Abstract

Some athletes suffer from exercise-induced gastrointestinal (GI) disturbances. We developed a profile of GI parameters in 10 symptomatic and 10 asymptomatic athletes both at rest and during exercise. Exercise included 90 min of cycling and running at 70% of maximal power. We measured oesophageal motility, gastro-oesophageal reflux, gastric emptying, orocaecal transit time (OCTT), intestinal permeability and intestinal glucose absorption. During cycling the number and duration of refluxes were increased, whereas gastric emptying showed no differences between rest, cycling and running. The OCTT was increased in the running trial, compared to rest (P=0.005). Also, intestinal permeability was higher in the running trial, compared to rest (P=0.008). There were no differences in intestinal glucose absorption between rest and exercise. Compared with asymptomatic athletes the symptomatic subjects had a higher intestinal permeability (P=0.001), more reflux episodes (P=0.03) and a longer duration of reflux (P<0.05) during cycling. No differences were observed at rest. In conclusion, there is no difference in GI profile between symptomatic and asymptomatic athletes at rest. During exercise, symptomatic subjects have a longer OCTT and a higher intestinal permeability, which is more pronounced during running than during cycling.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 November 2012.
All research outputs
#9,376,798
of 12,220,965 outputs
Outputs from European Journal of Applied Physiology and Occupational Physiology
#2,264
of 2,771 outputs
Outputs of similar age
#88,583
of 131,281 outputs
Outputs of similar age from European Journal of Applied Physiology and Occupational Physiology
#38
of 49 outputs
Altmetric has tracked 12,220,965 research outputs across all sources so far. This one is in the 20th percentile – i.e., 20% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,771 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.1. This one is in the 15th percentile – i.e., 15% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 131,281 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
