Fig. 7From: Energetics of muscle contraction: further trialsInorganic phosphate released (ΔPi), and the difference between ΔPi and −ΔPCr, plotted against the duration of contraction. Vertical bars represent ±1 S.D. The inset shows the difference between ΔPi and −ΔPCr (ΔPi + ΔPCr) in an enlarged scale. Kawano et al. [26]Back to article page
