Differences in blood lipids and apolipoproteins between master athletes, recreational athletes and sedentary men.
OBJECTIVE
Studies related with the role of intensive and moderate training on reducing coronary heart disease (CHD) risks have revealed conflicting


RESULTS
Thus, the aim of this study was to clarify the association between long-term physical training with competitive and recreational purposes and blood lipids and apolipoproteins in the middle-aged master athletes, recreational athletes and sedentary controls.


METHODS
The association between long-term physical training and serum concentrations of lipids, lipoproteins, and apolipoproteins in the middle-aged men was investigated. Twelve male master athletes (MA), 12 male recreational athletes (RA) (>10 y), and 12 male sedentary controls (CG) participated in the study. Serum concentrations of lipids and lipoproteins were measured by enzymatic methods; apolipoproteins (ApoA1 and ApoB) and serum lipoprotein(a) Lp(a) were measured by immonoprecipitation assays.


RESULTS
TC, LDL-C, ApoA1, Lp(a) levels and LDL-C/HDL-C ratio of the 3 groups did not show any significant differences. MA and RA had significantly higher levels of VO2max, HDL-C, ApoA1/ApoB ratio; and lower values of percent body fat, resting heart rate, systolic and diastolic blood pressures, TG, ApoB and TC/HDL-C ratio than CG. We did not find any significant differences between MA and RA in any variables except for BMI and TC/HDL-C ratio.


CONCLUSIONS
Habitual physical training favorably altered serum lipid and apolipoprotein profiles. Although there was no statistical significance (except for BMI and TC/HDL-C) between MA and RA, a tendency to reduce the CHD risks was observed almost in all variables in favor of MA.
