Learn how to use physical activity to prevent and alleviate the effects of diabetes.What is the role of physical activity in treating diabetes? In discussing this topic, it's important to recognize that physical activity has been used to treat diabetes for 1000 of years. Moreover, even after insulin was isolated in 1922, exercise was considered along with diet and insulin as an important part of the treatment regimen for diabetes. Before we delve into exactly how physical activity can impact the management of diabetes, I want to look first at the overall relationship between physical activity and the risk of developing diabetes. Data from a number of studies have provide a convincing evidence for the role that regular exercise can play in reducing the risk of Type 2 diabetes. In one study, the risk of Type 2 diabetes increased as physical activity levels declined and time spend watching TV increased. In another study, it was demonstrated that person with low levels of leisure time physical activity were at the highest risk of developing Type 2 diabetes. While the lowest risk of Type 2 diabetes was observed in the most active group. Those individuals who displayed moderate levels of physical activity demonstrated marked reductions in disease risk compare to the least active group. This finding is consistent with what we have talked about in earlier programs that is that numerous health benefits can be gained by performing moderate physical activity on a regular basis. Exactly how does physical activity aid in transporting blood sugar into your muscles. When physical activity is performed your muscles contract and when they do, an insulin like effect is created. What that means is that when you are physical active glucose intake into your muscles increases by 7 to 20 fold compared to resting conditions. Within in the cell, muscle activity singles what are known as glucose transporters to migrate to the cell membrane and usher glucose in. Since muscle activity produces in insulin like effect, less insulin is require to move glucose into your muscles conversely during and following exercise skeletal muscle display an increase sensitivity to the available insulin. What this means is that for any given level of insulin? More blood glucose can be moved into the muscle and this effect can last anywhere from several hours to a few days. With training insulin sensitivity is elevated due to an increase in the total content of glucose transporters and the stronger insulin effect at the cell level. This increase in insulin sensitivity is what makes physical activity so useful in treating persons with diabetes, since it reduces the need for insulin while helping to lower blood glucose levels to more normal values. Regular exercise and physical activity can improve the health and quality of life of both Type 1 and Type 2 diabetics. Regular aerobic and resistance training combine with dietary therapy can result in better aerobic function, favorable changes in cholesterol profiles, decreases in weight, and blood pressure, and greater lean body mass. In addition, daily physical activity can help to improve the psychological state of the diabetic by raising self esteem and lowering depression and anxiety. Regular physical activity can decrease the insulin requirements of well controlled Type 1 diabetics by 30 to 50 percent. With each bout of exercise, the improvement in insulin sensitivity can last for 1 or 2 days before returning to pre-exercise values. This finding highlights the importance of being active on a daily basis, so that you can take full advantage of the enhancement in insulin sensitivity that comes from engaging in single bouts of physical activity and exercise. Before starting an exercise program, the diabetic should undergo a comprehensive medical screening, since strenuous exercise can aggravate eye, kidney or nerve problems that may already exist.
