At matched loads, aging does not alter ankle, muscle, or tendon stiffness

K. Jakubowski, D. Ludvig, S. S. Lee, E. J. Perreault

This study finds that aging does not change muscle or tendon stiffness at matched loads but reduces stiffness at matched effort due to decreased strength.

The nervous system leverages the non-linear properties of the Achilles tendon to regulate ankle impedance during postural control

K. Jakubowski, D. Ludvig, E. J. Perreault, S. Lee

The paper quantifies the contributions of triceps surae and Achilles tendon to ankle impedance during postural control and finds that tendon stiffness dominates above low loads.

Simultaneous quantification of ankle, muscle, and tendon impedance in humans

K. L. Jakubowski, D. Ludvig, D. Bujnowski, S. Lee, E. J. Perreault

This study develops a technique to simultaneously quantify ankle, muscle, and tendon impedance in humans and validates its reliability.

Frontal plane ankle stiffness increases with axial load independent of muscle activity

Z. Villamar, E. J. Perreault, D. Ludvig

This study shows that frontal-plane ankle stiffness increases threefold with axial load, independent of muscle activity.

Multidirectional measures of shear modulus in skeletal muscle

W. E. Reyna, E. J. Perreault, D. Ludvig

This study measures shear modulus in three orientations of skeletal muscle in rats, finding orientation-dependent values but no significant effect of muscle architecture.

Relationship between shear wave velocity and muscle activation is inconsistent across different muscle types

M. Bernabei, D. Ludvig, T. G. Sandercock, E. J. Perreault, S. S. M. Lee

This study examines how shear wave velocity relates to muscle activation across different muscle types and finds inconsistent relationships.
