A swimmer needs to reduce drag force during freestyle. Which combination of biomechanical applications would be MOST effective for safe and efficient movement through water?

  1. Streamlined body position and high elbow recovery
  2. High head position and wide arm recovery
  3. Crossed leg kick and streamlined body position
  4. Wide arm recovery and crossed leg kick
Show Answers Only

\(A\)

Show Worked Solution
  • A is correct: Streamlined body reduces frontal resistance while high elbow recovery minimises drag.

Other Options:

  • B is incorrect: High head position increases drag and disrupts body alignment.
  • C is incorrect: Crossed legs create turbulence that negates streamlining benefits.
  • D is incorrect: Both wide arm recovery and crossed legs increase water resistance.
