Abstract
Blood pressure and heart rate responses to sudden changes of gravity during exercise. Am. J. Physiol. 270 (Heart Circ. Physiol. 39): H2132-H2142, 1996.-Heart rate (HR) and blood pressure responses to sudden changes of gravity during 80. to 100-W leg exercise were studied. One group was exposed to sudden changes between 1.0 and 0 g in the head-to-foot direction (G,+), starting upright and with re-peated 30-s tilts to the supine position. Another group was exposed to sudden G,+ changes between 1.8 and 0 g in an aircraft performing parabolic flight. Arterial blood pressure at the level of the carotid (carotid distending pressure, CDP) showed a large transient increase by 27-47 mmHg when G,+ was suddenly decreased and a similar drop when G,+ was suddenly increased. HR displayed a reverse pattern with larger transients (-22 to-26 min-l) in response to G,+
