Fig. 5. A schematic representation of the qualitative changes that, on theoretical
grounds, might be expected of the efficiency/velocity relationship consequent
upon an increase in muscle temperature. In the illustration, the solid line
shows the efficiency/velocity relationship for a muscle that has an optimum
velocity for maximum efficiency close to 60 revs min-1 under normal
conditions. The dashed line indicates the expected rightward shift consequent
upon an increase in muscle temperature. Thus, increasing muscle temperature at
60 revs min-1 results in a decrease in efficiency from point a to
b. In contrast, at a higher movement frequency (120 revs min-1),
efficiency increases from to c to d as a result of the rightward shift in the
relationship.
