Discusses walking mechanics in humans and animals
A researcher from the Royal Veterinary College (RVC) has contributed to a discussion on the biomechanics of feet for the BBC World Service.
Dr Jim Usherwood, from the RVC's Structure and Motion Laboratory, took part in the BBC World Service programme The Forum, where he explained the biomechanics of the human foot and what part it plays in the way we walk.
He explained that adult humans are more suited to walking than running because out our relatively big flat stiff feet. As we move from one stiff-legged vault to the next, our feet help us to walk more economically, using very little energy.
Dr Usherwood then went on to explain that as we switch from on vault to another, we push from the balls of our feet and crash with the heel of the next foot. During this period, the flat human foot allows forces to travel through the ankle, leaving both shin and calf muscles largely unloaded. This is efficiency because muscles use energy when opposing force.
Dr Usherwood highlighted that humans have a similar walking method to ostriches, however he emphasised that there is a contrast in foot structure, suggesting that ostrich feet are far better adapted for running.
The RVC say that improving our understanding of the walking mechanics in both humans and animals can help inform best practices for individuals learning to walk again following trauma.
The complete discussion can be heard on the BBC World Service.

Two independent vets have launched a podcast to help owners strengthen their bond with pets. Dr Maggie Roberts and Dr Vanessa Howie, who have worked in both veterinary practice and major charities, are keen to use their experience to enable people to give pets a better life.
