Comparative Analysis of Physical Function and Adipomyokines According to Exercise Type in Obese Elderly Women

PURPOSE The purpose of this study was to examine the effects of different types of exercise on physical function and adipomyokine levels in obese older women. METHODS A total of 45 obese women aged 65 years or older were randomly assigned to one of three groups: an aerobic exercise group (AEG), a re...

description PURPOSE The purpose of this study was to examine the effects of different types of exercise on physical function and adipomyokine levels in obese older women. METHODS A total of 45 obese women aged 65 years or older were randomly assigned to one of three groups: an aerobic exercise group (AEG), a resistance exercise group (REG), and a control group (CG), with 15 participants in each. The AEG and REG participated in an 8-week intervention consisting of three 60-minute exercise sessions per week, while the CG maintained their usual daily activities. Physical function and serum adipomyokine levels (Irisin and FGF-21) were assessed before and after the intervention. RESULTS Both the AEG and REG showed significant reductions in body mass and body fat (p<.001). Muscle mass significantly increased in the REG (p<.01). Skeletal Muscle Index (SMI) increased in the AEG (p<.05) and REG (p<.01), and BMI significantly decreased in both groups (p<.001). Waist circumference decreased in the AEG (p<.01) and REG (p<.001), and hip circumference decreased in both groups (p<.01). Irisin levels significantly increased in the AEG (p<.01) and REG (p<.05), as did FGF-21 levels (p<.01 in both). Grip strength improved significantly in the REG (p<.01), and chair stand performance improved in the AEG (p<.01) and REG (p<.001). Arm curl performance increased in the AEG (p<.01) and REG (p<.001). The 2-minute step test showed significant improvements in both the AEG and REG (p<.001). The 244-cm timed up-and-go test times significantly decreased in the AEG and REG (p<.001), indicating improved agility. CONCLUSIONS Aerobic and resistance exercise interventions in obese older women with sarcopenic obesity led to significant improvements in physical function and increases in adipomyokines (Irisin and FGF-21), compared to no exercise. These findings suggest that both aerobic and resistance training are effective and necessary components of exercise programs for this population, regardless of modality.
