All data are presented as mean (standard deviation) unless otherwise specified. Twenty-one of the 22 participants, who completed the 6-month exercise program, were successfully genotyped. BL= baseline; VO2Max = maximum rate of oxygen uptake. P value indicates significance level of differences between ε4 carriers and non- ε4 carriers.
