Brief, rigorous exercise cuts diabetes risk

"Rigorous exercise of short duration can significantly affect the body's ability to process sugars and fight diabetes, a new study suggests. In research published in the journal BMC Endocrine Disorders, scientists from Heriot-Watt University in Edinburgh, Scotland, say they found that brief but intense exercise every day or two may help reduce the risk of diabetes. James Timmons, a professor in the school of engineering and physical sciences, says he and a team of investigators looked into the effect of "high-intensity training" on the insulin action and blood sugar control in 16 young, healthy male volunteers. They found that insulin sensitivity improved significantly in the two-week study. Regular exercise can help reduce the risk of type 2 diabetes and heart disease" - WebMD
