Secher. Restricted postexercise pulmonary diffusion capacity and central blood volume depletion. J. Appl. Physiol. 83(1): 11\u201317, 1997.\u2014Pulmonary diffusion capacity for carbon monoxide (Dl <jats:sub>CO<\/jats:sub>), regional electrical impedance (Z<jats:sub>0<\/jats:sub>), and the distribution of technetium-99m-labeled erythrocytes together with concentration of plasma atrial natriuretic peptide (ANP) were determined before and after a 6-min \u201call-out\u201d row in nine oarsmen and in six control subjects. Two and one-half hours after exercise in the upright seated position, Dl <jats:sub>CO<\/jats:sub> was reduced by 6 (\u22122 to 21; median and range) %, the thoracic-to-thigh electrical impedance ratio (Z<jats:sub>0 thorax<\/jats:sub>\/Z<jats:sub>0 thigh<\/jats:sub>) rose by 14 (\u22121 to 29) %, paralleled by a 7 (\u22123 to 11) % decrease and a 3 (\u22125 to 12) % increase in the thoracic and thigh blood volume, respectively. These responses were associated with a decrease in the plasma ANP concentration from 15 (13\u201331) to 12 (9\u201327) pmol\/l ( P &lt; 0.05). Similarly, in the supine position, Z<jats:sub>0 thorax<\/jats:sub>\/Z<jats:sub>0 thigh<\/jats:sub>increased by 10 (\u22125 to 28) % when Dl <jats:sub>CO<\/jats:sub> was reduced 12 (6\u201326) % ( P &lt; 0.05), whereas Dl <jats:sub>CO<\/jats:sub>remained stable in the control group. The increase in Z<jats:sub>0 thorax<\/jats:sub>\/Z<jats:sub>0 thigh<\/jats:sub>and the corresponding redistribution of the blood volume in both body positions show that approximately one-half of the postexercise reduction of Dl <jats:sub>CO<\/jats:sub> is explained by a decrease in the pulmonary blood volume. The role of a reduced postexercise central blood volume is underscored by the lower plasma ANP, which aids in upregulating the blood volume after exercise in athletes. <\/jats:p>","DOI":"10.1152\/jappl.1997.83.1.11","type":"journal-article","created":{"date-parts":[[2017,12,22]],"date-time":"2017-12-22T03:38:02Z","timestamp":1513913882000},"page":"11-17","source":"Crossref","is-referenced-by-count":52,"title":["Restricted postexercise pulmonary diffusion capacity  and central blood volume depletion"],"prefix":"10.1152","volume":"83","author":[{"given":"Birgitte","family":"Hanel","sequence":"first","affiliation":[{"name":"Departments of Clinical Physiology, Nuclear Medicine, and Anesthesia,  Copenhagen Muscle Research Center, Rigshospitalet, and Department of Physiology, Panum Institute, University of Copenhagen, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Inge","family":"Teunissen","sequence":"additional","affiliation":[{"name":"Departments of Clinical Physiology, Nuclear Medicine, and Anesthesia,  Copenhagen Muscle Research Center, Rigshospitalet, and Department of Physiology, Panum Institute, University of Copenhagen, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Rab\u00f8l","sequence":"additional","affiliation":[{"name":"Departments of Clinical Physiology, Nuclear Medicine, and Anesthesia,  Copenhagen Muscle Research Center, Rigshospitalet, and Department of Physiology, Panum Institute, University of Copenhagen, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f8rgen","family":"Warberg","sequence":"additional","affiliation":[{"name":"Departments of Clinical Physiology, Nuclear Medicine, and Anesthesia,  Copenhagen Muscle Research Center, Rigshospitalet, and Department of Physiology, Panum Institute, University of Copenhagen, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Niels H.","family":"Secher","sequence":"additional","affiliation":[{"name":"Departments of Clinical Physiology, Nuclear Medicine, and Anesthesia,  Copenhagen Muscle Research Center, Rigshospitalet, and Department of Physiology, Panum Institute, University of Copenhagen, DK-2100 Copenhagen \u00d8, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","reference":[{"key":"B1","first-page":"435","volume":"16","author":"Bardy A.","year":"1975","journal-title":"J.
