Which is a single-leg exercise included in knee injury prevention programs?

• A. DL squat
• B. SL squat
• C. Bridges
• D. Prone Plank

Answer: (B)

Emphasizing control and alignment of the knee under load, knee injury prevention programs rely on unilateral (single-leg) training to challenge balance, hip stability, and neuromuscular control exactly where many injuries occur during sports. A single-leg squat fits this purpose because it demands the entire chain to work on one leg: the glutes, hip abductors, and external rotators must engage to keep the knee from collapsing inward, while the trunk remains stable. This helps reinforce proper knee tracking over the foot, reduces valgus stress, and improves the athlete’s ability to absorb and control forces during landing or cutting. Loading each leg independently also reveals asymmetries or weakness that two-legged movements can mask, making the single-leg squat a practical tool for identifying and correcting movement faults before they contribute to injury. It mirrors functional tasks athletes perform, so gains transfer to real sports demands. Other options don’t target this unilateral, knee-alignment-focused challenge as directly. A two-legged squat still distributes load between both legs and can mask limb imbalances. Bridges primarily train hip extensors and glute activation without stressing knee control in a stance that challenges knee alignment. A prone plank emphasizes core stability in a supine-to-prone position with minimal knee loading, so it doesn’t trains knee mechanics under functional load.
