List of the significance (p) and effect size (h2) of the interaction effects between aerobic fitness × ACE-I/D genotype on the slope of correlations between parameters of the pathway of oxygen and power output during the pedaling phase of the exercise test. Bold underlined values met the criteria of p < 0.05. N = 44. DSpO₂ (deficit in arterial oxygen saturation).
