Summary
This study investigates a 12-week exercise program for frail older adults in Brazil, aiming to improve functional capacity and reduce fall risk. Results are pending, but the intervention shows promise for healthy aging.
Area of Science:
- Gerontology
- Exercise Science
- Public Health
Background:
- Frailty and pre-frailty are common in older adults, increasing risks of decline, falls, hospitalization, and mortality.
- Multicomponent supervised exercise programs effectively improve physical performance and mitigate frailty in older adults.
- Limited evidence exists on Vivifrail-based interventions for frail and pre-frail populations in Brazil.
Purpose of the Study:
- To evaluate a 12-week supervised multicomponent exercise program's effects on functional capacity and fall risk in Brazilian frail and pre-frail older adults.
- To characterize participants at baseline regarding frailty, vulnerability, cognition, mood, physical activity, muscle mass, and fear of falling.
- To assess sociodemographic and clinical factors influencing outcomes in this population.
Main Methods:
- Prospective, single-blind, randomized controlled trial with 1:1 allocation.
- Intervention group: 12-week supervised multicomponent exercise program (Vivifrail model).
- Control group: Health education workshops on healthy aging.
- Primary outcomes: 6-Minute Walk Test (functional capacity) and Timed Up and Go Test (fall risk/mobility).
Main Results:
- Recruitment and baseline assessments planned for July-December 2026 at CONVIVER Community Center, Rio Verde, Goiás, Brazil.
- Target enrollment: 70 participants (35 per group).
- Participant recruitment and data collection were not yet initiated at manuscript submission; final results anticipated by late 2027.
Conclusions:
- This protocol outlines a supervised exercise intervention for frail older adults in a Brazilian community setting.
- The intervention, if effective, could be a feasible, low-cost, and scalable strategy to enhance functional capacity and reduce fall risk.
- Findings will support evidence-based healthy aging initiatives for vulnerable older populations.
