\(C\)

Show Worked Solution

C is correct: Poor technique in weight-bearing positions creates inefficient loading patterns causing recurring wrist pain.

Other Options:

A is incorrect: Inadequate warm-up contributes to injury but doesn’t explain recurring pain specific to weight-bearing.
B is incorrect: Core strength affects overall performance but wrist pain relates more to technical execution.
D is incorrect: Lack of taping isn’t a cause – it’s absence of prevention, not source of pain.

Analyse the interrelationship between body systems when performing inefficient weightlifting technique and discuss appropriate first aid responses. (8 marks)

--- 24 WORK AREA LINES (style=lined) ---

Show Answers Only

Overview Statement

Inefficient weightlifting technique creates cascading failures across musculoskeletal, nervous, and circulatory systems.
Key relationships include biomechanical stress, pain responses, inflammatory processes requiring systematic first aid intervention.

Musculoskeletal-Nervous System Impact

Poor technique forces joints and muscles beyond safe ranges, compromising stability and alignment.
Nociceptors immediately trigger pain signals through the nervous system in response.
Protective muscle spasms develop as the body attempts to prevent further tissue damage.
The interaction reveals how biomechanical errors directly activate protective neural responses.
Immediate cessation of activity becomes essential due to these warning signals.

Circulatory-Inflammatory Response

Tissue damage initiates increased blood flow to affected areas.
Acute inflammatory responses including swelling and heat result from this vascular change.
Compression from swelling subsequently affects surrounding nerves and blood vessels.
Vascular changes therefore amplify tissue damage through this cascade effect.

First Aid Response Strategy

Primary assessment focuses on checking airway, breathing and circulation to secure vital functions.
Specific injury assessment determines whether immediate medical attention or RICER protocol is needed.
Immobilisation prevents secondary injury while maintaining vital system function.
Early ice application reduces inflammatory response by causing vasoconstriction.
Compression and elevation work together to limit swelling and fluid accumulation.

Implications and Synthesis

These interrelationships demonstrate how poor technique creates multi-system dysfunction.
First aid must address both immediate threats and specific tissue damage.
Systematic response protocols therefore prevent complications.
Early intervention significantly minimises long-term damage and recovery time.

Explain how the muscular and nervous systems are affected when a tennis player repeatedly serves with poor technique, and describe appropriate first aid responses. (5 marks)

--- 15 WORK AREA LINES (style=lined) ---

Sample Answer

Rotator cuff muscles strain from repetitive overuse and incorrect loading patterns during the serve action. This occurs because poor technique places excessive stress on shoulder stabilisers, leading to micro-tears in muscle fibres and inflammation.
Neural pathways activate continuous pain responses through the peripheral nervous system as protective feedback. This triggers muscle guarding and altered movement patterns, which creates a cycle of compensation and further tissue damage.
Localised inflammation in the shoulder region compresses surrounding nerves and blood vessels. Consequently, the player experiences referred pain down the arm and reduced range of motion, preventing normal serving mechanics.
First aid requires immediate ice application in 20-minute intervals with compression bandaging. This works by causing vasoconstriction to reduce blood flow and swelling, thereby limiting inflammatory response and pain signals.
A 48-72 hour rest period from serving is essential while maintaining gentle mobility exercises. This combination enables tissue repair without complete immobilisation, which prevents adhesions and maintains flexibility for return to play.

Analyse how multiple body systems are impacted when a long-distance runner continues competing with inefficient running style, and suggest appropriate first aid responses. (8 marks)

--- 22 WORK AREA LINES (style=lined) ---

Show Answers Only

Sample Answer

Overview Statement

Inefficient running technique creates excessive stress across multiple body systems, directly affecting performance and safety.
Key relationships include muscular fatigue, skeletal misalignment, cardiovascular strain, and appropriate first aid interventions.

Muscular-Skeletal Impact

Poor biomechanics leads to increased muscular fatigue as muscles work harder than necessary.
This results in quadriceps and calf muscles experiencing irregular loading, reducing power output.
Simultaneously, misaligned forces travel through incorrectly positioned joints.
This causes ankles, knees and hips to absorb uneven stress, increasing stress fracture risks.
The relationship shows how inefficient technique compounds damage across connected systems.

Cardiovascular-Respiratory Strain

Poor technique requires more oxygen than efficient running, forcing systems to work overtime.
This triggers unnecessarily elevated heart rate while breathing becomes laboured.
Consequently, earlier fatigue occurs, limiting endurance capacity.
This reveals the direct connection between biomechanical inefficiency and physiological stress.

First Aid Response Priorities

Immediate intervention focuses on monitoring vital signs to prevent system failure.
Checking heart rate, blood pressure and hydration enables early detection of dangerous conditions.
Secondary aid addresses specific injuries using RICER protocol for muscular strains.
This prevents further damage while managing acute injuries.

Implications and Synthesis

These relationships demonstrate how inefficient technique creates cascading system failures.
Multiple systems interact, amplifying overall stress and injury risk.
Therefore, first aid must address both immediate vital signs and specific injuries.
The significance is that proper intervention prevents serious complications from biomechanical inefficiency.

Analyse how the nervous system influences movement efficiency and discuss appropriate first aid interventions when neural responses are compromised. (8 marks)

--- 22 WORK AREA LINES (style=lined) ---

Show Answers Only

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 reduces wasted muscle activity, so running uses less energy than when contractions are poorly coordinated.
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.
