Question

select the correct answer.
john stretched while his muscles were cold. which negative effect could occur?

a. blood might not flow to his limbs.

b. his strength could decrease quickly.

c. he could injure or pull a muscle.

d. oxygen might not reach his muscles.

Explanation:

When muscles are cold, they are less flexible. Stretching cold muscles increases the risk of muscle injury or strain because the muscles aren't warmed up and ready to be stretched, making them more prone to tearing or pulling. Option A is incorrect as blood flow to limbs isn't directly affected by stretching cold muscles in this way. Option B: Strength decrease isn't a direct immediate effect of stretching cold muscles. Option D: Oxygen reaching muscles is related to circulation and respiration, not directly to stretching cold muscles. So the correct answer is C.

Answer:

C. He could injure or pull a muscle.
