Abstract

This study describes the distribution of blood lipid concentrations and examines relationships among training volume (TV, kilometers per week), peak oxygen consumption ((V)over dotO(2peak)), body fatness, and blood lipid concentrations in 48 male and 22 female distance runners, aged 10-19 years. Comparisons were made to a current reference sample and clinical cut-off points. Relationships were assessed by partial correlations allowing for age and sexual maturity. Compared to reference median values, mean concentrationsof total cholesterol (P=0.07) and low density lipoprotein-cholesterol (P<0.005) were higher, while high density lipoprotein-cholesterol (HDL-C; P=0.24) was comparable in male distance runners. Blood lipid concentrations in female distance runners were comparable to reference median values. Althoughsome subjects had dyslipidemic values, most possessed clinically normal concentrations of blood lipids. The TV was weakly correlated with blood lipidconcentrations, but may have been indirectly related with HDL-C through its relationship with (V)over dotO(2peak) in males runners (r=0.32). In female runners, correlations between sum of skinfolds' (SSF), the trunk-to-extremity ratio (TER) and blood lipid concentrations were low (r=0.16 to -0.27),with one exception (TER and HDL-C, r=-0.60). The most consistent relationships existed among TV, (V)over dotO(2peak), SSF, and HDL-C with partial correlations ranging from low (r=0.10 TV) to moderate (r=0.37 SSF, r=0.41 (V)over dotO(2peak)). The correlation between (V)over dotO(2peak) and HDL-C remained significant after allowing for age and SSF, while the partial correlation between SSF and HDL-C, allowing for age and (V)over dotO(2peak), was reduced and not significant (r=-0.19, P=0.20). In female runners, the correlation between (V)over dotO(2peak) and HDL-C was r=0.32, whereas the partialcorrelation between SSF and HDLC, allowing for age and (V)over dotO(2peak), was r=0.00. Blood lipid concentrations of young male distance runners were not, on average, different to the general population of the youth of the United States. The young distance runners showed considerable heterogeneityin blood lipid phenotypes, including dyslipidemic values. The results highlight the complex relationships among TV, (V)over dotO(2peak), body fat andHDL-C, and indicate the unique contribution of (V)over dotO(2peak) as an important predictor of HDL-C in young distance runners.
