Taking Sugar During Exercise Increases Power and Endurance
In his July 26, 2009 Fitness and Health E-Zine,  Dr. Gabe Mirkin reported on a  study, which shows that taking  
sugar while you exercise increases the amount of training you can do, with more power and greater time to 
exhaustion.  Having more stored sugar in muscles during a workout helps you exercise longer.  The authors also 
showed that the enzymes used to convert sugar and fat to energy function well when sugar is taken continuously 
during exercise, and muscles trained on sugar had no loss in the amount of stored sugar or the ability to convert 
food to energy.

Another study shows that taking a drink containing both protein and sugar during exercise or competition was 
more effective than a drink containing just sugar.
(Journal of Sport Nutrition and Exercise Metabolism, April 2009);
and another study shows that a protein-sugar drink taken immediately after intense exercise also hastens healing 
of the muscles damaged by hard exercise.

Many studies show that eating before you exercise lowers high blood sugar levels far more effectively than eating 
after you exercise.  During exertion, muscles remove sugar rapidly from the bloodstream, and blood sugar usually 
does not rise too high during exercise and for up to half an hour after you finish exercising.  On the other hand, 
taking refined carbohydrates (sugar or flour) when you are not exercising can cause a high rise in blood sugar 
that increases risk for diabetes and heart attacks, strokes, and nerve damage leading to dementia, blindness and 
deafness, even in people who are not diagnosed as being diabetic.  Exercising after fasting barely lowers high 
blood sugar levels at all.
