Figure 5. Soleus (A) and tibialis anterior (B) ΔF outcomes in control and vibration conditions for older and young adults.

Note that, for soleus, ΔF was reduced during the vibration compared to the control condition, similarly between older and young adults. For tibialis anterior, ΔF was reduced in older adults during the vibration condition, but to a smaller magnitude than young adults (i.e. condition by age interaction). The mean (black circle) and 95% confidence interval are offset to the left. Individual data points (average ΔF per participant) are coloured by participants. pps, peaks per second.
