  1. Results are based on 2 × 2 mixed-model ANOVA. Time and group were modeled as fixed factors. Time was characterized by the levels HDBR7 and HDBR49. Group was entered with two levels, comparing CTR (n = 5) to bed rest plus resistive exercise irrespective of the exercise protocol (pooled data from RE and RVE, n = 11).
  2. df1, numerator degrees of freedom; df2, denominator degrees of freedom; F, F-statistic; p, p-value.
