What is the body's primary fuel for endurance exercise? I know that muscle glycogen is used for short, intense bouts of muscular movement, but what about endurance. Does your body utilize fatty acids as a primary fuel or liver glycogen?

the lower intensity, the more fatty acid utilization, the higher intensity, the more carbohydrate metabolism. there are charts on google if you search but thats the jist of it

x2 ^^^ you do use more Intramuscular Triglyceride stores of fat during endurance exercise, up to about 60% of your VO2 max. Hence why runners need a little bit of fat to keep them going during ultramarathons etc.Originally Posted by AllGenetix
