“…These results are perplexing, as we had expected that fetuses of mothers receiving the hand massage procedure would show a similar response to that of fetuses of mothers receiving a foot massage. Research on the effects of maternal exercise on fetal activity indicate that moderate and strenuous exercise affect the fetus differentially (Marsal, Lofgren, & Genser, 1979;Manders et al, 1997). While light exercise produces slight or no changes, moderate exercise produces increases in fetal heart rate and breathing whereas strenuous exercise produces the opposite effect.…”

“…Massage therapy has been shown to affect maternal cortisol and cathecholamine levels (see Field, 1998, for review) and may have similar physiological effects to certain forms of exercise. Exercise has been shown to affect uterine artery blood flow (Clapp, 1980;Erkkola, Pirhonen, & Kivijarvi, 1992) and fetal heart rate, breathing, and movements (Collings & Curet, 1985;Manders, Sonder, Mulder, & Visser, 1997).…”

Fetal activity during midgestation (M age=19.8 weeks) was studied in response to vibratory stimulation of the mother's abdomen (at the height of the fetal head), foot massage, hand massage, or control condition (no stimulation). Consistent with previous research conducted during midgestation, the fetuses of mothers who received two trials of 3-sec, 60-Hz vibratory stimulation did not show changes in movement. In contrast, the fetuses of mothers who received a 3-min foot massage showed greater movement than the control fetuses. However, stimulating the mother's hand (another highly innervated area) did not increase fetal activity. By late gestation (M age=35.4 weeks), vibratory stimulation resulted in increased fetal activity. These findings replicate previous research indicating that vibratory stimulation to the mother's abdomen does not elicit fetal activity until later in gestation. Furthermore, our findings indicate that stimulating the mothers' feet, but not the hands, can evoke fetal activity in midgestation.

“…We wanted to test the mother when she was moved since maternal efforts in a moderate type of exercise increase fetal heart rate, but decrease its variability and the number of body movements (Manders, Sonder, Mulder, & Visser, 1997). The end of gestation (over 37 weeks GA) also favors reduction of fetal movements since the descended fetal head often is restrained in the maternal pelvic passage, thereby minimizing variation in tactile stimulation that might be experienced by the fetus.…”

Pregnant women, carrying end of gestation fetuses (38-41 weeks gestational age) were either gently rocked in an anterior posterior plane in a rocking chair or gently swayed laterally in a garden glider. Stimulation lasted for either 5 or 26 s (R5 & R26, SW5 & SW26). Fetal heart rate (HR) (bpm) and ultrasonically detected fetal movements were recorded 26 s before and during stimulation. Heart rate data were processed two ways: (a) ANOVAs performed on average values for each group and (b) comparisons of the proportion of subjects in each group showing HR accelerative change (AC), HR decelerative change (DC), or no change (NC) using chi2 statistics. HR direction and amplitude of changes were determined with the help of a conservative procedure previously developed and fitted to multidirectional HR responses (Lecanuet, Granier-Deferre, Jacquet, & Busnel, 1992). Results of ANOVAs indicated that a 26-s rocking stimulation induced a significant average HR acceleration (4.53 bpm) compared to a nonstimulated (control) group. Five seconds of rocking had a weaker, but still significant, effect on HR acceleration, but the two swaying conditions did not reliably affect either the HR or behavioral measures. Processing data nonparametrically confirmed that R26 stimulation evoked mostly AC (72%) and identified a gradual decrement of AC and DC percentage responses from Group R5, SW26 to Group SW5 while NC percentages raised. Hypotheses concerning the target sense activated by this stimulation were considered in relation to responses to auditory stimuli.

“…A few studies found no change in FHR during or immediately after a maternal exercise session (Marsal et al 1979;Artal et al 1995;Bonnin et al 1997). Some studies found a few cases of decreased FHR immediately after a single session of maternal exercise (Jovanovic et al 1985;Watson et al 1991;Manders et al 1997). In Manders et al (1997) this bradycardia occurred at 89 and 99% of maternal maximal increase in heart rate and was accompanied by drastic attenuation in fetal HRV, along with no body and breathing movements for 20 min, while in Watson et al, the fetal HR decrease was brief and followed by increased fetal HR about 10 bpm above baseline levels (Watson et al 1991).…”
