Benefits of Strength Training in Informal Caregivers of Patients With Alzheimer's Disease

Informal caregivers of people with Alzheimer's disease experience high physical and psychological burden, increasing their risk of frailty, anxiety, and caregiver burnout. This randomized controlled trial aims to evaluate the effectiveness of a combined strength training and progressive muscle relaxation program compared with progressive muscle relaxation alone. The intervention will last 10 weeks, with assessments conducted at baseline, post-intervention, and at a 3-month follow-up. Primary outcomes include frailty, anxiety, and caregiver burden.

Inclusion Criteria: * Adults aged 18 years or older * Informal caregivers of a person with Alzheimer's disease * Providing regular care for at least 10 hours per week * Ability to attend intervention sessions * Ability to understand and follow instructions * Provision of written informed consent Exclusion Criteria: * Acute illness or medical conditions contraindicating participation in strength exercise * Participation in structured exercise programs that may interfere with study outcomes * Severe or uncontrolled psychiatric disorders * Physical limitations preventing completion of functional assessments
