Effect of exercise on mouth-to-cecum transit in trained athletes : A case against the role of runners' abdominal bouncing

摘要: The role of exercise on the gastrointestinal motor function and in particular transit time is a matter hard debate. Numerous studies past have failed to demonstrate consistent effect short term untrained subjects trained athletes. It has been, however, suggested that running, with its constant jostling abdomen, may different than performed stationary setting. To examine running time, 8 healthy male runners ingested lactulose meal assigned rest or separate days. Exercise consisted 9.6 km an hour, while exhaled gas was sampled every 10 minutes for volume, minute ventilation hydrogen concentration. mean O2 consumption 36.8 ml/min/kg during session 4.7 period. Post rise concentration occurred at 85 +/- 25.1 84 18.1 resting sessions respectively (p = 0.732). On basis present data we conclude (1) mouth-to-cecum not affected by intense athletes; (2) bouncing abdominal content case probably does change time; finally, (3) impact moderate influenced subject's fitness state.
