The serum α-tocopherol concentrations (normalised for triacylglycerol and total cholesterol concentrations) measured at baseline and at 12 weeks in the control group (CG), vitamin E supplementation group (SG), walking group (WG) and vitamin E plus walking group (WSG). Data are means ± SEM and time-group interactions are the main influencing factors (P = 0.001, Two-factor ANOVA). **Significantly different from the baseline value in the same group (paired Student’s t test, P < 0.01).
