Figure 5. Boxplots showing spread of DNAm biomarkers between male controls (n = 149) and male body builders (n = 66) in the Polish study. (A) DNAmFitAge is younger on average in the male body builders, (B) DNAmVO2max is fitter on average in the male body builders, (C) FitAge Acceleration and (D) DNAmGaitspeed are suggestively improved in body builders but not significantly different at 0.05.
