Figure 7. Neuromuscular dysfunction correlates with skeletal muscle atrophy in elderly men. (A,C) Graphs showing the correlation between muscle cross-sectional area (CSA) and CMAP negative peak amplitude in vastus lateralis (A) and tibialis anterior (C) from adult (i.e 20-35 years) and elderly (i.e >65 years) men. (B,D) CMAP negative peak amplitude and muscle size in vastus lateralis (B) and tibialis anterior (D). For all graphs n=9-18 per group. * p<0.05 ** p<0.01 *** p<0.001 with a one-way ANOVA test.
