The effect of eight weeks of aerobic exercise with orange juice consumption on liver enzymes and fasting blood glucose in overweight middle-aged women

Overweight and obesity are among the most important public health concerns associated with multiple negative health outcomes. Physical activity is an important lifestyle behavior that helps to regulate body weight. ALSO, Physical activity reduce the risk of diabetes, cardiovascular disease and cancer, middle-aged men and women are now recommended to maintain a healthy body weight, avoid overweight and obesity, and maintain a good serum lipid profile. In addition, studies have shown the effect of orange juice consumption on improving lipid profile and metabolic syndrome index. The aim of the present study was to investigate the effect of 8 weeks of aerobic training combined with orange juice consumption on the concentration of liver enzymes and fasting blood sugar in overweight middle-aged women (30-59 years).

This study was performed as a voluntary clinical trial on 60 overweight women (BMI≥ 28) age between 30 and 59 years from the Kan Health Center. Randomly divided into 4 groups (n = 15) (exercise) (exercise + orange juice) (orange juice) and (control) respectively. At the beginning and the end of the study, blood samples were taken after 12 hours fasting. Supplementation and Exercise The day after blood sampling, the supplemented groups received 500 ml of orange juice daily for 8 weeks and three with weekly, the control group did not participate in any training program. The endurance training protocol was performed on treadmill running and walking for eight weeks and three sessions per week with intensity of 45 to 98% of maximum heart rate. Training sessions lasted from 28 to 38 minutes and were warmed and cooled for 18 and 7 minutes, respectively, before and after each training session. All data were entered into SPSS version 24 for statistical analysis.

The results of this study showed that eight weeks of aerobic training with orange juice had no significant effect on the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and fasting blood sugar in overweight middle-aged women. But eight weeks of aerobic training alone and consumption of orange juice alone significantly decreased serum alkaline phosphatase (ALP) levels in overweight middle-aged women (p <0.05).

The results of this study showed that eight weeks of aerobic training with or without orange juice intake had no significant effect on fasting blood glucose and liver enzymes except ALP.
