I'm working on a project that concerns movement and the human body. Before I begin to experiment, I need an answer to a question I'm sure has an answer, but doesn't Google well.
What I need to know is firstly whether I can assume that if people have the same height, they will also have the same leg length?
Secondly, if two different people have an identical height, will they take the same amount of time to cover the same distance when running at the same speed, regardless of their unique technique for running?
An Example:
Say I'm with a friend, we're both 6 feet tall exactly, we both get on to treadmills side-by-side and set it to a speed of 7.5km/hour.
Will we be moving exactly the same body parts at the same time - will our feet land on the treadmill at the same time?
Is there a possibility that people of the same height do not have the same leg length? If so, how likely is it on average?
