What causes muscle strains?

What causes muscle strains?

• A. Overstretching or forcing a muscle to contract against excessive resistance.
• B. Poor hydration or electrolyte imbalance.
• C. Nutritional deficiency.
• D. Repetitive microtrauma without acute overload.

Answer: (A)

Muscle strains occur when muscle fibers are stressed beyond their capacity, either by being stretched too far or by being asked to contract with more force than the muscle can safely generate. This mechanical overload causes microscopic tears in the muscle tissue, typically after a sudden, explosive movement or a rapid change in direction. That is why overstretching or forcing a contraction against excessive resistance best explains how a strain develops. While poor hydration or electrolyte imbalance can lead to cramps and fatigue, and nutritional deficiencies can affect performance, they don’t directly cause the tearing of muscle fibers seen in a strain. Repetitive microtrauma without a single overload event is more associated with overuse injuries than with an acute strain from a single heavy load.
