Watenpaugh D, Ballard R, Breit G, Hargens A
Aviat Space Environ Med
. 1999 May;
70(5):522-6.
PMID: 10332951
Background: Exercise during spaceflight helps prevent musculoskeletal and cardiovascular deconditioning to Earth gravity. This report evaluates the aerobic and anaerobic exercise stimulus provided by self-generated lower body negative pressure. Methods:...

Ballard R, Watenpaugh D, Breit G, Murthy G, Holley D, Hargens A
J Appl Physiol (1985)
. 1998 Jun;
84(6):1976-81.
PMID: 9609792
To assess the usefulness of intramuscular pressure (IMP) measurement for studying muscle function during gait, IMP was recorded in the soleus and tibialis anterior muscles of 10 volunteers during treadmill...

Watenpaugh D, Breit G, Ballard R, Hargens A
Aviat Space Environ Med
. 1997 Sep;
68(9):858-62.
PMID: 9293356
Background: Acute fluid shifts initiate chronic cardiovascular acclimation to altered posture or gravity. Hypothesis: We hypothesized that neck volume increases with acute tilt from vertical to horizontal and head-down positions,...

Breit G, GROSS J, Watenpaugh D, Chance B, Hargens A
J Bone Joint Surg Am
. 1997 Jun;
79(6):838-43.
PMID: 9199380
Variations in the levels of muscle hemoglobin and of myoglobin oxygen saturation can be detected non-invasively with near-infrared spectroscopy. This technique could be applied to the diagnosis of chronic compartment...

Breit G, Whalen R
Med Sci Sports Exerc
. 1997 Apr;
29(4):540-7.
PMID: 9107638
Investigation of the influence of human physical activity on bone functional adaptation requires long-term histories of gait-related ground reaction force (GRF). Towards a simpler portable GRF measurement, we hypothesized that:...

Chang D, Breit G, Styf J, Hargens A
Am J Physiol
. 1996 Oct;
271(4 Pt 2):R961-6.
PMID: 8897988
Our objective was to understand how weight bearing with varying gravitational fields affects blood perfusion in the sole of the foot. Human subjects underwent whole body tilting at four angles:...

Stout M, Watenpaugh D, Breit G, Hargens A
Aviat Space Environ Med
. 1995 Sep;
66(9):872-5.
PMID: 7487826
Background: The cutaneous microcirculation vasodilates during acute 6 degrees head-down tilt (HDT, simulated microgravity) relative to upright conditions, more in the lower body than in the upper body. Hypothesis: We...

Watenpaugh D, Ballard R, Breit G, BERNAUER E, Blomqvist C, Hargens A
J Gravit Physiol
. 1995 Jan;
2(1):P21-2.
PMID: 11538917
Elevated calf compliance may contribute to orthostatic intolerance following space flight and bed rest. Calf venous compliance is measured conventionally with venous occulusion plethysmography in supine subjects. With this well-established...

Int J Microcirc Clin Exp
. 1995 Jan;

PMID: 7558623
Periodic fluctuations, regular slow-wave flowmotion, were induced in the skeletal muscle of six mature anesthetized New Zealand White rabbits by acute femoral artery pressure reduction from a median control value...

Ann Vasc Surg
. 1994 Nov;
8(6):543-8.
PMID: 7865392
Leg compression devices have been used extensively by patients to combat chronic venous insufficiency and by astronauts to counteract orthostatic intolerance following spaceflight. However, the effects of elastic and inelastic...
