Total volume change and normalized stress on the +<i>x</i> face of the muscle after passive lengthening to a stress of 1 × 10⁵ Pa and fixed length contraction to an activation of 100%.

The stress was normalized to σ0. These values are measured with homogenization parameters of α = 0.05 and sECM = 250.应力已归一化至σ₀。本次测量采用的均质化参数为α=0.05与sECM=250。
