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.

The purpose of this longitudinal study was to identify factors for coronary artery disease (CAD) in a teenage population in the Netherlands from ages 13.5 to 21.5 years. In a follow-up study 93 boys and 107 girls were measured annually from 1977 to 1980, and a fifth measurement was made in 1985. The CAD factors assessed were total serum cholesterol (TC), high density lipoprotein cholesterol (HDL), TC/HDL ratio, systolic (Psyst) and diastolic (Pdiast) blood pressure, percentage body fat (percent fat) and aerobic fitness (VO2 max/BW). The results indicate that the percentage of subjects at risk for CAD are relatively low in both sexes for all factors except for percent fat. From 20 to 30% of the subjects remain in the upper half of risk factor distribution throughout the 8 years study for TC, TC/HDL, percent fat, and VO2max/BW, indicating stability during the teenage period. Because percent fat combines a high stability with relatively high mean values during the teenage period in both sexes, this parameter seems a particularly important CAD risk factor in youngsters.

In Japan, 2 approaches have been adopted to assess health and functional status in older adults. One is a battery of physical-performance tasks. The other is estimation of physical vitality using biomedical risk factors. Previous research has examined strength and direction of the relationship between functional fitness and performance on activities of daily living. Vital-age tests have most often been used to assess risk for developing a variety of age-related diseases. The present study examined interrelationships among functional fitness and vital-age scores in Japanese women (N = 129, mean age = 71.9). The functional fitness test battery consisted of arm curls, walking around 2 cones, moving beans with chopsticks, and functional reach. The vital-age test battery consisted of 6 coronary heart disease risk factors (systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, triglycerides, abdominal girth, and hematocrit) and 5 physical-performance variables (oxygen uptake and heart rate at lactate threshold, side-to-side stepping, 1-leg balance with eyes closed, and forced expiratory volume).
