Sumario:The objective of this study is to examine whether regular physical exercise during pregnancy improves the fetal and maternal heart rate response to different intensities of acute exercise. A randomized controlled trial was conducted. Sixty-three women with healthy singleton pregnancies were analyzed (n=38 in the exercise group (EG); n = 25 in the control group CG). Women from EG participated in a supervised exercise program from 9-12 until 38-40 weeks of gestation. Maternal and fetal response were evaluated in late pregnancy (week 34.08±2.27) walking for 3 minutes at di erent intensities: light exercise (LE: 40% maternal heart rate reserve) and moderate exercise (ME: 60% maternal heart rate). The primary outcome was the fetal heart rate response after maternal exertion at both intensities. After maternal e ort, the fetuses from the EG showed lower increases in heart rate than the fetuses from the CG at both intensities (LE: EG 139.1±14.2 vs. CG: 149.0±10.5; p = 0.004) and (ME: EG: 139.9±13.5 vs. 150.9±17.9; p = 0.008). The fetuses from the EG presented a lower time to recovery than those from the CG after LE (86±104.7 sec. vs. 405.2±384.7 sec.; p = 0.000) and ME (160.4±234.3 sec. vs. 596.9±461.4 sec; p = 0.000). The program was e ective for improving maternal recovery after LE (341.2±281.6 sec. vs. 577.4±277.0 sec.; p = 0.002) and ME (525.8±309.0 sec. vs. 876.1±362.6 sec.; p = 0.000). Regular exercise during pregnancy may be associated with faster maternal and fetal recovery after maternal exertion, and with a lower increase in fetus heart rate.
