Notes for this study:
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.
