The image below shows a tennis player preparing to return a serve.

Which biomechanical principle is this player primarily using to optimise stability?

  1. Lowering the centre of gravity and widening the base of support
  2. Narrowing the base of support to increase agility
  3. Raising the centre of gravity to improve reaction time
  4. Increasing the line of gravity outside the base of support
Show Answers Only

\(A\)

Show Worked Solution
  • A is correct: Lowered centre of gravity and widened stance maximise stability for receiving serves.

Other Options:

  • B is incorrect: Narrowing base of support decreases stability needed for powerful returns.
  • C is incorrect: Raising centre of gravity reduces stability and balance.
  • D is incorrect: Line of gravity outside base of support causes instability and falling.
