Abstract
The bulk of research on exercise metabolism has been concentrated on activity durations of less than one hour. These studies strongly indicate that, for exercise of short duration, the energy requirement can easily be met by glycogen and fatty acid breakdown. Recent work has indicated a small, but important, role of amino-acid metabolism during this type of exercise [6, 7, 12, 22, 23, 29], and suggests that this role may become increasingly important as work duration increases [17, 23, 27].
