Physical activity guidelines for older people: knowledge gaps and future directions

Area of Science:

• Gerontology
• Exercise Physiology
• Public Health

Background:

• Physical function (aerobic capacity, gait speed, muscle strength) is a key biomarker for healthy aging, predicting adverse health outcomes.
• Physical exercise is a proven therapeutic strategy to prevent disease and functional decline.
• Supervised exercise in hospitalized older adults (≥75 years) effectively prevents functional and cognitive decline.

Purpose of the Study:

• To explore tailored physical activity guidelines for maximizing exercise benefits on function.
• To advocate for the integration of exercise into primary and geriatric medical practice.
• To emphasize the ethical imperative of prescribing physical exercise for frail older adults.

Main Methods:

• Review of current evidence on exercise benefits for frail older adults.
• Analysis of barriers to exercise integration in medical practice.
• Recommendations for healthcare system improvements.

Main Results:

• Few studies have investigated tailored physical activity guidelines.
• Exercise is underrepresented in medical training and practice.
• Physical trainers should be integrated into healthcare systems.

Conclusions:

• Prescribing physical exercise for frail older adults is an ethical necessity.
• Efficient implementation of evidence-based exercise programs is vital for healthy aging.
• Healthcare systems must adapt to better support exercise interventions for older adults.
