Data presented a normal distribution according to the Shapiro-Wilk test, and skewness and kurtosis (z score considered: –2 to +2). Results are expressed as mean ± standard deviation for the parametric data and median and (25th and 75th) percentiles for the non-parametric data. A two-way (LV-HIIT sessions vs. time) ANOVA for repeated-measures was used to compare the PPT, PPTol, PPI, and CVJH 24-h and 48-h. Also, this statistical approach was used to compare HR and RPE responses between the LV-HIIT protocols. The degrees of freedom were adjusted in the case of sphericity assumption violation, and reported using the Greehouse-Geisser epsilon correction. Eta squared partial (η2p) was used to determine the effect size of the variance. Bonferroni’s post hoc test was used when necessary to find the significant differences. Hedges’ gav was used to determine the within-session effect size (ES) (Lakens, 2013). For Hedges’ gav, ES < 0.2 reflects a negligible difference, ≥ 0.2 and < 0.5 reflects a small difference, ≥ 0.5 and < 0.8 reflects a moderate difference, and ≥ 0.8 suggests large difference. The significance level was set at P < 0.05 for all analyses. All data were analyzed using SPSS version 22.0 for Windows (Statistical Package for Social Sciences, Chicago, IL, USA).
