The effect of HIIT duration approached significance (F(4,127) = 2.401, p = 0.053, η 2 p G = 0.065, d ≈ 0.52).
The effect of HIIT duration approached significance (F(4,127) = 2.401, p = 0.053, η 2 p G = 0.065, d ≈ 0.52).
The main effect of sex was marginally non-significant (F(1,127) = 3.717, p = 0.056, η 2 p G = 0.022, d ≈ 0.30).
Although a decreasing trend was observed, no significant pre–post or post–follow-up changes were detected in either sex (all p = 1.000), and no differences were found compared with control groups (all p = 1.000).
