The fiber was subjected to repeated releases. Values of Trec (filled circles) and the tension immediately before release To (open circles) are plotted against time in high-Ca rigor solution. Tension changes in the fiber in response to the first to the ninth release-restretch cycles are shown in the inset. Note that Trec decreases by ~65% for the first 10min in rigor solution, and then remains almost unchanged over many minutes until it eventually disappears, while To decreases continuously with time in rigor solution.
