A multimodal prehabilitation program enhances functional capacity and body composition before abdominal surgeries for cancer, impacting patient recovery.

• Participants showed improved peak oxygen uptake by 0.6 ml/kg/min and muscle strength gains of up to 18.9 kg in leg press.
• However, these improvements were not sustained postoperatively, with measures often returning to baseline or declining.

Surgeons should consider integrating prehabilitation programs to optimize recovery but remain cautious about long-term benefits.

• Gains varied by tumor type, neoadjuvant therapy, and training compliance, indicating the need for tailored approaches.
