Energy is required for all kinds of bodily processes including growth and development, repair, the transport of various substances between cells and of course, muscle contraction. It is this last area that Exercise Scientists are most interested in when they talk about energy systems.
Whether it’s during a 26-mile marathon run or one explosive movement like a tennis serve, skeletal muscle is powered by one and only one compound… adenosine triphosphate (ATP) (2). However, the body stores only a small quantity of this ‘energy currency’ within the cells and its enough to power just a few seconds of all-out exercise (5). So the body must replace or resynthesize ATP on an ongoing basis. Understanding how it does this is the key to understanding energy systems.
Understanding energy systems underpins the study of exercise and the effect it has on the human body.
Bioenergetics… or the study of energy flow through living systems is usually one of the first chapters in any good exercise physiology text. But the current model of human energy systems is being challenged…
Recent research and practical experience expose its limitations, in particular with regard to fatigue.
This article outlines the three basic energy pathways, their interactions with one another and their relevance to different sporting activities. It finishes with a brief look at some of the more recent research and subsequent new models of human energy dynamics that have been proposed as a result.
