Development and Dissemination of Exercise Prescription and Intervention for Cancer Populations

Inclusion Criteria: 1. Aged 18 to 80 years. 2. Cancer Cohorts: Pathologically confirmed diagnosis of AJCC TNM stage I-III, and having completed curative-intent treatment (including surgery ± adjuvant chemotherapy/radiotherapy, etc) for at least 2 months. 3. Cancer cohort must have an Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0-2. 4. Ability to comply with weekly structured exercise training (3-4 professionally supervised sessions per week) and willingness to accept telephone follow-ups or report exercise status via exercise logs/wearable devices. 5. Self-reported failure to meet the following physical activity guidelines within the past 3 months: at least 150 minutes of moderate-intensity aerobic exercise per week OR at least 75 minutes of vigorous-intensity aerobic exercise per week; AND no regular resistance training (≥ 2 sessions per week) within the past 3 months. Exclusion Criteria: 1. Cardiovascular instability: History of acute coronary syndrome (ACS), myocardial infarction (MI), acute exacerbation of heart failure, or hospitalization for heart failure within the past 3 months; unstable angina; uncontrolled arrhythmia; or uncontrolled hypertension (resting blood pressure \> 180/110 mmHg). 2. Hypoxemia: Resting oxygen saturation (SpO2) \< 90%. 3. Metabolic instability: Severe hypoglycemic event or diabetic ketoacidosis (DKA) within the past 3 months. 4. Musculoskeletal or neurological risks: Unstable bone metastasis or bone metastasis with a high risk of fracture; recent major fracture or orthopedic surgery where weight-bearing is not yet permitted; or other severe neuromuscular diseases that compromise the safety of exercise. 5. Hematological risks: Thrombocytopenia (Platelet count \< 50,000/μL), severe anemia (Hemoglobin \[Hb\] \< 8 g/dL), or neutropenia (Absolute Neutrophil Count \[ANC\] \< 1,000/μL). 6. Deemed unsuitable for exercise intervention as determined by clinical assessment from the attending physician or study investigator. 7. Concurrent participation in other formal exercise or weight-loss intervention programs. 8. Inability to comprehend or complete the informed consent form, or inability to comply with the study procedures.
