Which activity is NOT an example of knee injury prevention program activities?

• A. Nordic hamstring exercise
• B. Lunges
• C. Box jumps
• D. Prone Plank

Answer: (C)

Knee injury prevention programs emphasize neuromuscular training to improve control, alignment, and strength around the knee during dynamic tasks like landing and cutting. The Nordic hamstring exercise provides controlled eccentric hamstring loading that supports knee stability and helps prevent hamstring and ACL-related injuries. Lunges build functional strength and improve knee tracking and stability in the sagittal and frontal planes, aiding proper knee alignment during movement. A prone plank enhances core stability, which supports trunk control and reduces compensatory knee valgus during dynamic tasks. Box jumps, while useful for power, are high-impact plyometrics that impose substantial knee loading and require advanced technique; they are not a standard, core component of knee injury prevention programs and are less suitable as a base exercise for reducing knee injury risk.
