Abstract

Objectives. To study the effect of different types of sports on plasma lipid profile. Subjects and method. Fasting plasma levels of total, LDL- and HDL-cholesterol (TC, LDL-C, HDL-C), triglycerides, phospholipids, apo A-I, apo B-100, and Lp(a) were measured in 28 swimmers, 17 volleyball players and 23 soccer players, and in a control group. All subjects participated in official national competitions except the control group. The results were compared to those in a control group of 26 healthy sedentary subjects. All groups were matched according to age, body mass index and nutritional status. Cutoff points to classify subjects with high plasma concentrations of Lp(a) and LDL-C were 32 mg/dL and 128 mg/dL, respectively. For other variables the cutoff points were the third quartile values recorded in the control group, except for apo A-I and HDL-C, for which we used the first quartile values. Results. Persons who practice sports involving a high level of physical exertion (volleyball and soccer players) had a less favorable lipid profile compared to control subjects. In contrast, swimmers had a more favorable lipid profile. The odds ratio for lipid profile anomalies was significantly higher in volleyball and soccer players, and lower in swimmers. In the former two groups we observed a clear tendency toward simultaneous elevations in LDL-C, apo B-100 and Lp(a). In contrast, the opposite interaction was seen in swimmers, who had lower values for all lipids. Conclusion. Our results show that stressful physical exertion can lead to abnormalities in plasma lipid profile.
