Impact of an 8-Week Aerobic Exercise on BDNF (Brain-Derived Neurotrophic Factor) and Blood Lipids in Obese Women in Twenties

Objectives This study aimed to elucidate the effects of an 8-week aerobic exercise on Brain-Derived Neurotrophic Factor (BDNF) and blood lipids among young obese women in their 20s to provide foundational scientific information for the enhancement of cognitive function and obesity improvement. Methods Participants were young obese women aged 19–25 years old, with a body fat percentage of 29%. They were divided into two groups: an Aerobic Exercise Group (AEG) with nine members and a Control Group (CG) with eight members. The exercise regimen employed a 50–60% Target Heart Rate (THR) intensity and was conducted for eight weeks. The training sessions took place four times a week and comprised a 10-minute warm-up, 50 minutes of aerobic exercise, and a 10-minute cooldown, which totaled 70 minutes per session. Results Increased BDNF and significantly reduced weight, body fat percentage, triglycerides, total cholesterol, and low-density lipoprotein-cholesterol were observed in the aerobic exercise group. There were significant differences in weight, body fat, body fat percentage, and waist circumference before & after training combined excise group and combined excise protein intake group. Conclusions Therefore, aerobic exercise had a positive impact on cognitive functions and was effective in improving obesity in young obese women. Additionally, compound exercise or a combination of compound exercise and protein intake effectively improved body composition.
