Baseline, before exercise (control); 24 hours post-exercise; PON1a, paraoxonase 1 activity; PON1c, paraoxonase 1 concentration; Apo A1, apolipoprotein A1; HDL, high-density lipoprotein; HDLc, high-density lipoprotein cholesterol; TG, triglyericide concentration. VLDL, very low-density lipoprotein; LDL, low-density lipoprotein, oLDL, oxidized low-density lipoprotein.

Significance compared to baseline (control): *P < 0.05.
