The effects of physical inactivity

A human exchanges about 10% of oxygen with each normal breath, meaning that about 90% of the oxygen is not used until we breathe deep or exercise. A lack of oxygen in the brain results in disorientation, confusion, fatigue, sluggish concentration and memory problems.

Coronary artery disease

There is no doubt that physical inactivity represents a major risk factor for developing coronary artery disease. Coronary artery disease is a serious condition characterized by deposits of fat, cholesterol, calcium and other substances in the inner lining of arteries that supply blood to the heart muscle. It eventually leads to a heart attack.

Other conditions

It also contributes to other risk factors, including obesity, high blood pressure, high triglycerides, a low level of HDL cholesterol and diabetes.

Types of physical activity

Aerobic activity

It involves repeated use of large muscle groups. Aerobic activities include walking, jogging, cycling or using a wheelchair. These activities raise a man’s endurance and improve the function of the heart and lungs. Aerobic exercise reduces the risk of developing many diseases of the heart and blood vessels.

Strength training

This type of exercise includes the use of weights. It improves strength, bone health and daily function. Strength training should include at least one set of e exercise for each major muscle group.

Stretching exercises

These exercises help improve a person's range of motion. It is proven that they reduce muscle soreness and spasticity and improve movement. Stretching is especially important for persons with mental retardation.

What risk factors are reduced?

Research has proven that regular physical activity helps reduce or eliminate some of the risk factors such as:

• High blood pressure – It is proven that regular aerobic activities can lower blood pressure.
• Cigarette smoking –There is no doubt that smokers who become physically active are more likely to cut down or stop smoking.
• Diabetes – It is a known fact that people with diabetes have big problems in controlling their weight. People at their ideal weight are less likely to develop diabetes. Physical activity may also decrease insulin requirements for people with diabetes.
• Obesity and overweight - Regular physical activity can help people lose excess fat or stay at a reasonable weight which could be a crucial thing for maintaining a healthy life.
• High levels of triglycerides - Physical activity helps reduce triglyceride levels. High triglycerides are linked to developing coronary artery disease in some people.
• Low levels of HDL - Low levels of HDL cholesterol have been linked to a higher risk of coronary artery disease. Recent studies show that regular physical activity can significantly increase HDL cholesterol levels and thus reduce this risk.
• Osteoporosis
• Stroke
• Depression
• Colon cancer
