In tennis, which muscles are listed as core muscles?

• A. Quadriceps
• B. Rectus Abdominis and Transversus Abdominis
• C. Biceps
• D. Trapezius

Answer: (B)

Core muscles stabilize the spine and pelvis and enable efficient power transfer between the legs and upper body. In tennis, that stability lets you rotate smoothly and generate racket speed while protecting the back during rapid twists and movements. The Rectus Abdominis helps flex the trunk, contributing to controlled bending and brisk torso movement. The Transversus Abdominis sits deeper, wrapping around the abdomen like a corset to brace the spine and increase intra-abdominal pressure during dynamic actions. Together, these abdominal muscles provide the trunk stability and rotational control essential for serves, forehands, backhands, and quick directional changes. The Quadriceps are knee extensors, the Biceps flex the elbow, and the Trapezius moves the shoulder blades and upper back, none of which are the primary stabilizers of the spine like these abdominal muscles.
