Describe the leg kick characteristic in stroke analysis.

• A. 4-beat kick with bent knees
• B. 6-beat kick with straight legs and knees not breaking the surface
• C. 2-beat kick
• D. 8-beat kick

Answer: (B)

Leg kick pattern in stroke analysis focuses on the beat count and how the legs move through the water. The characteristic described—a six-beat flutter kick with straight legs and knees not breaking the surface—is seen as the most efficient and consistent propulsion for freestyle and backstroke. A six-beat kick means six kicks occur per arm cycle, providing continuous thrust that pairs well with the arm pull to maintain a steady forward pace. Keeping the legs straight reduces drag from knee bend, while keeping the knees under the surface minimizes surface disturbance and turbulence, preserving a clean, streamlined position. If the kick were to break the surface or use fewer or more beats without this efficient alignment, propulsion would be less smooth and energy would be wasted through increased drag or mismatched timing.
