To relieve a cramp in the calf

• A. Bend the toe of the fin toward the knee to stretch the muscle
• B. Stand up and walk
• C. Massage the calf vigorously
• D. Drink water and rest

Answer: (A)

Calf cramps respond best to stretching the muscle to relax the spasm. Bending the toe of the fin toward the knee actively dorsiflexes the ankle, lengthening the gastrocnemius and soleus. That direct stretch interrupts the cramp by pulling the calf fibers back to their resting length, improving blood flow and reducing the involuntary contraction.

Other options are less effective in the moment: standing up and walking isn’t practical with fins in the water and can disrupt control; massaging the calf vigorously can irritate the muscle and may not relieve the cramp; drinking water and resting help with prevention and recovery but don’t provide immediate cramp relief once it starts.
