Which biomechanical principle is most important when a swimmer aims to move faster through water?

\(B\)

Show Worked Solution

B is correct: Reducing drag directly addresses the force opposing forward motion in water, allowing swimmers to move faster with less energy expenditure.

Other options:

A is incorrect: Increasing base of support relates to stability on solid ground and is not applicable to swimming.
C is incorrect: Raising the centre of gravity would create poor body position in water. Swimmers need horizontal alignment with high hips to minimise resistance.
D is incorrect: Increasing joint angles creates more drag as swimmers need to keep limb alignment close to the body’s centre.
