1. The effect of muscle length on the myoplasmic free Ca2+ concentration ([Ca2+]i) and tetanic force production of intact single muscle fibres was investigated in the mouse flexor brevis muscle. Muscle fibres were analysed at 100 microns intervals from 100 microns shorter than the optimum length (L(zero)) to 300 microns longer than L(zero). The fluorescent Ca2+ indicator indo-1 was used to measure [Ca2+]i. 2. Changes in muscle length did not significantly affect tetanic or resting [Ca2+]i… CONTINUE READING
