Motion Analysis

1. Segments involved

2. Movements involved

3. Sequence of movements

4. Muscles causing movements

General Principles Smaller/lighter projectiles allow a greater number

of segments to contribute to the performanceSmaller/lighter projectiles allow for a larger k Smaller/lighter projectiles allow the smaller

segments to give greatest contribution [e.g. Shld. medial rotation + Forearm pronation]

Larger/heavier projectiles get greatest contribution from larger segments

Performance Errors: Kinetic Link

1. Segmental Positioning

2. Sequence of Movements/Timing

3. Lack of Power/Strength
