  • Preload, which determines the initial muscle length, has proved to be a basic determinant of the muscle relaxation phase. The mechanical properties of the papillary muscle of Wistar rats (n = 20) were studied at different initial lengths (L): Lmax and 98 p. 100, 94 p. 100, 90 p. 100, 86 p. 100 and 82 p. 100 Lmax. In isometry, the relaxation phase was proportionally less sensitive to a reduction o…
