Carbohydrates are the fuel source when we increase the intensity to 1.0 respiratory rate at over 80% HRM, They are in the form of glucose that has either been freed up from the glycogen stores or as a glucose polymer. It is possible to burn up to 150g glucose during an intense exercise session. Glycogen stores are limited and depend largely on: A, an athletes nutritional status. B, intensity and training level. Endogenous glycogen stores during moderate to high intensity levels (65 – 85% VO2max) of exercise may only last from 90 min to 3 h. Studies show decrements in muscle glycogen were offset by 49% when CHO was provided before and during resistance exercise. Ask us for help selecting the BEST carb source for your training needs.
