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.
