Figure 4. Method for Comparing the Full Walking Session to 5 Minute protocol.

(a) The range of change in the reactance measured at 5kHz and 100kHz during a continuous walking session is used to calculate β. (b) The range of the change in the reactance measured at 5kHz and 100kHz per step is used to calculate ${\widehat{h}}_{\alpha }$. (c) The mean ${\widehat{h}}_{\alpha }$ of the last 10 steps is correlated to the ratio of the range of change in the reactance measured at 5kHz and 100kHz using Pearson’s correlation
