- Biomechanics reduces injury risk by analysing technique and correcting inefficient movement. This occurs because poor technique creates unnecessary stress on joints and muscles.
- At the same time, biomechanics improves sustained movement by making actions more energy-efficient. This leads to lower fatigue and better long-term performance.
Example 1 – Tennis serve
- Correct weight transfer from the back foot to the front foot distributes forces evenly.
- This helps to generate momentum with less strain on the shoulder.
- This mechanism results in improved serve power while reducing overuse injuries.
Example 2 – Soccer free kick
- Positioning the non-kicking foot beside the ball keeps balance and stability. This produces a solid base of support, reducing the chance of falling or not timing the kick well.
- Striking the ball with correct body alignment reduces twisting forces at the hip and knee. As a consequence, injury risk decreases.
- At the same time, this interaction allows more efficient transfer of force through the leg, creating sustained power and accuracy in repeated kicks.
