deconditioned
Deconditioning is a decline in physical function that results from prolonged inactivity, illness, or immobilization. The term describes a state in which muscles lose strength and endurance, cardiovascular efficiency decreases, and overall energy levels are reduced compared with prior baseline. It is common after hospitalization, injury, surgery, or chronic diseases that limit activity, and it tends to occur more rapidly in older adults due to age-related changes in muscle mass and vascular function.
Causes and mechanisms include extended bed rest, sedentary behavior, poor nutrition, dehydration, and systemic illness. Physiological
Signs and functional impact of deconditioning may include easily fatigued individuals, noticeable weakness, slower walking speed,
Management focuses on graded reconditioning. A tailored program combines resistance training to rebuild muscle strength with
Prevention emphasizes early mobilization during illness or hospitalization, regular physical activity, and attention to nutrition. For
