Parametric data presented as mean (standard deviation) and non-parametric (NP) data presented as median (interquartile range). Physiological outcomes compared with Two-way repeated measures ANOVA. Verification Phase Duration was compared with Wilcoxon Test. CPET - Running Cardiopulmonary Exercise Test. GKT – Graded Karate Test. VER – Verification Phase. Δ% - Percentage difference of Verification phase and Incremental maximal outcomes [(Incremental-Verification)/Incremental]. ES – Effect size (Cohen’s f for physiological outcomes and r (Z√n) for verification phase duration). * denotes significant difference (p ≤ 0.05). T*P – Test and phase interaction.
