Strength Training Helps to Prevent Diabetes

One third of Americans will become diabetic because they eat too much and exercise too little. A study in Medicine and Science in Sports and Exercise (July 2006) shows that lifting weights can help to prevent and to treat diabetes.

Extra fat prevents your body from responding normally to insulin. Before insulin can do its job of driving sugar from the bloodstream into cells, it must first attach to little hooks on cell membranes called insulin receptors. Having extra fat in cells turns these receptors inward, making it far more difficult for insulin to attach to the receptors. This prevents insulin from doing its job of lowering blood sugar levels, even though your body is making plenty of insulin. That's why anything that makes you fat increases your risk for diabetes. Doctors can measure how cells respond to insulin with a sugar tolerance test.

In this study, adolescent boys were given a program of lifting heavy weights twice a week. After only 16 weeks, their muscles were larger and they lost fat. Sugar tolerance tests showed that the ability of their bodies to clear a load of sugar from their blood streams improved dramatically. This means that a regular weight lifting program deceases insulin resistence and thus reduces risk for becoming diabetic.

What is diabetes?

A disease in which the body cannot convert food into energy because of a lack of insulin (a hormone produced by the pancreas), or because of an inability to use insulin. Diabetes is a serious condition that can cause complications ranging from numbness to loss of vision to coma. It also significantly raises the risk for other problems, such as stroke and heart disease. About 17 million Americans have diabetes.
A hereditary or developmental problem with sugar metabolism. Caused by a failure of the pancreas to produce enough insulin. Juvenile diabetes, or type 1 diabetes, is treated with diet, exercise and insulin. Type 2, formerly called adult onset, is now seen in overweight children. It is treated with diet, exercise and medication. In severe cases, type 2 diabetes is also treated with insulin.
A chronic condition associated with abnormally high levels of glucose (sugar) in the blood. The two types of diabetes are referred to as insulin-dependent (type I) and non-insulin dependent (type II). Type I diabetes results from a lack of adequate insulin secretion by the pancreas. Type II diabetes (also known as adult-onset diabetes) is characterized by an insensitivity of the tissues of the body to insulin secreted by the pancreas (insulin resistance).
