Abstract:
The effects of different exercise interventions on patients with sarcopenia based on multislice spiral CT imaging are investigated.92 patients aged 60~75 years with sarcopenia were recruited and randomly divided into an aerobic training(AT) group, a resistance training(RT) group and a blank control(CG) group.Both of AT and RT groups implemented the exercise prescription intervention while CG group received usual care management. The intervention period was 20 weeks.One CT scan of the upper abdomen was performed on the patient one week before and one week after the intervention to measure L3 SMA、L3 SMD as well as area and density of inter-muscular fat, and then to compare the differences in imaging indices between the three study groups before and after the intervention.The results show that exercise can effectively delay the development of sarcopenia, RT have a better effect than AT. RT can effectively improve or even reverse age-related progressive decline in skeletal muscle mass. Both AT and RT help to prevent age-related inter-muscular fat accumulation in older people, but cannot be reversed.
