WebMuscle glycogen and blood glucose contribute equally to carbohydrate energy production over 2-3 h of moderate-intensity exercise; fatigue develops when these substrates are depleted. Active people can deplete muscle glycogen with 30-60 min of high intensity, intermittent exercise. Web-Main function=maintain ATP levels early in exercise -Energy yield= 1 mol ATP per 1 mol PCr 2. Glycolytic System (glycolysis) -Anaerobic -Glucose/glycogen broken down to pyruvic acid. Pyruvic acid converted to lactic acid when no O2. -Energy yield= 1 mol glucose yields 2 mol ATP; 1 mol glycogen yields 3 ATP 3.
