[Maximum rigor tension developed in a single rabbit glycerinated skeletal muscle fiber]

Rigor tension was found to vary significantly with the replacement rate of the relaxing with the rigor solutions. The maximum value of rigor tension (Prig = 130 kN/m2) was obtained under slow (5 microL/sec) replacement of the solutions. The difference in the tensions may reflect variations in the amount of "compliance" taken out from the fibre.
