Practical guidelines for exercise prescription in different clinical populations

: Exercise training represents a cornerstone therapeutic intervention for managing chronic health conditions, yet its practical implementation in clinical settings remains suboptimal due to challenges in individualization and safety considerations across diverse patient populations. This narrative review provides practical guidelines for exercise prescription in outpatients with chronic conditions, grounded in recent international recommendations and current scientific evidence. Practical considerations for exercise prescription are addressed across various chronic conditions including cardiovascular disease, heart failure, diabetes, and cancer, with particular emphasis on pre-exercise evaluation in patients with hypertension-related organ damage, decompensated heart failure, and frailty. Exercise prescription should be personalized and adapted to individual health status through gradual and progressive incremental physical activity programs designed to optimize health outcomes while minimizing risks. Social, psychological, environmental factors, and technology integration represent important determinants of adherence that warrant systematic consideration. The successful translation of exercise prescriptions into effective training programs requires dedicated clinical facilities staffed by specialized professionals who can bridge the gap between prescription and implementation.
