Acceleration can be defined as overcoming inertia to move as fast as possible.
4 types of Acceleration can be performed:
- Deadstarts overcome a resting inertia as quickly as possible. Think of going from 0-60MPH as fast as possible.
- Momentum-Starts overcome a constant inertia. Think of moving at 50MPH (constant inertia) and then accelerating on the highway to 80MPH to pass another vehicle.
- Coil Starts allow the body to load or coil first to capture elastic energy before accelerating in a specific direction (i.e. like a golf swing or throw)
- Reactive Starts is acceleration in a specific direction that is triggered by an environmental cue (i.e. coach yelling go at an unspecified time)
To accelerate well:
- nerves need to depolarize and repolarize quickly
- high inter/intramuscular coordination
- muscle must concentrically produce force quickly
- fascia and skin must be able to tolerate high forces (collagen and elastin).
