During warming up, which outcome regarding muscle temperature is expected?

Muscle temperature increases, improving elasticity. Muscle temperature decreases. No change in elasticity. Elasticity decreases.

Correct Answer:

Muscle temperature increases, improving elasticity.

Explanation:

During warming up, muscle temperature increases. When muscles heat up, their tissues become more pliable and stretch more easily because enzymes work faster, blood flow rises, and the muscle-tendon unit becomes less stiff. This improved elasticity supports a greater range of motion and lowers injury risk. So the expected outcome is higher muscle temperature with greater elasticity. If temperature dropped or stayed the same, or elasticity decreased, that would not align with the warming-up effect.
