Cardiorespiratory Fitness (VO 2 max) In the within-group analysis, EG1 showed a significant increase in VO 2 max from pre- to post-test (Δ = +2.23 mL·kg −1 ·min −1 ; 95% CI (1.06, 3.40); p = 0.001; and dz = 0.87), CG exhibited a positive trend (Δ = +1.23; 95% CI (−0.04, 2.50); p = 0.056; and dz = 0.45), and EG2 showed a small, non-significant improvement (Δ = +0.55; 95% CI (−0.37, 1.48); p = 0.225; and dz = 0.28) ( Figure 2 ).
