Which injury involves muscle fibres stretched too far or torn?

• A. Tendonitis
• B. Strains
• C. Sprain
• D. Stress fracture

Answer: (B)

Muscle strains occur when muscle fibers are overstretched or torn, usually from a sudden, forceful movement or from overuse. That direct damage to the muscle fibers fits the description of “muscle fibres stretched too far or torn,” which is what a strain is.

In practice, strains can range from minor to severe, with symptoms like sharp pain during activity, tenderness, swelling, and weakness in the affected area. Management typically involves rest, protection, and gradual rehabilitation to restore strength and flexibility.

The other options don’t fit the description: tendonitis involves inflammation of a tendon, not tearing of muscle fibers; a sprain is an injury to ligaments around a joint; and a stress fracture is a bone injury from repetitive loading.
