3.1. Compliance
All 12 participants completed the study within five months and adhered to nutrition standardisation requirements. One participant had adverse responses in the passive DEHydration trial for unknown reasons and was moved into the adjacent laboratory intermittently to minimise discomfort. These data were included in the final analysis because physiological variables were collected under standardised environmental conditions and were within three SD of the mean and the range of other participants under the same trial conditions.
