Figure 1.
Body composition and knee extensor torque differences between cohorts. Data include whole-body fat-free mass (FFM) (panel a), fat-free mass index (panel b), vastus lateralis thickness (panel c), and knee extensor (KE) peak torque (panel d) of younger trained (YT), younger untrained (YU), and older untrained (OU) participants. Numerical values within bars represent mean ± standard deviation values. Bars with different superscript letters indicate a significant difference between cohorts (p < 0.05).
