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

CHAPTER iv: BLOOD, PLASMA AND RED‐CELL VOLUMES IN PATIENTS WITH RHEUMATOID ARTHRITIS OR IRON DEFICIENCY AND IN CONTROLS

“…The mean for the male control group was 13.7 g/lOO ml, which is of the same magnitude as the figures given by Strandell (31). He found a mean of 13.3 g/lOO ml, S D 0.92 g/lOO ml in 74 healthy men aged 30-83 years, using the same hemoglobinometry method as in this study.…”

“…A comparison with Si randell's figures (31) for THb, BV and PV has been made in the preceeding section and showed a rather close correlation.…”

“…The determinations were made at intervals of 1-2 days. (20) was replaced by an approximate formula introduced by Linderholm and later modified and discussed by Strandell (31). A recent discussion of the alveolar CO method is given by Ekelund (7).…”

Heart Rate and Work Load at Maximal Working Intensity in Old Men1

“…Heart volume was determined by X-ray in prone position, and total haemoglobin and blood volume by the alveolar carbon monoxide method. These methods were described in previous papers (32,33).…”

“…heart rate increase at heart rate 130 (St st,,,), log arterial lactate at 600 kpm/min. (log lact,,) and at heart rate 130 (log lact,,,) have been described in detail earlier (31,32,33). Log arterial lactate at maximal working intensity (log lactmax) was either measured during or immediately after exercise or estimated by a short extrapolation from submaximal up to maximal heart rates.…”
