The Effects of 8-Weeks Resistance Exercise on Body Composition, Muscle Strength and Dementia Related Factors in Elderly Women with Sarcopenic Obesity

The purpose of this study was to determine the effects of exercise on improving sarcopenic obesity and preventing dementia by analyzing changes in body composition, muscle strength, and dementia-related factors after an 8-week resistance training program in sarcopenic obese elderly women. A total of 22 elderly women aged 65 years or older who met the criteria for sarcopenia and obesity were randomly assigned to a resistance training group(n=11) and a control group(n=11), and body composition, muscle strength, and blood dementia-related factors were measured and analyzed before and after 8 weeks of resistance training using a weight machine. The results showed a significant decrease in weight, body fat(%), waist circumference, and hip circumference, and a significant increase in grip strength, hip flexors, knee flexors and extensors, and elbow flexors. BDNF and HDL levels also significantly increased. In conclusion, resistance training was effective in improving neurotrophic factors, lipid metabolism, and muscle strength, suggesting that it may be a good intervention for the prevention of sarcopenic obesity and dementia in elderly women.
