Study Notes
Movement Starts and Ends
- Good positioning cannot be reclaimed once a movement has begun, or entered the "tunnel of load"
- Starting position and ending position are the most important, middle movement is less important
Tunnel of Load
- Entering the tunnel of load is like entering a specific movement phase
- Once you enter the tunnel, your position at the start determines your position at the finish
- If you start in a bad position, you cannot correct it during the movement
Prime Movers
- The shoulder and hip are the primary movers in many athletic movements
- The goal of many sports is to create effective hip extension
One Joint Rule
- The body can be viewed as having one hip and one shoulder joint
- This simplifies movement analysis by focusing on stability and ideal hip motion
- Introducing spinal flexion or extension (breaking neutral) creates multiple "virtual joints", making movement control more difficult
- Spinal deviations also cause "force bleed" (loss of power)
Importance of Neutral Spine
- Maintaining a neutral spine creates a stable platform for the shoulder and allows for efficient power generation
- Breaking neutral leads to internal rotation of the shoulder and a loss of control
- The body can be viewed as a rigid, stable structure with a consistent joint on both sides
