چکیده

Background: occult (i.e., non-visible) gastrointestinal (gi) bleeding is a well-recognized complication that can occur during vigorous endurance physical exertion, especially in the heat. objectives: the purpose of this study was to investigate the incidence of gi bleeding during a non-impact (cycling) prolonged race (161-km) in the heat. methods: twenty-five experienced cyclists (21 males and 4 females, 49 ± 9 y, 83.7 ± 14.8 kg) were completed a summer 161-km cycling event. following the race, participants were given a fecal occult blood test and were instructed to retrieve their first bowel movement. results: mean race dry air and wet bulb globe temperature (wbgt) were 36.0 ± 5.2°c, and 31.8 ± 3.6°c, respectively. of the 25 subjects, two (8%) produced positive results for fecal occult blood while an additional two (16%) experienced constipation, hard stools, diarrhea or vomiting. conclusions: these data showed a low incidence of gi complaints and occult bleeding during a prolonged cycling event in the heat, indicating the low-impact exercise such as cycling may lessen some of the occult gi bleeding previously reported in distance running in the heat.
