| Sumario: | Background: In recent years high intensity interval training (HIIT) has grown in popularity. However, it rarely rep‑ resents training interventions in experimental studies in pregnant populations. Therefore, in this study we aimed to assess changes in depressive symptoms, fear of childbirth, fear of Covid‑19 and quality of life after an 8‑week super‑ vised online HIIT program, compared to an educational (self‑performed physical activity) program. Methods: We conducted a randomized control trial among 54 Caucasian women in uncomplicated, singleton preg‑ nancy (age 32 ± 4 years, 22 ± 4 week of gestation; mean ± SD). There were 34 women in the experimental group, who participated in an 8‑week high intensity interval training program (HIIT group). The comparative group was consti‑ tuted of 20 pregnant women who attended 8‑week educational program (EDU group). Results: The most important finding was that mental health improved somewhat in both groups after the interven‑ tion, but only the HIIT group improved statistically significantly. The positive trends in lowering the severity of depres‑ sive symptoms, fear of childbirth, and fear of Covid‑19 were observed in both groups. However, the positive response to the intervention was stronger in the EDU group. As a secondary outcome, there was a significant decrease in cardiores‑ piratory fitness level in the EDU group, while the HIIT group maintained unchanged level of maximal oxygen uptake. Conclusions: HIIT seems to be beneficial for women with uncomplicated pregnancies to maintain adequate quality of life and mental health. However, more research is needed to determine the effectiveness of prenatal HIIT in preg‑ nant women in various psychological conditions. Trial registration: We conducted this study in Poland, in 2021. It was approved by the Bioethics Commission at the Dis‑ trict Medical Chamber in Gdansk (KB‑8/21). The full study protocol was registered in ClinicalTrials.gov (NCT05009433). |
