How can a diver relieve cramps in their calf?

Bending the toe of the fin towards the knee is an effective way to relieve cramps in the calf. This action mimics a stretching motion that helps to alleviate muscle tension in the calf area. When a diver bends their toes upwards, it extends the calf muscle, promoting relaxation and potentially reducing the cramping sensation.

Sitting down on the ocean floor or attempting to stretch the leg straight may not provide adequate relief since these positions might not target the muscle contraction effectively. Holding the foot flat does not provide the right leverage needed to stretch the calf muscle, which is crucial in relieving cramps. Thus, bending the toe towards the knee facilitates the necessary stretch and alleviation of muscle cramps.
