Abstract

Sarcopenic obesity (SO) is defined as a combination of obesity and sarcopenia, leading to serious health consequences. However, a lack of suitable animal models has hampered research into this disorder. 12-month-old Sprague-Dawley rats were given a high fat content (HFD, SO group) or standard diet (DC groups) for 28 weeks (until 20 months of age). In addition, 2-month-old rats were fed a standard diet as an age control (YC group) until they reached 10 months of age. At the end of the intervention, quadriceps development in the rats was monitored using magnetic resonance examinations and MR spectroscopy. Age-related changes in muscle mass and strength, histopathology, HFD-induced adiposity, and metabolic disturbances were compared between the three groups. Comparing with DC group, rats of SO (20 months, and fed by high-fat diet) exhibited a more prominent loss of muscle mass and strength, a more pronounced decline in myofibre number, IFM, increase in myocyte apoptosis accompanied with increased visceral fat, remarkable glycolipid metabolic disorders, and insulin resistance. However, DC group rats (20 months with standard diet) only showed a decline in quadriceps cross-sectional area/body weight, forelimb grip strength, myofibre cross-sectional area and number, and intermyofibrillar mitochondria number (IFM), increased myocyte apoptosis, without significant metabolic disorder compared with YC group rats. After verifying, SO animal model was successfully set up by HFD induced obesity concomitant with aging-related sarcopenia.
