Which assessment is used to identify left-right muscular balances and weaknesses and is typically performed after a light warm-up?

• A. Functional Movement Screen
• B. Sit and Reach
• C. Skinfold
• D. Sprint Test

Answer: (A)

Left-right muscular balance and weakness are best identified with the Functional Movement Screen. This screening tool is designed to assess movement quality across several fundamental patterns and to reveal asymmetries between the left and right sides, signaling imbalances or neuromuscular control issues that could lead to injury if not addressed. It’s typically performed after a light warm-up so the body is ready to move but not fatigued, which helps observers see genuine movement patterns rather than stiffness or fatigue masking weaknesses. The screen includes several movements scored for form and symmetry, making side-to-side differences the key factor in identifying imbalances. By contrast, sit-and-reach measures flexibility, skinfold tests body fat, and sprint tests speed, none of which specifically identify left-right balance or weaknesses.
