Statistics
Anthropometric and baseline exercise capacity measurements are presented as means with standard deviation and compared using a one-way ANOVA. Proportions are expressed in percentages and compared by Pearson’s chi-squared test if model assumptions were met and otherwise by Fisher’s exact test.Changes in exercise capacity and steady-state VOFinally, potential genotype-specific differences in average power output and relative power output during the exercise training sessions were assessed by a one-way ANOVA (D/D vs I/D vs I/I). Power output is presented as means with standard deviations. The level of statistical significance was set at
