People who exercise very hard may be prone to acute or chronic gut issues, researchers reported.
A systematic review suggested that exercise intensity was a key regulator of gastric emptying rate, with higher intensity exercise (≥70% peak power output) causing the greatest disturbance to gastric motility, according to Ricardo J.S. Costa, MD, of Monash University in Victoria, Australia, and colleagues.
However, steady state moderate exercise (60-70% peak power output or 66% VO2max equivalent) did not appear to influence gastric emptying and intestinal transit compared with rest in well-trained individuals, they wrote online in Alimentary Pharmacology and Therapeutics.
Additionally, they found that the impact of high-intensity exercise on gastric motility appeared to be ephemeral, as the intensity of prior exercise had a negligible effect on post-exercise gastric emptying rate of a glucose solution.
"Understanding the effect of prolonged strenuous exercise on gastrointestinal motility is important since the consumption of foods/fluids during exercise aids in the maintenance of blood glucoseconcentration and euhydration, aimed at attenuating fatigue and enhancing exercise performance," Costa stated.
