Optimising the flow of mechanical energy in musculoskeletal systems through gearing

This paper analyzes how mechanical advantage affects energy flow in musculoskeletal systems and identifies optimal gearing for efficient energy delivery.

The Murphy number: how pitch moment of inertia dictates quadrupedal walking and running energetics

The paper introduces the Murphy number, showing it dictates quadrupedal gait energetics by affecting walking and running strategies through rotational dynamics.

A simple model of a quadruped discovers single-foot walking and trotting as energy optimal strategies

A quadruped model identifies walking and trotting as energy-optimal gaits through trajectory optimization, matching observed animal movement patterns.

Reducing gravity takes the bounce out of running

The paper shows that humans reduce vertical leap height in reduced gravity by adjusting takeoff velocity to balance energetic costs of stance and leg-swing work.
