of stroke. Research data indicates that moderate and high levels of physical activity may reduce the risk of total, ischemic, and hemorrhagic strokes.

* Weight control. Regular exercise helps to reach and maintain a healthy weight. If you take in more calories than needed in a day, exercise offsets a caloric overload and controls body weight. It speeds the rate of energy use, resulting in increased metabolism. When metabolism increases through exercise, you will maintain the faster rate for longer periods of a day.

* Muscle strength. Health studies repeatedly show that strength training increases muscle strength and mass and decreases fat tissue.

* Bone strength. An active lifestyle benefits bone density. Regular weight-bearing exercise promotes bone formation, delays bone loss and may protect against osteoporosis - form of bone loss associated with aging.

* Better night sleep. If you suffer from poor sleep, daily exercise can make the difference. The natural dip in body temperature five to six hours after exercise may help to fall asleep.
