Abstract

Introduction: Regular sports exercises and the use of food strategies are always considered as low-risk and healthy approaches for coping and treatment of obesity. In this regard, the present study was performed with aim to determine the effect of concurrent training with Flaxseed supplementation on body mass index, glucose, insulin and insulin resistance in overweight girls.
Methods: This clinical trial was performed on 36 overweight women in Tabriz University in 2017. The subjects were randomly divided into four groups (n=9 in each group), including training along with supplementation, concurrent training, supplementation Flaxseed and control. Concurrent training included aerobic exercises with an intensity of 65% of heart rate and resistance training with intensity of 60% 1RM. The subjects used the powdered seed one hour before food, at three meals and dissolved in 250 mg of water, during four weeks of supplementation course. Insulin value was measured using an ELISA kit, fasting glucose level by autoanalyzer, and insulin resistance by homoeostasis model (HOMA). Data was analyzed by SPSS software (version 22) and ANOVA, repeated measurements variance analysis, and bonferroni post hoc. P Results: In concurrent training group, after four weeks, there was a significant decrease in WHR (P=0.015), and supplementation of flax seed alone caused a significant reduction in weight (P=0.008), fat percentage (P=0.041), WHR (P=0.015). Meanwhile, interventions could not affect insulin (P=0.511), insulin resistance (P=0.549), and glucose (P = 0.600).
Conclusion: Four weeks of concurrent training and Flaxseed supplementation had no significant effects on glucose and insulin-related indices, and body composition. The use of such independent variables requires more research.
