Acceleration is determined by the formula of change in velocity over the change in time.
The high knee run into sprint is a variation used here at BPT for acceleration training.
This drill is an advanced version of the falling start, which requires athletes to adjust their torso and shin angles with speed and direction to gain acceleration. If you think about situations in sports where this pattern takes place, there are two that come to mind.
1. A baseball pitcher starting in a wind-up must start tall in a single leg stance and then transition with force into a horizontal direction to deliver a pitch.
2. A soccer player who is jogging while a play is being executed and has to hit a lane with force transitions from an upright position of the jog to a more horizontal position of the acceleration.
