Velocity is the change in distance over the time it takes to for the change in distance to occur. For example if I were to start running from stationary position (Initial Distance ‘Di’) and run 40 yards (Final Distance ‘Df’) in 4.4 seconds my average velocity for the entire run would be the change in distance (40yards) divided by the time it took to travel that distance (4.4 seconds).
Physics (Impulse)
Impulse is a very important equation to understand for optimization of performance. The equation itself is derived from the Force equation (F = MA)
The steps to get the impulse equation are as follows:
Physics (Force)
Force
Force is the product of mass and acceleration.
Force = mass * acceleration
Force is a vector quality, meaning it has both magnitude (how much force) and direction (which way the force is going).
Force = mass * acceleration
Velocity Based Training (What and Why)
Before we can dive into the “how to” and the “when to”, it is probably wise to first discuss the “what is” and “why to”, of velocity based training.
