Interrelationships between metabolic and cardiorespiratory health were examined in 350 healthy adults. Four principal components accounted for 66.7% of the variance in 172 males (M) and for 62.4% in 178 females (F). Factor 1, "obesity," related to body mass index, abdominal circumference, total skinfold thickness, and (M only) abdominal/hip circumference ratio. Factor 2, "cardiovascular fitness," had loadings from resting heart rate and PWC150/kg. Factors 3 and 4 were related to total cholesterol and HDL-cholesterol, respectively (plus blood pressures, particularly in F). Factor 1 was linked to caffeine consumption and to exercise frequency (F) or perceived intensity (M). Factor 2 was linked to perceptions of activity relative to others (M and F) and to the intensity of activity (M only). Factors 3 and 4 were associated with perceived fitness and physical activity relative to others. Because perceptions of physical activity and fitness lack consistency, it is suggested that health be judged more directly from simple measures of health related fitness that require little subject cooperation. Key words: caffeine consumption, cardiorespiratory fitness, gender differences, health related fitness, metabolic fitness, perceived activity

Abstract The effects of the Friend and Rauscher leukemia viruses on the marrow and spleen colony-forming unit compartments have been studied. It was found that the two viruses produced qualitatively similar but quantitatively different effects relative to each other. Comparison of the effects of the individual virus on spleen with those on the marrow also showed striking differences. In the spleen by 14 days after infection with either virus the CFU compartment was grossly enlarged. In the marrow of the Friend-infected mouse the CFU number was not significantly different from normal, and in the Rauscher-infected mouse there was a 50% drop in marrow CFU. Measurement of the F factor showed that infection by either virus resulted in colony-forming units that were deficient as compared to the normal in their ability to successfully "seed" in the spleens of irradiated normal recipients, with the greater depression in F factor being found in cells obtained from spleen tissue. These results indicate that in both cases the nature of the host tissue (marrow versus spleen) exerts a significant modifying effect on the expression of the virus action, and also suggest that the pluripotent colony-forming unit may be a target cell for these viruses.
