The effect of total body resistance training (TRX) and omega-3 supplementation on serum leptin levels and body fat percentage in overweight and obese women
Pro-inflammatory cytokines such as leptin play an important role in the pathogenesis of obesity and metabolic syndrome. Exercise and food supplements are two suitable approaches to prevent the phenomenon of overweight and obesity. This study aimed to investigate the effect of eight weeks of total body resistance training (TRX) and omega-3 supplementation on serum leptin levels and body fat percentage in overweight and obese women.
In this semi-experimental research, 48 overweight and obese women were purposefully selected as a statistical sample and randomly divided into four groups of 12 people: 1) training, 2) supplement, 3) training +supplement, and 4) control. The subjects of the first and third groups performed the exercise training protocol (TRX) for eight weeks (Three sessions per week). Also, the subjects of the second and third groups received two 1000 mg capsules of omega-3 supplement daily, and the first and fourth groups received the same amount of placebo (Oral paraffin). At the beginning and end of the study, measuring body fat percentage using a body composition measuring device and venous blood samples were collected to measure biochemical values. Data were analyzed using one-way analysis of variance, and Tukey's post hoc test at a significance level of less than 0.05.
