Implication

Directional stiffness changes in frog muscle challenge isotropic contraction models; leaves open cross-bridge validation in mammalian systems.

Population

Frog skeletal muscle

Intervention

Measurement of propagation velocity of ultrasonic waves (3-7 MHz)

Outcome

Longitudinal and transverse muscle stiffness changes during isometric contraction and rigor statesurrogate

Ultrasonic wave measurement reveals that longitudinal stiffness increases and transverse stiffness decreases during isometric contraction in frog skeletal muscle, reflecting cross-link formation.
