Physical Inactivity Risk Factors

Physical activity is necessary to maintain proper function of the body's systems. Blood circulation, tissue and cell regeneration, digestion and healthy organ function are all dependent on regular physical activity. Without physical activity, the buildup of deposits in the bloodstream occur, causing blockage in the arterial network of the body and consequently in the body's organs, including the brain, heart, lungs, liver and kidneys. This can cause a breakdown in the function of these organs and arteries, often causing serious damage.

  1. Side Effects

    • The function of the heart is critical to sustaining the blood flow necessary to maintain the proper function of the rest of the body's systems. If physical activity is insufficient, a buildup of calcium, cholesterol and fatty substances in the arteries that supply blood to the heart can occur, which can cause the heart to function improperly. This can lead to arteriosclerosis (damage to the arteries), hypertension (high blood pressure), high triglycerides, low levels of HDL cholesterol and diabetes.

    Other Side Effects

    • The lack of proper blood flow will affect every other function of the body as well, including the respiratory system (lungs), the renal system (liver) and the body's overall ability to regenerate cells and tissue, which is critical in maintaining the integrity of muscles and bones. An unhealthy circulatory system can affect the function of the brain as well, often leading to aneurysms, strokes and even coma or paralysis. All of these conditions can also affect the mental health as well as the physical health of individuals who do not engage in regular physical activity.

    Healthy Physical Activity

    • Basic types of physical activity can include everyday activities such as walking, leisurely rides on a bicycle, housework, gardening, golfing, swimming and even dancing. These activities, done on a regular basis, are "low impact" and do not require a great deal of exertion, yet will still maintain sufficient blood flow and organ function. Depending on the health or age of the individual, these activities can be intensified to maximize their effect, such as brisk walking, light jogging and more intense cycling.

    Higher Levels of Physical Activity

    • Increasing the level of physical exertion can also increase the efficiency of a body's functions. For individuals who can safely engage in higher levels of exertion, activities such as aerobic exercises, weightlifting and more intense jogging can be included in a regular fitness routine. Sports activities can also be beneficial in maintaining healthy body functions, such as tennis, handball, skiing, soccer, racquetball, basketball and football.

    Avoiding Risks

    • Adopting a regular program of daily physical activity is recommended by many medical and health care professionals and organizations, including the American Diabetes Association, the American Medical Association and the World Heart Federation. The level of recommended physical activity depends on many factors, including the age and overall condition of the individual, as well as the consideration of any other medical conditions present.
