Exercise Reduces Diabetes by Reducing Insulin Resistance
It has been shown numerous times that exercise may prevent certain diseases such as heart disease and diabetes, although the exact mechanism of this effect is often disputed. This study found that one of these mechanisms is that physical activity causes a reduction in insulin resistance.
- The study included 5159 men aged 40 to 59 years with no history of coronary heart disease, type 2 diabetes, or stroke.
- During an average follow-up period of 16.8 years, there were 616 cases of major coronary heart disease events (fatal and nonfatal) and 196 incident cases of type 2 diabetes.
- Physical activity was inversely related to coronary heart disease rates, with the lowest rates in the men undertaking moderate physical activity and with no further benefit thereafter.
- For type 2 diabetes, risk decreased progressively with increasing levels of physical activity.
- Physical activity was associated with serum insulin level and with factors associated with insulin, ie, heart rate, hyperuricemia (elevated uric acid in the urine), diastolic blood pressure, and high-density lipoprotein cholesterol level, and with -glutamyltransferase level, a possible marker of insulin resistance in the liver.
To maintain that insulin resistance definitely plays an important role in the development of diabetes, although they were not able to come to the same conclusion in regards to heart disease. They feel that the majority of the risk reduction for heart disease induced by exercise must be obtained through a different mechanism.Insulin is the key to the vast majority of chronic illness. Fortunately, it is the variable most easily influenced by healthy eating and exercise. Conventional medicine will prescribe drugs to lower blood sugar in type 2 diabetics and give verbal acknowledgment to exercise. However, few really encourage it as aggressively as they should. It is an incredibly powerful tool. Without this appreciative tool you would be a type 2 diabetic. Running/walking 20 miles a week seems to keep the blood sugar in a nearly ideal range.One does not have to run 20 miles per week, but most diabetics will benefit from one hour of intense exercise at least five times per week, and more if their blood sugar is currently out of control.
