Insulin levels are group medians with interquartile range in parentheses, while percent changes are given as means ± SD; n = 7 for AA group, n = 12 for RT group, and n = 12 for AART group. See Table 1 for description of study groups. P values shown represent time-by-group interactions for comparisons between end of bed rest and baseline, end of recovery and end of bed rest, end of recovery and baseline, as determined by repeated-measures ANOVA with energy intake as a covariate.
