Note: Anthropometric and muscle phenotypic measurements are presented as mean ± SEM and sex differences were tested by t-test. Δ relative to control, relative improvement induced by RE training, calculated as (trained-control)/control; the numbers are median (interquartile range) and sex differences were tested by Wilcoxon Rank Sum Test. 1RM: 1 repetition maximum; ISO: Isometric muscle strength; CSA: Arm whole muscle cross-sectional area measured by MRI; VOL: Arm whole muscle volume. |
