^{a), b), c)}Represent the significant effect in two-way repeated ANOVA P< 0.05, 0.01, and 0.001.

^{e), f)}Represent the significant effect in paired t-test P< 0.05, 0.01, and 0.001.

^g)Represents the significant effect in independent t-test P< 0.05.

No marking is not significant. REG, regular exercise group; CON, control group; WHR, waist to hip ratio; BMI, body mass index.
