Science of Running: Understanding Stride Rate and Stride Length

Science of Running: Understanding Stride Rate and Stride Length: "This simple equation is a staple in sprinting and biomechanics material. It simply means that to see a change in speed you’ve either got to increase the ground you cover (stride length) or increase your turnover (stride frequency) or some combination of the two. The bottom line is that something has to change. But what is it that changes when we go faster?"
