Impact of Physical Activity Participation on Social Participation and Life Satisfaction in Elderly People with Sarcopenia and its Psychological Adaptation Mechanism

Abstract

This article studied the benefits of participating in physical activities for the elderly with sarcopenia, especially in terms of enhancing their sense of social participation, life satisfaction and psychological adaptation. This study not only has important theoretical significance for improving the overall health level of the elderly and promoting social integration, but also provides an empirical basis for the formulation of effective health intervention policies for the elderly. Through the screening test for myopenia for the elderly over the age of 65 in urban area A as the subject of the survey, 60 patients were selected for the study, and they were randomly divided into experimental groups and reference groups. After many weeks of physical activity intervention, the experimental group used tools such as skeletal muscle mass index, self-test health assessment scale, and elderly depression scale for quantitative analysis. The collected data is processed and analyzed through statistical software, and descriptive statistical analysis is used to describe the basic characteristics of the sample. In addition, this study also uses advanced statistical methods such as structural equation models to further reveal the complex relationships between variables. The experimental results show that physical activity significantly improves the sense of social participation of the elderly with myotonia, especially in terms of personal recreational activities and outdoor autonomous participation (P<0.01), both of which have very significant differences. The scores of the elderly in the experimental group on the comprehensive quality of life scale significantly improved after the experiment, especially in terms of psychological function and material life (P<0.01), with significant differences compared to the reference group. Physical activities also promoted the psychological adaptation mechanism of the elderly, helping them actively cope with life challenges and effectively reducing depressive emotions. The analysis through the Geriatric Depression Scale revealed a significant difference between the experimental and reference groups after the physical activity intervention (P<0.05). Therefore, elderly people with muscular dystrophy should be encouraged and supported to actively participate in physical activities to comprehensively improve their physical and mental health and quality of life.
