ObjectivesTo systematically review studies evaluating one or more components of physical fitness (PF) in pregnant women, to answer two research questions: (1) What tests have been employed to assess PF in pregnant women? and (2) What is the validity and reliability of these tests and their relationship with maternal and neonatal health?DesignA systematic review.Data sourcesPubMed and Web of Science.Eligibility criteriaOriginal English or Spanish full-text articles in a group of healthy pregnant women which at least one component of PF was assessed (field based or laboratory tests).ResultsA total of 149 articles containing a sum of 191 fitness tests were included. Among the 191 fitness tests, 99 (ie, 52%) assessed cardiorespiratory fitness through 75 different protocols, 28 (15%) assessed muscular fitness through 16 different protocols, 14 (7%) assessed flexibility through 13 different protocols, 45 (24%) assessed balance through 40 different protocols, 2 assessed speed with the same protocol and 3 were multidimensional tests using one protocol. A total of 19 articles with 23 tests (13%) assessed either validity (n=4), reliability (n=6) or the relationship of PF with maternal and neonatal health (n=16).ConclusionPhysical fitness has been assessed through a wide variety of protocols, mostly lacking validity and reliability data, and no consensus exists on the most suitable fitness tests to be performed during pregnancy.PROSPERO registration numberCRD42018117554.

“…They found a significant increase in maternal parameters (systolic BP, diastolic BP, and HR) during exercise, with a return to baseline after rest; however, they did not find changes in the PI, RI, or S/D ratio values in the evaluated placental areas. Neither fetal Doppler nor fetal HR was evaluated [10].…”

Background: Studies on physical activity during pregnancy and its impact on mother and fetus are still limited. International protocols consider only aerobic exercise and fail to provide information about other modalities such as isometric exercise. Isometric exercise promotes cardiorespiratory resistance and muscle strengthening, but it is rarely tested on pregnant women because it increases maternal blood pressure and can subsequently affect placental circulation. Objective: To evaluate maternal and fetal response of low-risk pregnant women undergoing isometric testing through a Doppler velocimetry study. Methodology: A cross-sectional, experimental study was performed on 46 healthy pregnant women (gestational age between 26 and 36 weeks) who underwent isometric testing. This testing was performed using a handgrip dynamometer to measure maternal and fetal hemodynamic parameters before, during, and after isometric testing. Results: There was a significant increase in systolic blood pressure (BP; pre-isometrics 113.13 ± 9.92 mmHg, during isometrics 117.13 ± 10.24 mmHg, and post-isometrics 112.43 ± 9.87 mmHg, p < 0.001) and heart rate (HR; pre-isometrics 87.52 ± 14.10 bpm, during isometrics 97.61 ± 14.83 bpm, and post-isometrics 85.13 ± 13.24 bpm, p < 0.001). There were significant decreases in the pulsatility index (PI; pre-isometrics 0.63 ± 0.15, during isometrics 0.56 ± 0.15, and post-isometrics 0.65 ± 0.17, p = 0.001), resistance index (RI; pre-isometrics 0.44 ± 0.08, during isometrics 0.40 ± 0.07, and post-isometrics 0.45 ± 0.08, p = 0.001), and systolic/diastolic (S/D) ratio (pre-isometrics 1.81 ± 0.26, during isometrics 1.69 ± 0.24, and post-isometrics 1.85 ± 0.29, p < 0.001) of the left uterine artery (UA). These results showed significant changes only during the isometric exercise, and not between the pre-and post-isometric exercises. There were no significant differences in fetal parameters when the results before, during, and after the isometric test were compared. Conclusion: Isometric testing had no repercussions for fetal hemodynamics in healthy low-risk pregnant women.

“…IHG has the potential to identify maladaptive responses to a dynamic arterial load in the vasculature that are not apparent at rest, and has previously been used as a predictive tool to identify those at risk of hypertensive disorders. Responses to isometric contraction have been investigated during pregnancy, as well as in non‐pregnant women who experienced hypertensive pregnancy earlier in life.…”
