ABSTRACT
BACKGROUND: Resistance training benefits patients with sarcopenia. However, trials demonstrating the effectiveness of Tai Chi combined with elastic band training are sparse, and the underlying neurocognitive mechanisms remain unclear.
METHODS: Forty-nine older sarcopenia patients (≥60 years) were recruited and randomly assigned to three groups: the Elastic Band Group (EBG) received elastic band training; the Combined Group (CG) received elastic band training combined with Tai Chi; the Health Education Group (HEG) received weekly health education via WeChat, focusing on sarcopenia-related precautions Muscle function was assessed pre- and post-intervention using grip strength, muscle mass, and Short Physical Performance Battery. Executive inhibitory function was evaluated using the colour-word Stroop task. Functional near-infrared spectroscopy (fNIRS) was used to simultaneously record cerebral hemodynamic changes in the prefrontal cortex (PFC).
RESULTS: After the 12-week intervention, within-group comparisons revealed no significant changes in any outcome measures in the HEG (P > .05). Both the EBG and CG demonstrated significant improvements compared to baseline in grip strength, muscle mass, physical performance, Stroop task reaction time, and PFC oxygenated haemoglobin concentration (P < .05). Additionally, the CG showed a significant increase in Stroop task accuracy (P < .05). Further between-group comparisons indicated that the CG exhibited significantly greater improvements in physical performance, executive inhibitory function, and PFC oxygenated haemoglobin concentration compared to the EBG (P < .05).
CONCLUSIONS: A 12-week Tai Chi combined with elastic band training program improves physical mobility, enhances executive inhibition, and promotes PFC activation in patients with sarcopenia, with superior efficacy compared to elastic band training alone. These findings provide neuroimaging evidence for the synergistic effects of the combined intervention in sarcopenia intervention.
