The peak oxygen uptake (VO2) of 199 boys and 164 girls (mean age 13.2±1.3 yrs) was examined in relation to their body fatness, blood pressure, and serum cholesterol level. Peak VO2 was significantly correlated with skinfold thickness in both sexes (range r = −0.41 to −0.56). When the common effects of skinfold thickness were removed, no significant relationships were observed between peak VO2 and either serum cholesterol or blood pressure. The habitual physical activity (HPA) of 92 boys and 132 girls (mean age 13.0+1.3 yrs) was examined in relation to their body fatness, blood pressure, and serum cholesterol. No significant relationships were observed. The results of this study indicate that although skinfold thickness is negatively related to peak VO2, favorable relationships between children’s peak VO2 or HPA and either blood pressure or serum cholesterol remain to be proven.
