ResumoIn Brief The power needs of muscle are supplied by rapid anaerobic glycogenolytic ATP generation. Lactate is built up by the mismatch between steady state energy needs and short-term power demands and the increased concentration drives the lactate shuttle. In this model, contributions to fatigue should be looked for in the flux of glucose through glycogen rather than in the concentrations of fuel. The turnover of glycogen in muscle generates lactate and provides ATP rapidly to satisfy the power needs of contraction.
