PrepTest 88, Section 3, Question 1
One reason swimming immediately after eating is thought to be dangerous is that it could cause muscle cramps. But there is no reason to believe this. Muscle cramps are usually caused by muscle fatigue and dehydration, which are unrelated to eating. Reduced blood flow to muscles during digestion might also be a cause, though this is disputed. In any case, not enough blood goes to the stomach to aid in digestion after a meal to reduce blood flow to muscles.
