Sample Answer
Force application:
- Muscles generate force from springboard compression
- Joint angles optimise force generation through legs and arms
- Force direction affects safe water entry angle
- Core muscles stabilise body position during force production
Fluid mechanics:
- Body position minimises surface area for water entry
- Arms aligned to create entry pathway
- Head position between arms reduces impact forces
- Controlled entry angle reduces unsafe deceleration forces
Musculoskeletal considerations:
- Joint alignment maintains safe force absorption
- Muscle tension protects joints during water entry
- Coordinated muscle action maintains streamlined position
- Core stability protects spine during entry
