Interpretive Summary: The consumption of orange juice associated to regular aerobic exercises reduced body fat and improved the physical performance in previously sedentary middle aged women. Also, the regular intake of orange juice decreased bad cholesterol (LDL-C) and increased good cholesterol (HDL-C) in the blood of these women.
Technical Abstract: This study evaluated the influence of regular consumption of orange juice associated with aerobic exercise on the lipid profile of middle aged women, previously sedentary. Twenty-six women, 30 to 55 years old, volunteered to consume orange juice daily for 3 months and participate in an aerobic training three times a week for the same period. They were separated randomly into two groups: (1) aerobic exercise training (control group) or (2) aerobic training plus a daily dose of 500mL of orange juice (experimental group). After 3 months of aerobic training, the control group reduced weight (-2.5%) and fat mass (-15%), while women treated with exercise plus orange juice decreased fat mass (-11%), but did not change the weight. The consumption of orange juice increased dietary intake of vitamin C (126%) and folate (61%). Serum LDL-C decreased 15%, and HDL-C increased by 18% in the women treated with orange juice plus exercise, but not in control group. Blood lactate dropped 27% in experimental group, but no change was observed in the control. Therefore, the regular intake of orange juice associated with aerobic exercise showed a positive effect on serum lipid profile and improved physical performance level in previously sedentary middle aged women.
