Which of the following is a common risk factor for ACL injuries?

• A. Neuromuscular imbalances
• B. Excellent vertical jump height
• C. Adequate hydration status
• D. Regular warm-up routine.

Answer: (A)

Neuromuscular control around the knee and hip is crucial for safe dynamic movement. When those systems are imbalanced—such as weak hamstrings or glutes relative to the quadriceps, poor core stability, or faulty landing mechanics—the knee can collapse inward or rotate in ways that place extra stress on the ACL during cutting, deceleration, or landing. This abnormal loading increases the risk of ACL injury, and these imbalances are common yet modifiable through targeted strength and neuromuscular training, making them a frequent risk factor you’ll see addressed in prevention programs. In contrast, excellent vertical jump height doesn’t by itself indicate a higher injury risk; it reflects power capability rather than a predisposition to ligament injury. Adequate hydration and a regular warm-up are protective factors that help reduce injury risk, rather than increasing it.
