The Effect of Resistance Training with Black Seed Supplementation on Glycemic Indices in Overweight Women

Introduction:Today, obesity and insulin resistance are recognized as significant factors in the development of metabolic diseases. This study aimed to examine the effects of resistance training combined with black seed consumption on specific glycemic indicators in overweight women. Methods: In this quasi-experimental study, the researchers randomly assigned ۴۸ overweight and obese women to control, training, black seed, and combined training and black seed groups. The two training groups (with and without black seed supplementation) performed a resistance training program at ۵۰–۸۰% of ۱RM, three sessions per week. The black seed group consumed two ۱۰۰۰ mg capsules daily. Tukey’s post-hoc test and one-way ANOVA were used for intergroup data analysis, while intragroup analysis was performed using a paired-sample t-test with SPSS version ۲۶. Results: Compared to their pre-test values and the control group, all three experimental groups showed a reduction in blood glucose, insulin, and the insulin resistance index after eight weeks. A significant decrease was observed in the insulin resistance index (p = ۰.۰۰۰۱), insulin (p = ۰.۰۰۱), and glucose (p = ۰.۰۰۱) levels in the resistance training + black seed group. Furthermore, the training + black seed group exhibited a significant reduction in blood glucose (p = ۰.۰۰۱) and the insulin resistance index (p = ۰.۰۱) compared to the resistance training group alone. Conclusion: Resistance training combined with black seed consumption can improve blood glucose levels, insulin levels, and the insulin resistance index in overweight or obese individuals predisposed to diabetes and cardiovascular diseases.
