A comparison of the mechanical properties in the longitudinal and transverse directions during cyclical loading. (A) The elastic modulus is significantly greater in the longitudinal direction (P < 0.0001). (B) The aponeurosis behaves as an efficient spring in both the longitudinal and transverse directions, with slightly greater resilience in the longitudinal direction (P = 0.005). Error bars are the standard deviations of the mean.
