Metabolic and cardiovascular responses to exercise with caffeine
Open accessAbstract
The effect of caffeine on circulation and metabolism was studied during a discontinuous maximal oxygen uptake (VO2 max) test on a bicycle ergometer. Eight male subjects were chosen for their minimal use of caffeine of which six normally did not ingest caffeinated beverages. Two caffeinated and two decaffeinated (control) trials were administered to each subject following double-blind and counterbalanced testing procedures. One hour before exercise, subjects ingested decaffeinated coffee with or without 350 mg of caffeine anhydrous added. Cardiac output (Q) was measured by a C02 rebreathing technique. Compared to control trials, caffeine increased the VO2 max by an average of 140ml min−1 (p <0-0·5)l. In addition, during caffeine trials, the average maximal heart rate (HR max) was elevated by 5 beats min−1 (p<0·01). There were no other statistically significant changes in metabolic (VO2 and R) and cardiovascular (Q, HR, SV and (a-v) 02 diff) variables during either submaximal or maximal exercise. Performance, as measured by total exercise time on the VO2 max test, was not significantly different (p>0·05). It was concluded that caffeine has a small physiological but a statistically significant effect on VQ2 max and HR max. During submaximal exercise, caffeine did not significantly effect the cardiovascular system.

From Caffeine delays autonomic recovery following acute exercise (2015) · cites this paper as [29]
In the Results and Conclusions (page not provided), the paper reports increased maximal oxygen consumption after caffeine. It also explicitly says exercise time to exhaustion was unchanged, so it does not support the claimed prolongation. (LLM, conf=0.91)

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.
