C. Drinking liquids during exercise does not cause cramping.
Explanation:
During the practice of physical activities, there may actually be stiffness in the muscles and such cramp. The relationship between sodium and potassium pump is believed to be a trigger for pain through dehydration or excessive sodium loss with sweat. But this in longer workouts and when you neglect hydration or do not plan proper replacements during the race.
To avoid cramping pain you should drink plenty of fluids during exercise, replenish sodium levels during intervals during heavier workouts and when there is abundant sweating (which can be done with a sports drink), and ensure nutritional recovery. (particularly for salt) and proper rest of the muscles after intense training.
