Adding alanylglutamine at two concentrations to drinking water (1g per 500mL or 2g per 500mL) provided during a 40 minute competitive basketball game appeared to increase post-game reaction time and shooting skill at the lower but not higher dose, whereas self-reported fatigue was reduced only at the higher concentration relative to pure water.

Overall water consumption averaged 1.55 ± 0.43 liters in all groups, and changes in body weight or water losses did not differ between groups. Power output (jump test) did not differ between any hydrated group, but was expectedly reduced in the group without water.

In subjects who reported to the lab in a dehydrated state who then, 45 minutes prior to an exercise test (75% VO2 max until fatigue), rehydrated with water or one of two solutions containing alanylglutamine (0.05g/kg or 0.2g/kg) noted that while, relative to the trial with no rehydration there was a relative increase in performance change, but overall supplementation did not improve overall time until fatigue relative to water.

Relative to the same protocol of which water was used, alanylglutamine failed to differntially affect cardiovascular parameters and other hormones and cytokines did not differ from water.
