Metabolic responses during distance running
Abstract
examinations were made on highly trained distance runners to determine the changes in blood lactate during prolonged, exhaus-tive running at varied intensities and durations. Laboratory tests included maximal and submaximal treadmill running for from 5 to 120 min. Respiratory exchange and heart rate were determined during all trials. Lactic acid determinations were also made after competitive distance races that ranged from 1.61 to 42 km. There was an inverse curvilinear relationship between the length of the competitive race and blood lactate concentration. When the oxygen requirement of the run was less than 70y0 of the runner’s aerobic capacity, little or no increase in blood lactate was ob-served. During 2 hr of running that required between 55 and 67y0 of max vo2, a very slight increase in lactic acid was found. Highly trained distance runners were found capable of utilizing more than 90 o/;i of max voz (70 ml/kg-mm) for 25-30 min with only mod-

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.
