Which technique would be most effective for a swimmer to reduce drag forces during their stroke?

  2. Increasing stroke rate to move through water faster
  3. Using a wider arm stroke to catch more water
  4. Breathing more frequently to maintain oxygen levels

\(A\)

Show Worked Solution
  • A is correct: Streamlined body alignment reduces drag by minimising resistance to water flow.

Other Options:

  • B is incorrect: Higher stroke rate doesn’t reduce drag forces, may actually increase them.
  • C is incorrect: Wider arm strokes create more drag, opposing efficient movement.
  • D is incorrect: Breathing frequency affects performance but not drag reduction directly.
