On a model of human bioenergetics.

A three component hydraulic model has been proposed to represent the energy flows during human exercise and recovery. This model was accompanied by a sketch indicative of the graphical solution but had not been solved mathematically. This paper describes the model and demonstrates the method of mathematical solution, illustrated with a numerical example. Plotted graphically, this particular solution differs from both the "sketch solution" and from what actually happens under experimental conditions. These points of discrepancy are discussed with a view to their rectification and the development of a refined model.
