During the first 30 minutes of heavy exercise, most energy is derived from glycogen stored in muscles and liver, as well as plasma glucose. This is because the body quickly needs to generate ATP for muscle contractions, and glycogenolysis provides a rapid source of glucose for ATP production. The percentage of energy obtained from plasma free fatty acids does not exceed that of mild exercise during this initial phase, and the reliance on plasma glucose is typically higher than in moderate exercise due to the intensity of the activity.
