Sample Answer
Preparation phase features:
- Nervous system processes basket location and defender positions.
- Motor cortex signals leg muscles for coordinated contraction.
- Skeletal joints flex at ankles, knees and hips.
- Muscles store elastic energy through eccentric loading.
Jump execution characteristics:
- Agonist muscles (quadriceps, gastrocnemius) contract concentrically.
- Antagonist muscles (hamstrings) relax to allow extension.
- Skeletal levers provide mechanical advantage for upward force.
- Proprioceptors relay body position information continuously.
Shot release coordination:
- Fine motor control activates arm and hand muscles.
- Skeletal alignment maintains balance during flight.
- Visual feedback guides ball trajectory.
- All systems synchronise for accurate timing.
