|Glutamine prevented a rise in intestinal permeability as measured by the urinary excretion ratio of lactulose and rhamnose (L/R ratio). The L/R ratio was higher in the PLA trial compared with rest and GLN trials. *P < 0.05, statistically significant from the rest trial; **P < 0.05, statistically significant from the PLA. Data are means ± SD, n = 8.|
"Each exercise trial consisted of a 60-min treadmill run at 65–70% of V̇ in an environmental chamber set at 30°C and a humidity range of 12–20%."
