Speed-specific optimal contractile conditions of the human soleus muscle from slow to maximum running speed

This study examines how the human soleus muscle adjusts its contractile conditions across running speeds, finding optimal efficiency at submaximal speeds and increased power production at higher speeds.

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.

Muscle-specific economy of force generation and efficiency of work production during human running

This study examines the operating conditions of soleus and vastus lateralis muscles during human running, finding that both operate efficiently through optimal force-length and force-length-velocity relationships.

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.
