Contractile work and biarticular mechanisms of the triceps surae muscles facilitate net ankle mechanical work at high walking speeds

The paper examines how triceps surae muscles and biarticular gastrocnemii contribute to net ankle mechanical work at different walking speeds.

Quantifying mechanical loading and elastic strain energy of the human Achilles tendon during walking and running

This study measures Achilles tendon strain, force, and strain energy during walking and running using an in vivo method, finding speed affects strain but not enough for adaptation, and identifying recoil energy during running.
