Eight subjects performed continuous 30-min arm exercises with an increase in intensity every 10 min (30, 60, and 90 W). The loads corresponded to 29 +\/- 1, 48 +\/- 2, and 78 +\/- 4% (means +\/- SE) of the maximal O2 uptake (VO2max 2.13 +\/- 0.08 l\/min) during arm exercise. VO2max during arm exercise was 61 +\/- 1.7% of that during leg exercise. The dye concentration was analyzed in blood samples from three arm veins, two ipsi- and one contralateral, at shoulder level. Corresponding dye concentrations in both ipsilateral veins and a stable concentration difference between ipsi- and contralateral veins were achieved. Total arm blood flow was calculated to be 0.21 +\/- 0.04 l\/min at rest and 2.43 +\/- 0.14 l\/min at 90 W. Arm O2 uptake rose from 9 +\/- 2 to 323 +\/- 21 ml\/min. Arm blood flow and O2 uptake each correlated linearly with both work load (r = 0.98) and pulmonary O2 uptake (r greater than or equal to 0.98). Mechanical efficiency for the arm and body was 34-44 and 16-19%, respectively. We conclude that arm blood flow can be determined by continuous infusion of indocyanine green. <\/jats:p>","DOI":"10.1152\/jappl.1991.70.2.928","type":"journal-article","created":{"date-parts":[[2017,12,21]],"date-time":"2017-12-21T22:12:38Z","timestamp":1513894358000},"page":"928-933","source":"Crossref","is-referenced-by-count":28,"title":["Arm blood flow at rest and during arm exercise"],"prefix":"10.1152","volume":"70","author":[{"given":"G.","family":"Ahlborg","sequence":"first","affiliation":[{"name":"Department of Clinical Physiology, Sodersjukhuset, Stockholm, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Jensen-Urstad","sequence":"additional","affiliation":[{"name":"Department of Clinical Physiology, Sodersjukhuset, Stockholm, Sweden."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","container-title":["Journal of Applied Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/jappl.1991.70.2.928","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,8]],"date-time":"2019-09-08T12:52:55Z","timestamp":1567947175000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/jappl.1991.70.2.928"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,2,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1991,2,1]]}},"alternative-id":["10.1152\/jappl.1991.70.2.928"],"URL":"https:\/\/doi.org\/10.1152\/jappl.1991.70.2.928","relation":{},"ISSN":["8750-7587","1522-1601"],"issn-type":[{"value":"8750-7587","type":"print"},{"value":"1522-1601","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,2,1]]}}}
