Sample Answer
Power Clean:
- Multiple joints allow explosive triple extension; muscles generate rapid force; nerves coordinate fast recruitment.
- Nervous system activates fast-twitch fibres while muscles contract powerfully through skeletal joint range.
- Complex nerve pathways coordinate multiple muscle groups across key skeletal positions.
- Nervous system integrates movement while muscles transfer force through skeletal chain.
- Skeletal and muscular systems provide dynamic stability guided by neural feedback.
Deadlift:
- Hip and knee joints provide base; muscles generate steady force; nerves recruit steadily.
- Simple nerve pathways control gradual muscle tension through fixed skeletal path.
- Nervous system maintains consistent muscle activation along stable joint angles.
- Skeletal system provides rigid base while muscles control eccentric phase.
- Limited joint movement requires steady muscle tension and basic neural control.
