title: Physical activity and the gastrointestinal tract.
abstract: Measurement of the various gastrointestinal functions usually requires that a measuring instrument be placed in a certain position in the stomach or gut and that the instrument remains in the same position during the period of measurement. During physical activity it is often difficult to be sure that this requirement is fulfilled. This may in part be the reason why so little is known about the effects of physical activity on the gastrointestinal tract. The following article gives an overview of what is known and what has not been studied in this field. From what we already know we may conclude that these organs are only affected to a slight degree by physical activity.
