Gastrointestinal symptoms among long-distance runners are among the most annoying and performance-affecting problems some runners complain of stomach pain or sudden cramps that may be accompanied by nausea at times runners feel an urgent need to use the toilet which causes major disruption in running
Why do these symptoms occur during long-distance running
During long runs a large part of the blood flow is directed to the active muscles this happens at the expense of internal organs like the stomach and intestines which receive less blood and thus become more sensitive and weaker in digestion add to that the constant body vibration and internal pressure caused by running movements which irritate the digestive system
Does the pre-run diet play a role in these symptoms
