FIGURE 3.

Lack of an effect of phosphate on catch force. Typical force traces showing the effect of 8 mM phosphate on force in pCa 6 and the absence of an effect of 8 mM phosphate on force output when the muscle is in catch at pCa > 8. The dotted line shows a muscle to which phosphate was added during catch, whereas the solid line shows the response of a muscle to which no phosphate was added during catch.
