Brief Summary
This study will evaluate the effectiveness of a virtual assistant-guided exercise program to improve adherence in older adults. In a nonrandomized controlled clinical trial, the experimental group will complete a 12-week, home-based program (60-minute sessions, 3 times per week) supported by a virtual assistant (BOT). The control group will comprise community-dwelling older adults already engaged in the municipal program Enguera se saludable, which delivers an in-person exercise program of comparable frequency and duration. The primary outcome is exercise adherence, defined as the proportion of prescribed sessions completed. Secondary outcomes include muscle strength, balance, functional capacity, health-related quality of life, and the user experience and usability of the virtual assistant.
Eligibility Criteria
Inclusion Criteria: * Adults aged 60 years or older. * Community-dwelling individuals capable of participating in an exercise program. * Ability to complete 60-minute exercise sessions, three times per week during the 12-week intervention. * Experimental group (BOT Group): Participants willing to use a smartphone/tablet and interact with the virtual assistant. * Control group (Municipal Exercise Group): Individuals already enrolled in the municipal program Enguera se saludable. * Ability to understand the study procedures and provide written informed consent Exclusion Criteria: * Medical contraindications to physical exercise, as determined by clinical judgment (e.g., uncontrolled cardiovascular, respiratory, or metabolic conditions). * Severe cognitive impairment or neurological conditions that limit the ability to follow instructions or safely perform the exercise program. * Severe mobility limitations preventing participation in structured exercise (e.g., inability to walk independe
