Abstract

Obesity is closely related to a decrease in brain-derived neurotrophic factor (BDNF) expression, which will pose a risk for metabolic disorders. Therefore, this study aims to prove the effect of moderate-intensity aerobic exercise on increasing BDNF expression in obese women. A total of sixteen obese women were selected based on predetermined criteria and were divided into 2 groups, namely the aerobic exercise group (AE) and the control group (CN). Aerobic exercise was carried out by running on a treadmill at moderate intensity (60-70 HRmax) for 40 minutes/session with a frequency of 5x/week for 2 weeks. Blood samples were taken twice before and after exercise intervention to see BDNF expression using the Enzyme-Linked Immunosorbent Assay (ELISA-kit) method. The results of the analysis showed differences in increase between the control group (1816.66 ± 689.48 vs. 1822.86 ± 467.87 pg/mL; p = 0.974) and the intervention group (2173.81 ± 705.89 vs. 3635.01 ± 699.71 pg/mL; p = 0.013). This shows that moderate-intensity aerobic exercise carried out for 2 weeks has proven effective in increasing BDNF expression in obese women.

Abstract

Obesity is associated with increased betatrophin levels, which can lead to fat metabolism disorders. Increased levels of betatrophin may inhibit the performance of the lipoprotein lipase (LPL) enzyme, making it difficult for triglycerides (TG) in the blood to be converted into energy and causing excessive fat accumulation in adipose tissue. Physical exercise has been reported to increase energy expenditure in obesity. This study aims to determine changes in betatrophin in obese women after moderate-intensity aerobic exercise. A total of twenty obese women aged 20-30 years took part in the study. The participants were administered into two groups: control (K1) and moderate-intensity aerobic exercise (K2). Moderate-intensity aerobic exercise (60-70% HRmax) was performed five times a week for two weeks. Pretest and posttest betatrophin levels were measured using the Enzyme-Linked Immunosorbent Assay (ELISA) Kit method. Data were analyzed using a paired samples t-test with a significance level of p ≤ 0.05. The results showed the average pretest and posttest betatrophin levels in K1 (0.44±0.14 vs 0.44±0.13 ng/mL; p=0.894), and K2 (0.41±0.05 vs 0.31±0.03 ng/mL; p=0.000). According to the study's findings, moderate-intensity aerobic exercise (60-70% HRmax) performed five times per week for two weeks positively impacted alterations in betatrophin levels in obese women.
