Whether working or resting, muscles expend metabolic energy. It is the aim of muscle
energetics to understand the manifold energy pathways that run from sources in glycolysis
and oxidative phosphorylation to sinks in the various ATPases that support excitation,
activation and contraction. By understanding energy supply and demand we hope to
clarify how various essential processes in the cell interact to maintain cell function.
Methodologies range from calorimetry to intracellular
