Because the center of gravity of shorter runners is closer to the base of support (the fulcrum of the feet), which gives a higher kinetic balance than the taller ones, and this will lead to a greater ability to resist the centrifugal force, with a higher possibility of changing the direction of running in the arches, which requires a lower degree of inclination to the inside of the arch and the need for a lower foot friction component, as in the adjacent figure.

Shorter runners are often preferred to run in the brackets (or positions) for the 4x100m relay event for several reasons:1.Faster Acceleration 2.Better Baton Exchange 3.Quick Turns 4.High Cadence 5.Optimizing Strengths.For these reasons, shorter runners are often strategically placed in the initial or middle legs of the 4x100m relay, taking advantage of their acceleration and agility. However, it’s also important to note that speed and skill in baton exchanges are equally important, and a well-balanced relay team is chosen based on overall strengths and coordination.
