Heart Volume and its Relation to Anthropometric Data in Old Men Compared with Young Men¹

Total Haemoglobin, Blood Volume and Haemoglobin Concentration at Rest and Circulatory Adaptation During Exercise in Relation to Some Anthropometric Data in Old Men Compared with Young Men1

“…The almost identical correlation coefficients with heart volume and total haemoglobin for W,,, and W,,, have already been mentioned in the previous paper (29). The correlation coefficients with HR,, (-0.56*** and -0.33** respectively, n = 71) and HR,,, (-0.46*** and -0.25*) were somewhat lower for Wl,o, but the differences were not of probable significance (tested after conversion to z), nor were the differences in regression coefficients.…”

“…Relation to heart volume. The correlation with heart volume in the present material after effects of weight and height are taken into account might be ascribed to varying degree of physical training or possibly to dispositional variations in the relationship between weight, height and the size of the cardiovascular system (compare the discussion in the previous paper (29).…”

“…Seventy-four healthy men aged 30 -83 years were studied. The selection of these men was described in a previous paper (29) in which also some aspects of the material were discussed.…”

“…The methods used but not described in the present study, including statistical calculations, were discussed in the previous paper (29).…”

“…W,,, was therefore used instead of W,,, in the multiple regression analysis. A more complete description of the test was given in previous reports (28,29). W,,, and W,,, are estimates of the oxygen pulse during exercise a t these heart rates.…”
