Comparisons of the thickness values associated with spatiotemporal intersegmental coordination (IC). Participants walked according to a sinusoidal speed-changing protocol for time periods of 30 s, 60 s, and 120 s period, respectively. SY, sedentary young (white bars); AY, active young (black bars); and AE, active elderly adults (gray bars), respectively. ^#p < 0.05 and ^†p < 0.01, respectively. Values are means ± standard deviations
