Abstract
Background: Physical activity is an important part of healthy lifestyle and should be continued during low-risk pregnancy. Several studies have suggested that most pregnant women had no contraindications to perform exercises. The aim of the study was to assess the acute effect of an exercise test up to refusal and a chronic impact of an 8-week HIIT program on albuminuria and kidney function in the 2nd and 3rd trimester of pregnancy. Material and Methods: A group of 36 pregnant women was studied. At the beginning of the study, all participants had normal kidney function and albuminuria at rest. Nineteen women participated in an 8-week HIIT program (HIIT group), and seventeen in an educational program (EDU group). Before and after the training or education programs, a progressive exercise test up to volitional exhaustion on a cycloergometer was conducted. Several biochemical measurements were performed to assess changes in the kidney function. Results: After a short exercise test, some unexpected findings were observed: the fractional excretion of urea and uric acid increased (FeUrea from 41.25 to 50.05%; FeUA from 7.18 to 8.04%), and serum uric acid significantly decreased (sUA from 3.35 to 3.28mg/dL). Although the 8-week HIIT program had no impact on the kidney function at rest, the interesting finding was that albuminuria significantly increased only in the EDU group. Conclusion: Changes in the kidney function after a short very intense exercise in pregnancy were typical of healthy women, but there was no negative impact on markers of renal hypoperfusion. The supervised HIIT program during pregnancy had no negative impact on the kidney function.
