This study aimed to investigate the interactive effect of aloe vera intake and eight weeks’ aerobic exercise on serum BDNF, glucose, and insulin levels in women with type 2 diabetes. In this experimental study, 32 women with type 2 diabetes were selected and randomly divided into four groups of control, supplement, exercise, exercise + supplement. The exercise program was performed 3 sessions per week for 8 weeks (40 min of exercise with 50-60% of heart rate reserve in the first four weeks and 60 min of exercise with 60-80% of heart rate reserve in the second four weeks). The supplement taking groups received 400 mg/kg of oral aloe Vera 3 days per week for 8 weeks. The data were analyzed using analysis of covariance (ANCOVA). A significant increase was observed in BDNF levels, insulin sensitivity of patients in the supplement, exercise, and exercise + supplement groups (p=0.001). The glucose and insulin levels, insulin resistance, BMI, and body fat percentage significantly decreased in the supplement, exercise, and exercise + supplement groups (p=0.001). It seems aloe Vera intake and aerobic exercise to have protective effects against development of type 2 diabetes complications in women.

What is already known on this subject?

Although the amount of BDNF (Key factor in brain-muscle cross talk) measures has increased with exercise training, to date, it remains an open question that BDNF change with aerobic exercise and aloe vera intake in women with type 2 diabetes.


What this study adds?

BDNF is produced and secreted by human skeletal muscles and other organs. BDNF has antidiabetic effect and associate with circulating anti-inflammatory cytokines in T2DM. This study show increase BDNF with aerobic exercise and aloe Vera intake in T2DM.
