HIIT, high-intensity interval training; p, probability; ${\eta }_p^{\mathit{\text{2}}}$, effect size partial eta-square; T, global effect of time; G, global effect of group; T × G, global effect of Time × Group; F, degrees of freedom.

^*P < 0.05,

^**P < 0.01 for the difference between groups.

^aRefers to Circuit_HIIT minus Circuit_combined.

^b± 90% CI: add or subtract this number from the mean effect to obtain the 90% confidence intervals for the true difference.
