Sample Answer
Overview Statement
- The nervous system controls muscle coordination and sensory feedback, directly affecting movement efficiency. Key relationships include neural-muscle communication, proprioceptive feedback, and compromised function requiring first aid.
Neural-Muscle Coordination
- The nervous system controls which muscles work together, directly influencing movement efficiency.
- Neural coordination enables muscles to activate at precise times and use energy effectively.
- During running, the nervous system activates hip muscles before foot contact while relaxing opposing muscles.
- This creates 25% more efficient running than uncoordinated muscle contractions.
- This pattern shows how the nervous system is essential for efficient movement.
Proprioceptive Feedback System
- Body position sensors provide continuous feedback that connects to balance and coordination.
- The nervous system processes information from sensors to make instant adjustments.
- Balance sensors in ears and position sensors in joints help athletes maintain centre of gravity within 2cm of optimal position.
- This reveals the connection between nervous feedback and precise movement efficiency.
First Aid When Neural Function Compromised
- When the nervous system is damaged, immediate intervention prevents further injury and enables recovery.
- Recognising nerve problems leads to proper emergency response protecting immediate safety.
- Athletes experiencing tingling, coordination loss, or irregular muscle function require immediate activity cessation.
- TOTAPS assessment focusing on sensation testing prevents worsening of nerve injuries.
Implications and Synthesis
- These relationships show the nervous system orchestrates all efficient movement through coordination and feedback.
- When neural function is compromised, movement efficiency decreases dramatically.
- Therefore, first aid protocols must prioritise neural assessment and protection.
- The significance is that proper intervention can prevent permanent damage and preserve movement capacity.
