3.2. Experiment 2
Mauchly’s test indicated that the assumption of sphericity had not been violated (χ22 = 0.097, P = 0.99). Two-way repeated ANOVA revealed that walking was significantly affected by time (F 2,28 = 116, P< 0.0001) (Fig. 3). However, the effects of group (F 1,14 = 0.36, P = 0.55) and the interaction between the two factors (F 2,28 = 0.03, P = 0.96) were not significant.
