Minerals have two classifications: major minerals and trace minerals.
Major Minerals: are needed in large amounts.
Trace Minerals: are needed in small amounts.
After the first few meters of acceleration, your torso moves from a forward lean to a vertical position as you reach your top speed. Once at top speed, your goal is to minimize contact with the ground by getting your feet down quickly and driving the ground away. Slower sprinters often land their feet too far ahead from their hip (~12 inches), whereas faster sprinters land with their feet closer (~6 inches). For maximum speed, it is best to have your feet on the ground as little as possible (⬇️ braking force) while applying maximum amount of force during extension (⬆️ propulsive force).
