Maximal heart rate during work in older men
Abstract
Nine 56–68-year-old male subjects performed muscular work up to maximal loads on a bicycle ergometer while breathing both ambient air and oxygen. Heart rate increased to an average maximum of 163/min. The maximal O 2 intake averaged 2.24 l/min. and the blood lactic acid concentration 85 mg/100 ml. In no case was the maximal heart rate higher when breathing O 2 than when breathing air. This low maximal heart rate in older people probably limits the capacity for O 2 intake. Four subjects were able to work for about 1 hour without any sign of exhaustion on a work load requiring an O 2 consumption of about 50% of their maximal aerobic work capacity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“Several investigators also found that the maximum heart rate decreased with age in normal subjects (ROBINSON et al., 1938;STRAND, 1952;ASTRAND et al., 1959;ASTRAND et at., 1964).”

In the citing paper
“Aging diminishes maximum oxygen uptake capacity by decreasing maximal cardiac output and this effect seems to be partly due to decreased maximal heart rate (AsTRAND et al.,1959;HANSEN et a1.,1968).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
