Table 2. Heart rate data for game and training sessions. Game and training data presented as Mean ± SD with (95% confidence intervals) and [range]. Differences between game and training presented as matched-pairs comparisons (paired t-test or non-parametric Wilcoxon signed rank), effect size (Cohen’s d) and percent difference with (95% confidence intervals).
