Adapted Physical Activity (APA) Following Hospitalization in Frail Older Adults

Inclusion Criteria: * The study is open to individuals aged 65 and older. * Current diagnosis or recent history of cancer. * Patients currently undergoing treatment (chemotherapy, immunotherapy, targeted therapy) or in follow-up after recent treatment (≤12 months since completion). * Functional capacity compatible with participation in an adapted physical activity program, as determined by clinical assessment. * Recent hospitalization: Patients must have been discharged following a hospital stay. * Frailty: Presence of a significant level of frailty at hospital discharge. Exclusion Criteria: * Short Physical Performance Battery\> 10: Patients considered "robust" are excluded to maximize the relevance of the intervention. * Acute unstable medical condition or contraindication to exercise: Any unstabilized acute condition that makes physical activity dangerous (e.g., acute cardiac complication, ongoing severe infection). Recent major medical events (myocardial infarction, major surgery, bone fracture, or major amputation in the past few weeks) will also be excluded. * Severe chronic conditions incompatible with exercise: Severe progressive diseases that prevent safe exercise, such as severe neuromuscular diseases or advanced organ failure (e.g., end-stage renal failure). * Short-term life-threatening prognosis: Patients in the terminal phase or with a very limited life expectancy (less than 6 months). * Total functional dependence or severe motor impairment: Patients who are…
