Explanation:
Detailed explanation-1: -During prolonged continuous exercise energy consumption will be rather stable, and skeletal muscle glycogen content will be reduced by 50–70% after 60 min cycling at 75% of VO2max (Hermansen et al., 1967; Saltin and Karlsson, 1971).
Detailed explanation-2: -To give you a rule of thumb: after approximately 80 minutes of exercise at a maximum lactate steady state, glycogen stores are depleted.
Detailed explanation-3: -As you exercise, your body breaks down glycogen into glucose for energy. Once glycogen stores are depleted, your body runs out of fuel and you will begin to feel tired. Consuming carbohydrates while you exercise will prevent glycogen depletion.
