Biochemical measurements at maximal exercise (mean ± SD).

Biochemical measurements	Before		Bout		After
	Sedentary group (S)	Active group (PA)	Sedentary group (S)	Active group (PA)	Sedentary group (S)	Active group (PA)
PON (U/L)
ARE (U/mL)
FRAP
TBARS (mM/L)
UA (mM/L)
TBil (M/L)
TChol (mM/L)
HDL-C (mM/L)

PON/HDL-C
ARE/HDL-C

Biochemical measurements were performed in the plasma obtained from sedentary (S) and active (PA) subjects before, at the bout of, and after maximal exercise on treadmill.
FRAP: ferric reducing activity of plasma, TBARS: thiobarbituric acid reaction substances, UA: uric acid, TBil: total bilirubin, TChol: total cholesterol, HDL-C: high density lipoprotein cholesterol, LDL-C: low density lipoprotein cholesterol, TG: triglycerides, PON: paraoxonase activity, and ARE: arylesterase activity; PON/HDL-C ratio; ARE/HDL-C ratio.
*Statistical significance of difference versus respective value “before,” .
All differences between S and PA subjects were not statistically significant.
