The effect of aerobic exercise and isoflavone soy supplementation (Glycine soja) on changes in hemoglobin A1C and fasting blood sugar in type 2 diabetic patients

Exercise along with sutible diet and medication are the basic methods of treating type 2 diabetes. The present study aimed to investigate the effect of aerobic exercise and isoflavone soy supplementation (Glycine soja) on changes in hemoglobin A1C and fasting blood sugar in type 2 diabetic patients.

In this semi-experimental study, 56 men and women with type 2 diabetes referred to Zahedan Dietetic Clinic with a range of 25-35 years through targeted sampling and randomly in four groups (of 7 females and 7 males) were divided into aerobic supplementation, aerobic exercise, supplementation, and diet. The study lasted 12 weeks and aerobic exercise. One Isoflavone soy tablet (50 mg) was given daily. The diet of all groups was 5% lower calorie restriction and 10% daily energy increase. Blood sampling was performed 24 hours before and 48 hours after the intervention. SPSS-22 software and dependent T-statistical methods and one-way analysis of variance at a significant level (P<0.05) were used to analyze the data.

In all four groups, FBS and HBA1C factor of men and women decreased significantly (P<0.05), but in the FBS factor men compared to the intergroup, all four groups had a significant difference (P <0.05).

Aerobic exercise and soy isoflavone supplementation (50 mg daily) improve the risk factors for type 2 diabetes. Therefore, exercise and consumption of soy isoflavone supplement can be used as an alternative to drug therapy in the recovery of patients with type 2 diabetes, but this issue needs more and more accurate research.
