Efeitos do exercício aeróbio ou da ingestão de suco de beterraba sobre o consumo alimentar, a antropometria e a composição corporal de mulheres hipertensas após a menopausa

Abstract

Postmenopause is associated with hormonal changes that promote alterations in body composition and increase cardiovascular risk. In this context, this study aimed to evaluate the effects of a 10-day intervention with beetroot juice, physical exercise, or a control condition on dietary intake, anthropometric parameters, and body composition in postmenopausal women with hypertension. This randomized clinical trial included 53 participants allocated to three groups: beetroot juice (n = 17), physical exercise (n = 18), and control (n = 18). Anthropometric measurements, body composition assessed by bioelectrical impedance analysis, and dietary intake evaluated through 24-hour dietary recalls were analyzed. The exercise group showed reductions in waist circumference (p = 0.027) and abdominal circumference (p = 0.001), with no changes in body mass or body mass index. The beetroot juice group showed no significant changes in the evaluated parameters. No differences in dietary intake were observed among the groups, although energy and lipid intake increased over time. It was concluded that physical exercise promoted favorable changes in indicators of central adiposity, whereas beetroot juice supplementation produced no detectable effects on body composition or dietary intake during the study period.
