According to some models, tryptophan delays the onset of fatigue. Conversely, in other models, this amino acid is implicated in generating fatigue.

Each volunteer did two trials, one with tryptophan supplementation (TRP) and the other with placebo (PLB).

Blood pressure, pupil size and haematocrit values were also monitored.
