Probability distribution of orientations of cross-bridge lever arms during contraction (red) and relaxation (blue) of myofibrils. All the probability distributions could be fit by a single Gaussian y = a exp[−0.5(x−xo/b)2] (solid line). The goodness of fit was assessed by χ 2 in the Origin program. The FWHMs of contracting and relaxed myofibrils were 0.247 and 0.358, respectively
