Tipton C, Monnin K, Hall M, Sebastian L
Aviat Space Environ Med
. 1998 Apr;
69(3):267-76.
PMID: 9549563
Background: Although humans have experienced microgravity since 1961, it is unknown whether PaO2 or PaCO2 will change in humans or in animals exposed to similar conditions. Reports from subjects participating...

Tipton C, Sebastian L
J Appl Physiol (1985)
. 1997 May;
82(5):1607-15.
PMID: 9134911
Post-spaceflight results and findings from humans and rodents after conditions of bed rest or simulated microgravity indicate maximum exercise performance is significantly compromised. However, the chronic administration of dobutamine (a...

Woodman C, Sebastian L, Tipton C
J Appl Physiol (1985)
. 1995 Nov;
79(5):1762-8.
PMID: 8594039
Rats exposed to simulated conditions of microgravity by head-down suspension (HDS) exhibit reductions in aerobic capacity. This may be due to an impaired ability to augment cardiac output and to...

Tipton C, Sebastian L, Edwards P, Moran M
J Gravit Physiol
. 1995 Jan;
2(1):P62-3.
PMID: 11538935
Measurements from mission specialists after space flights or from subjects subjected to head down tilt experiments have demonstrated a decrease in exercise performance. Similar decreases have been reported for rats...

Woodman C, Monnin K, Sebastian L, Tipton C
J Appl Physiol (1985)
. 1993 Apr;
74(4):1941-7.
PMID: 8514715
Head-down suspension (HDS) of rats has evolved as a useful model for the simulation of a microgravity environment. Previous HDS experiments with rats have shown an impaired capacity to perform...

Woodman C, Stump C, Sebastian L, Tipton C
Aviat Space Environ Med
. 1992 Mar;
63(3):193-9.
PMID: 1567320
Results from previous studies have shown that the reduction in maximal oxygen consumption (VO2max) with simulated microgravity is attenuated in chemically sympathectomized rats. To determine the contributions of the catecholamines...

Tipton C, Sebastian L, Overton J, Woodman C, Williams S
J Appl Physiol (1985)
. 1991 Dec;
71(6):2206-10.
PMID: 1778914
Studies with male spontaneously hypertensive rats (SHR) were initiated to determine the hemodynamic relationships associated with the lower resting caudal artery systolic blood pressure (SBP) of endurance-trained SHR populations. After...

Woodman C, Stump C, Stump J, Sebastian L, Rahman Z, Tipton C
J Appl Physiol (1985)
. 1991 Sep;
71(3):1005-14.
PMID: 1757295
Maximum oxygen consumption (VO2max) has been shown to be reduced after periods of simulated weightlessness. To assess the role of the sympathetic nervous system in these reductions, Sprague-Dawley rats were...
