Gravity and gravidity: will microgravity assist pregnancy?

Abstract: During the third trimester of pregnancy, exercise, deep ventilation and supine position may be particularly uncomfortable for pregnant women. Reduction of fetal weight by a microgravity environment may relieve some of this discomfort. This study assessed, by means of heart rate variability (HRV), the cardiovascular adaptation to the supine posture, to relaxing respiratory exercises (deep slow breathing) and to mild and moderate lower limb exercises in pregnant women, both in a dry environment and during a head… Show more

“…These changes may be related to a state of "body preparation" for labor and also the response to compression of abdominal sympathetic ganglia and large vessels, such as aorta and both vena cavas. 17,23,26 These physiological changes occurring in pregnancy, regardless of the presence of physical exercise, can be evaluated through the results of control groups composed of pregnant women where the intervention was not applied. In this sense, Carpenter et al 26 noticed a decrease in HRV over the course of pregnancy, reflected by the decrease in RMSSD and SDRR.…”

“…And, regarding the low frequency-high frequency radio (LF/HF) ratio, Farche et al 15 found a difference between pregnant and nonpregnant women at all analyzed moments; when evaluating pregnant women who did or did not do physical activity, Satyapriya et al 19 found differences only in the 36th GW, when evaluating the pre and post intervention, in the two groups. Merati et al 17 found a difference when comparing the resting state with exercises on dry land and Nakagaki et al 23 found differences between TM2 and TM3, in the 1st, 2nd, and 3rd second (Table 3).…”
