Which activity is a hamstring strengthening exercise used in knee injury prevention programs?

• A. Lunges
• B. Dynamic calf stretch
• C. Prone Plank
• D. Nordic hamstring exercise

Answer: (D)

This question tests which exercise provides targeted hamstring strengthening through eccentric loading, a key element in knee injury prevention programs. The Nordic hamstring exercise does exactly that: kneeling with ankles secured, you slowly lower your torso forward while the hamstrings lengthen under control to resist the fall. This high-load eccentric work lengthens the hamstrings under a functional knee position and has consistently been shown to reduce hamstring strain injuries, making it a staple in injury-prevention protocols for athletes. Other options don’t focus on this specific eccentric hamstring loading. Lunges mainly strengthen the quadriceps and hip extensors, dynamic calf stretches improve flexibility rather than strengthen the hamstrings, and a prone plank targets core stability rather than the hamstrings.
