Effect of submaximal and maximal training on serum levels of asprosin, metabolic parameters and body composition in overweight and obese women.

Objectives: This study evaluated the effects of maximal and submaximal exercise training on serum levels of Asprosin, insulin resistance, and body composition in overweight and obese women.

Methods: 30 overweight/obese women voluntarily participated in the study and were then randomly divided into control, submaximal, and maximal groups. A treadmill high-intensity exercise protocol was applied to MG non-consecutive three days a week for 8 weeks, in four 4-min intervals with an intensity of 70 to 95% of maximum heart rate (HRmax) with 3-min active recovery intervals. SMG performed a moderate-intensity exercise protocol of approximately 25 to 35 min at the treadmill at 50-70% of HRmax non-consecutive days three days per week for 8 weeks. The CG continued their daily routine activities. Anthropometric and body composition measurements such as body weight, height, BMI, and waist-hip ratio (WHR) were performed before and after the 8-week training period. Fasting blood glucose (FGB), insulin, insulin resistance (HOMA-IR), and serum asprosin levels were also measured.

Results: Post-training, there were significant main effects of time and a group-by-time interaction for all body composition and performance variables (p < 0.001). Post hoc analysis revealed that body mass, BMI, WHR, FBG, insulin, HOMA-IR, and serum asprosin were significantly reduced after 8 8-week training program.

Conclusions: The present study showed that maximal and submaximal exercise protocols effectively improved body composition, insulin sensitivity, resistance, and reduced asprosin level. It has been concluded that these effects are more pronounced, especially after maximal exercise protocols.
