Mechanical and energetic consequences of rolling foot shape in human walking.

During human walking, the center of pressure under the foot progresses forward smoothly during each step, creating a wheel-like motion between the leg and the ground. This rolling motion might appear to aid walking economy, but the mechanisms that may lead to such a benefit are unclear, as the leg is not literally a wheel. We propose that there is indeed a benefit, but less from rolling than fr...

Mechanical and energetic consequences of reduced ankle plantar-flexion in human walking.

The human ankle produces a large burst of 'push-off' mechanical power late in the stance phase of walking, reduction of which leads to considerably poorer energy economy. It is, however, uncertain whether the energetic penalty results from poorer efficiency when the other leg joints substitute for the ankle's push-off work, or from a higher overall demand for work due to some fundamental featur...

The advantages of a rolling foot in human walking.

The plantigrade human foot rolls over the ground during each walking step, roughly analogous to a wheel. The center of pressure progresses on the ground like a wheel of radius 0.3 L (leg length). We examined the effect of varying foot curvature on the mechanics and energetics of walking. We controlled curvature by attaching rigid arc shapes of various radii to the bottoms of rigid boots restric...

Biomechanical and Energetic Consequences of Walking on Uneven Terrain

Motivation: Although animals and humans navigate complex terrain in their everyday lives, the biomechanical and energetic effects on legged locomotion from uneven terrain have scarcely been quantified [1]. Most gait research has examined locomotion on smooth, level surfaces. Identifying key gait parameters that permit agile locomotion across uneven surfaces could lead to clearer understanding o...

Energetic Consequences of Human Sociality: Walking Speed Choices among Friendly Dyads

Research has shown that individuals have an optimal walking speed-a speed which minimizes energy expenditure for a given distance. Because the optimal walking speed varies with mass and lower limb length, it also varies with sex, with males in any given population tending to have faster optimal walking speeds. This potentially creates an energetic dilemma for mixed-sex walking groups. Here we e...
