To maintain optimal buoyancy while floating, a swimmer should focus on which muscular action?

Relaxing all muscles to conserve energy
Contracting leg muscles to keep feet at the surface
Engaging abdominal muscles to maintain core position
Tensing shoulder muscles to keep arms extended

\(C\)

Show Worked Solution

C is correct: Contracting abdominal muscles keeps the core (naval region) at the surface, maintaining streamlined position and optimal buoyancy.

Other Options:

A is incorrect: Complete muscle relaxation often leads to poor flotation position
B is incorrect: Leg muscle tension alone doesn’t address core stability needed for flotation.
D is incorrect: Shoulder tension doesn’t contribute significantly to maintaining buoyancy.
