Fig 1. Significant increases of cfDNA levels after the 12^th exercise compared to baseline levels.

(A) Fold changes of cfDNA concentrations after each strength exercise (1–16) compared to baseline levels across all types of training (CT, HT and DT) and at both monitoring points in time (1^st and 12^th day). Means (circles) and 95% CIs are presented. (B) Fold changes of cfDNA concentrations after each strength exercise (1–16) compared to baseline levels shown separately for CT, HT and DT group.
