Various sports activities involve specific demands for energy. For example, sprinting and jumping are high-energy output activities, requiring a relatively large production of energy for a short time. Long-distance running and swimming, on the other hand, are mostly low-energy production for a prolonged time. Other physical activities demand a blend of both high- and low-energy. These various energy demands can be met by the different processes by which energy can be supplied to the skeletal muscles.
