Abstract: Objective To investigate the effects on muscle function and fall efficacy in the elderly sarcopenia patients with the high risk of falling by sitting exercise therapy. Methods From August 2017 to January 2020, 45 elderly patients with sarcopenia were intervened with resistance and aerobic exercise for 4 months. The score of Short Physical Performance Battery(SPPB), grip strength, muscle mass, fall efficacy and fall risk were evaluated and compared before and after the intervention. Results Compared with before intervention, there were no significant difference in grip strength and left arm muscle mass (P>0.05); The scores of SPPB, right arm muscle mass, both leg muscle mass, fall efficacy and fall risk were significantly improved (P<0.05). Conclusions Sitting exercise intervention prescription can significantly reduce the risk of falls and improve some muscle function of the elderly sarcopenia patients with high fall risk.
