Human power in maximum exercise lasting for a few seconds is dependent on high energy phosphates (ATP + PCr) present in the muscle fibres. In a whole series of research papers Professor Anthony J Sargeant has investigated how the rate of utilization varies between different muscle fibre types. In this research carried out by Christina Karatzaferi, his talented Greek PhD student, they report for the first time the rate of recovery of high energy phosphate levels following exercise in different human muscle fibre types.
