Evaluation Statement
- Biomechanical principles are highly effective in improving movement efficiency.
- This is judged by their ability to reduce injury, sustain performance and optimise energy use.
- Evidence from physical activity, sport-specific skills and functional tasks shows strong success with only minor limitations.
Injury reduction and sustained movement
- Biomechanics is highly effective in lowering injury risk while enabling sustained effort.
- Evidence supporting this includes recreational running (physical activity), where correct posture and light foot strike reduce joint stress and delay fatigue.
- Similarly, when lifting (functional activity), bending at the hips with a wide base of support protects the spine.
- These examples successfully address the biomechanical principle of sustaining movement safely.
- The evidence indicates biomechanics not only prevents breakdown but also improves long-term participation.
Optimising energy and performance
- Biomechanical principles also improve efficiency by reducing wasted energy.
- A clear example is competitive swimming (sport-specific), where streamlining reduces drag and lowers fatigue.
- In tennis (sport-specific), correct force transfer during a serve generates more power with less strain.
- These applications adequately fulfil the goal of sustaining performance under pressure.
- However, effectiveness depends coaches teaching the correct technique as well as poor execution limiting benefits.
Final Evaluation
- Weighing these factors shows biomechanics is a highly effective tool across all movement types.
- While its success depends on proper teaching and practice, its strengths clearly outweigh limitations.
- The overall evaluation demonstrates biomechanics is essential for improving efficiency, performance and reducing injury. These benefits cover daily life movements as well as elite sport and recreational activity.
