Roach R, Koskolou M, Calbet J, Saltin B
Am J Physiol
. 1999 Feb;
276(2):H438-45.
PMID: 9950843
A universal O2 sensor presumes that compensation for impaired O2 delivery is triggered by low O2 tension, but in humans, comparisons of compensatory responses to altered arterial O2 content (CaO2)...

Aviat Space Environ Med
. 1998 Dec;
69(12):1182-5.
PMID: 9856544
Background: Acute mountain sickness (AMS) is a usually self-limiting syndrome encompassing headache, nausea and dizziness. AMS is seen in those that go from low to high altitudes too quickly, without...

Nielsen H, Madsen P, Svendsen L, Roach R, Secher N
Acta Physiol Scand
. 1998 Oct;
164(1):89-7.
PMID: 9777029
Influence of arterial oxygen pressure (PaO2) and pH on haemoglobin saturation (SaO2) and in turn on O2 uptake (VO2) was evaluated during ergometer rowing (156, 276 and 376 W; VO2max,...

Saltin B, Radegran G, Koskolou M, Roach R
Acta Physiol Scand
. 1998 May;
162(3):421-36.
PMID: 9578388
Regional limb blood flow has been measured with dilution techniques (cardio-green or thermodilution) and ultrasound Doppler. When applied to the femoral artery and vein at rest and during dynamical exercise...

Koskolou M, Roach R, Calbet J, Radegran G, Saltin B
Am J Physiol
. 1997 Nov;
273(4):H1787-93.
PMID: 9362244
We hypothesized that reducing arterial O2 content (CaO2) by lowering the hemoglobin concentration ([Hb]) would result in a higher blood flow, as observed with a low PO2, and maintenance of...

Koskolou M, Calbet J, Radegran G, Roach R
Am J Physiol
. 1997 Jun;
272(6 Pt 2):H2655-63.
PMID: 9227543
Hypoxia affects O2 transport and aerobic exercise capacity. In two previous studies, conflicting results have been reported regarding whether O2 delivery to the muscle is increased with hypoxia or whether...

Loeppky J, Icenogle M, Scotto P, Robergs R, Hinghofer-Szalkay H, Roach R
Respir Physiol
. 1997 Mar;
107(3):231-9.
PMID: 9128904
To investigate the possible effect of hypobaria on ventilation (VE) at high altitude, we exposed nine men to three conditions for 10 h in a chamber on separate occasions at...

Roach R, Loeppky J, Icenogle M
J Appl Physiol (1985)
. 1996 Nov;
81(5):1908-10.
PMID: 8941508
Acute mountain sickness (AMS) strikes those in the mountains who go too high too fast. Although AMS has been long assumed to be due solely to the hypoxia of high...

Loeppky J, Scotto P, Roach R
Aviat Space Environ Med
. 1996 Nov;
67(11):1019-22.
PMID: 8908337
Background: Some reports claim that ventilation (VE) is greater in human subjects in normobaric hypoxia than at altitude following an equivalent drop in inspired PO2 (PIO2). It has been suggested...

West J Med
. 1995 Aug;
163(2):117-21.
PMID: 7571557
The effect of previous physical conditioning on young well-conditioned mountaineers in relationship to acquiring acute mountain sickness is controversial. Data show both increased and decreased effects on the incidence of...
