effects of integrated exercise on sarcopenia, depression symptoms, and quality of life

Conditions: Dementia; Depressive Symptoms; Quality of Life (QOL); Sarcopenia in Elderly

Summary: the goal of this quasi-experimental (nonrandomized intervention) study is to investigate the effects of an integrated exercise intervention on sarcopenia, depression symptoms, and quality of life in community-dwelling older adults with dementia. the main questions it aims to answer are: 1. does the integrated exercise intervention improve muscle mass and strength in older adults with dementia? 2. how does the intervention affect the participants' depression symptoms? 3. what changes occur in the quality of life of participants following the exercise program? in this study, participants will: 1. be divided into two groups: an integrated exercise group and a control group. 2. the intervention group will participate in a 12-week integrated exercise program consisting of strength training, aerobic exercise, stretching, and balance training, performed for 50 minutes at least three times a week. 3. assessments will be conducted before the intervention and after 12 weeks, including body composition analysis, grip strength measurement, physical function tests, and structured questionnaires evaluating demographics, depression symptoms, and quality of life. this study aims to determine the effectiveness of integrated exercise in addressing sarcopenia, alleviating depression symptoms, and enhancing the quality of life among older adults with dementia. the findings may provide valuable insights for developing community-based exercise interventions for this population.

this study explored the effects of an integrated exercise intervention on sarcopenia, depressive symptoms, and quality of life in community-dwelling older adults diagnosed with dementia. sarcopenia, characterized by the loss of muscle mass and strength associated with aging, poses significant risks, including frailty, disability, and reduced quality of life, particularly among older adults. given the rising prevalence of dementia globally, addressing the effects of sarcopenia in this population was crucial. the proposed intervention involved a carefully structured exercise program tailored to enhance physical function and emotional health, incorporating elements of strength training, aerobic exercise, stretching, and balance activities. participants were recruited from outpatient neurological/dementia clinics and community centers in taiwan, targeting individuals aged 65 and above. selection was based on established eligibility criteria. those assigned to the integrated exercise group engaged in a 12-week program, attending exercise sessions lasting 50 minutes at least three times per week. meanwhile, the control group continued with their regular daily activities without any structured exercise regimen. to assess the intervention's effectiveness, various outcome measures were utilized. these included evaluations of body composition, grip strength, and physical function, along with structured questionnaires to assess depressive symptoms and overall quality of life. assessments took place at baseline and at the conclusion of the 12-week program, allowing for a comparison of pre- and post-intervention outcomes. the findings from this study provided valuable insights into the role of structured physical activity in mitigating the effects of sarcopenia and enhancing mental health among older adults living with dementia. ultimately, the results will inform the development of effective, community-based strategies aimed at improving the overall well-being of this vulnerable population.
