The moment the runner’s foot hits the ground is represented by the beginning of the wave. As the mass of the runner’s body accelerates toward the ground, the amount of force increases and the wave climbs. The wave then slopes down as the runner begins the motion of lifting the leg again.
What determines running speed?
Two factors that determine running speed are stride cadence and stride length. Stride cadence refers to the number of strides taken per second, and stride length refers to the distance traveled by each stride. The product of these factors gives a mathematically accurate description of running speed.
