Postural adaptations may contribute to the unique locomotor energetics seen in hopping kangaroos

L. H. Thornton, T. Dick, J. R. Hutchinson, G. A. Lichtwark, C. P. McGowan, J. Rubenson, A. Wiktorowicz-Conroy, C. Clemente

This study uses a 3D musculoskeletal model to analyze how hindlimb posture affects tendon stress and energy storage in hopping kangaroos, revealing posture-mediated elastic energy savings.

Increased force and elastic energy storage are not the mechanisms that improve jump performance with accentuated eccentric loading during a constrained vertical jump

E. Y.-S. Su, T. J. Carroll, D. Farris, G. A. Lichtwark

This study investigates whether accentuated eccentric loading improves jump performance by increasing ground reaction force and elastic energy storage, finding no significant increase in force or jump height.

An in-silico investigation of the effect of changing cycling crank power and cadence on muscle energetics and active muscle volume

C. D. Riveros-Matthey, T. J. Carroll, M. J. Connick, G. A. Lichtwark

This study uses musculoskeletal modeling to investigate how cycling power and cadence affect muscle energetics and active volume, finding that minimizing active muscle volume aligns with self-selected cadence.

Linking Muscle Mechanics to the Metabolic Cost of Human Hopping

L. N. Jessup, L. A. Kelly, A. G. Cresswell, G. A. Lichtwark

This study measures activation and work requirements of lower-limb muscles and metabolic energy during human hopping under varied conditions, showing increased metabolic power with lower frequency and higher height.

The effects of crank power and cadence on muscle fascicle shortening velocities, muscle activations and joint-powers during cycling.

C. D. Riveros-Matthey, T. J. Carroll, G. A. Lichtwark, M. J. Connick

This study examines how cadence and power affect muscle fascicle shortening velocities, muscle activation, and joint powers during cycling, finding that preferred cadence is not primarily driven by optimizing fascicle velocities.

Modulations in motor unit discharge are related to changes in fascicle length during isometric contractions

E. Martinez-Valdes, F. Negro, A. Botter, P. A. Pincheira, G. L. Cerone, D. Falla, G. A. Lichtwark, A. G. Cresswell

This study shows that changes in tibialis anterior fascicle length are closely related to motor unit firing rate and dorsiflexion torque during isometric contractions.

Biceps femoris long head sarcomere and fascicle length adaptations after three weeks of eccentric exercise training

P. A. Pincheira, M. A. Boswell, M. V. Franchi, S. L. Delp, G. A. Lichtwark

This study investigates if three weeks of eccentric exercise increases Biceps femoris long head fascicle length through sarcomere addition, finding instead that sarcomere length increases without changes in sarcomere number.
