“…In a longitudinal study, Dawber, Moore, and Mann (1957) showed that excess weight corrected for height carried an extra liability to coronary heart disease but they assumed without justification, that such excess of weight was primarily due to obesity. Forssman and Lindegard (1958) found their subjects to be fatter but, although they measured physical strength, which did not differ between the groups, they did not assess muscularity somatometrically. These conclusions, taken in association with those shown in Table VI, indicate that at all ages the muscular man, who is perhaps a little overweight, is particularly liable to develop coronary heart disease.…”
