ACE genotype difference for training-induced effects on aerobic muscle metabolism during interval exercise. Bar graph of the mean ± SD of interval training-induced effects per ACE-I/D genotype (i.e., after vs. before 8 weeks of interval-type training) for parameters characterizing perfusion-related aerobic muscle function (A) and cardiovascular function (B) during interval exercise. Note the tendency for ACE I/D genotypes related to differences in training effects on the AUC of SmO₂ deficit and aspects of cardiovascular functioning during exercise. +, p < 0.10; *, p < 0.05. $, (for post- vs. pre-, meaning pre- versus post-training intervention).
