Abstract
Diet and exercise are the main modifiable factors for cardiovascular disease and may be particularly important in older adults. We investigated the effects of fasting during 12 weeks of multicomponent training in the context of the aging process in physically active post-menopausal women. Method: 25 women (60.6 ± 8.9 years) were randomized into two groups: fed (FED, n=12) or fasted (FASTED, n=13) and submitted to multicomponent training. The participants underwent anthropometric, body composition, blood pressure, biochemical blood and physical fitness assessments. Results: There was a reduction in both groups for waist circumference [FED: 100.4±6.8 and 99.1±7.1 cm before and after the intervention, respectively; F = 4.214, p = 0.048; FASTED: 93.1±10.2 and 92.2±8.4 cm before and after the intervention, respectively; p = 0.039]. No significant changes were observed for the other outcomes. Discussion: The current research results, the first in the context of aging, agree with previous studies that analyzed chronic effects of fasting, showing that fasted exercise training did not improve anthropometric measurements, body composition, or blood markers compared to the fed condition after long-term exercise training. Together, these findings suggest that fasting during multicomponent training does not affect health parameters in physically active post-menopausal women.
