Physiological Effects of Centrifuge-Simulated Suborbital Spaceflight.
Smith TG, Pollock RD, Britton JK, Green NDC, Hodkinson PD, Mitchell SJ, Stevenson AT. Smith TG, et al. Aerosp Med Hum Perform. 2022 Dec 1;93(12):830-839. doi: 10.3357/AMHP.6153.2022. Aerosp Med Hum Perform. 2022. PMID: 36757241
Respiratory and visual symptoms were common, with 88% of subjects reporting greyout and 29% reporting blackout. There was one episode of G-induced loss of consciousness (G-LOC).DISCUSSION: Suborbital acceleration profiles are generally well tolerated but are not physiologi …

Logistic risk model for the unique effects of inherent aerobic capacity on +Gz tolerance before and after simulated weightlessness.
Ludwig DA, Convertino VA, Goldwater DJ, Sandler H. Ludwig DA, et al. Aviat Space Environ Med. 1987 Nov;58(11):1057-61. Aviat Space Environ Med. 1987. PMID: 3689269
After adjusting for pre-bed-rest tolerance time, none of the profile variables remained in the risk equation for post-bed-rest tolerance greyout. However, prior to bed rest, risk of greyout could be predicted with 91% accuracy. All of the profile variables except we …
