During SPOC each sarcomere repeated the AGI-5198 of slow shortening and rapid lengthening phases in a sawtooth waveform (Fig. 1B). The period of oscillation was 1.1 ± 0.3 s, while the peak-to-peak amplitude was 165 ± 71 nm per sarcomere (means ± SD; n = 10 from 10 myofibrils upon the first activation of each myofibril at pCa 6.1). In addition, the lengthening phase transmitted to the adjacent sarcomeres along the myofibril over 10 sarcomeres with the transmission time of epistasis small fluctuation of SL was observed in the phase-contrast image at pCa 6.3, but the amplitude of the fluctuation was statistically insignificant compared with the RMS noise level in steady contraction. These data were classified as contraction in the following analysis.
