Physiological regulation of moderate-intensity exercise in improving the biomarkers visfatin and myonectin as a modulator of increasing metabolic performance in obese.

Abstract

Objectives: A well-structured, regular, and programmed physical exercise regimen is believed to be an effective physiological modulator for preventing the dysfunction of myonectin and visfatin secretion. Therefore, this study aims to analyze the physiological regulation of moderate-intensity programmed exercise in improving myonectin and visfatin biomarkers in obese women.

Methods: The study involved 30 physically healthy obese women, nonathletes, selected based on predetermined criteria, who voluntarily agreed to participate. They were then divided into two groups: a control group (CRT; n=15) and a programmed exercise group (ART; n=15). The exercise program lasted for 8 weeks, with a frequency of 5 times per week at moderate intensity. Metabolic performance was analyzed using the myonectin and visfatin biomarkers with the Sandwich-ELISA method. Data analysis was conducted using parametric paired sample t-tests and independent sample t-tests at a 5 % significance level.

Results: The study results showed a significant increase in myonectin secretion and a decrease in visfatin secretion (p≤0.05) after 8 weeks of programmed exercise, demonstrated by an increase in myonectin of 97.85 pg/mL and a decrease in visfatin of 0.05 ng/mL. Conversely, in the control group, myonectin decreased by 3.04 pg/mL, and visfatin increased by 0.03 ng/mL.

Conclusions: These findings confirm that an 8-week programmed exercise regimen can improve the secretion of myonectin and visfatin biomarkers, thereby enhancing metabolic performance in obese women. Thus, myonectin and visfatin biomarkers induced by programmed exercise serve as modulators for enhancing metabolic performance in obese women.
