Overview: Tuffs Bed Rest Study Protocol

There were three groups in the study. One group received amino acids only; one group received an amino acid supplement plus resistance training; and one group combined the amino acid supplement with resistance training and the optimal timing between ingestion of the supplement and initiation of the exercise. It is important to note that all subjects received only 85% of their energy requirements, in order to mimic the usual depressed energy intake of astronauts.

The exercise component consisted of one-hour sessions which used all of the major muscle groups, six days per week. Sessions focused on upper body one day and lower body the next. The exercise intensity was at an active moderate/high level.
