Changes in physiological variables from pre- to post-training.

The values presented are means ± SD. F and P values were obtained by Two-Way ANOVA (2 × 4: time × training group) with repeated measures. POL, polarized training group; HIIT, High intensity interval training group; THR, threshold training group; HVT, high volume training group; VO₂, oxygen uptake; HR, heart rate; LA_peak, peak blood lactate concentration; ^*p < 0.05; ^**p < 0.01; ^***p < 0.001 significant difference within groups from pre- to post-training. ^†p < 0.05; ^†††p < 0.001 significant different from POL training group.^‡p < 0.05 significant different from HIIT training group. ^aMain effect between pre- and post-test. ^bMain effect between training groups. ^ctime × training group interactive effect.
