[PURPOSE] This study set out to apply remote exercise program to elderly women with sarcopenic obesity and investigate its effects on their body composition and physical function. [METHODS] The subjects include 18 elderly women (80.66±6.46 years old) with sarcopenic obesity whose SMI (Skeletal Muscle Index) was 25.1% or lower based on ASM (Appendicular Skeletal Muscle Mass) and percent fat was 30% or upper according to the dual-energy X-ray absorptiometry results. The exercise group (n=9) carried out remote exercise, which consisted of resistance exercise for 30~50 minutes a day three times per week for 12 weeks. The control group (n=9) maintained the normal life style throughout experiment without special treatments. The investigator measured the factors related to body composition and physical function before and after the experiment and analyzed data using repeated measures of two-way ANOVA with the statistical significance level set at α=.05. [RESULTS] There were significant interactive effects between the time of measurement and groups in body fat percentage (p=.019), upper limb muscle mass (p=.041), SMI (p<.001), and arm curls (p=.002). [CONCLUSIONS] The 12-week remote exercise program seems to have positive influences on the body fat, upper limb muscle mass, SMI, and arm curls for elderly women with sarcopenic obesity. For future research, it would be applied to broader participants who need ICT (Information & Communication Technology) based remote exercise, including the disabled and young or middle-aged adults, suggesting a new research modality in kinesiology.
