ANOVA: analysis of variance; CI: confidence interval; G: group; T × G: time × group interaction; T: time; TC: thigh circumference; ηp2: partial eta squared. †††: Significant main effect or interaction effect from repeated-measures ANOVA (p < 0.001). **: Significant within-group pre–post difference (p < 0.01). ***: Significant within-group pre–post difference (p < 0.001). ###: Significant between-group difference determined by an independent-samples t-test (p < 0.001).
