“…Endurance exercising is comparable to human athletes running marathons,where a prevalence of 54% of gastrointestinal signs has been reported (bleeding, abdominal cramping, nausea and diarrhoea) (Halvorsen et al 1986). Long distance exercise effects gastric and intestinal mucosa integrity following a splanchnic circulation shunt (Oktedalen et al 1992;Buchman et al 1999). A similar pathogenesis of ischaemic enteropathy could be involved in the endurance horses.…”

“…Plasma a-tocopherol concentrations increase following exercise, and can rise up to three-to four-fold approximately, regardless of duration, dose or frequency of supplementation (Buchman et al, 1998;Traber, 1999;Mastaloudis et al, 2004). Accordingly, our results showed no significant differences between supplemented and nonsupplemented sportsmen, probably due to the low vitamin E supplementation (the used enriched beverage was designed just to cover approximately 30% RDI), and also because the half-marathon is an endurance physical activity of intensity lower than other strenuous exercises like a duathlon or an ultramarathon.…”

“…Dual‐sugar tests have been used to determine exercise‐associated changes in intestinal permeability; lactulose with rhamnose or mannitol is used for small intestine, sucralose and erythritol for large intestine, and sucrose for gastric permeability . As outlined in Table (seven studies were eligible for inclusion Table S1), gastrointestinal permeability appears to increase in proportion to the magnitude of exercise, with higher body temperature and running linked with greater permeability . For example, marathon competition and running at ≥70% VO 2max , with or without heat stress, with body temperature ≥39°C, resulted in the highest reported rates of elevated small intestinal permeability .…”
