Prehabilitation exercise programs can reduce complications and shorten hospital stays for elderly patients undergoing abdominal or cardiac surgery. This approach enhances functional capacity, improving recovery and quality of life post-surgery.

Area of Science:

  • Geriatric Medicine
  • Sports Medicine
  • Surgical Outcomes

Background:

  • Limited research exists on prehabilitation (exercise before surgery) compared to rehabilitation (exercise after surgery).
  • Prehabilitation aims to improve functional exercise capacity in elderly patients to reduce postoperative morbidity and speed recovery.

Purpose of the Study:

  • To evaluate the effectiveness of prehabilitation programs in enhancing functional exercise capacity in elderly patients.
  • To determine if prehabilitation can minimize postoperative complications and accelerate recovery.

Main Methods:

  • A 3-month progressive exercise program including aerobic training (45-65% maximal heart rate reserve, %HRR) with high-intensity interval training (approx. 90% HRR) four times weekly.
  • Strength training twice weekly, targeting large muscle groups with 80% of one-repetition maximum intensity.

  • Nutritional guidelines: 140g carbohydrates 3 hours pre-exercise and 200 kcal protein-carbohydrate mix within 30 minutes post-exercise.

    • Main Results:

    • Prehabilitation before orthopaedic surgery showed no significant improvement in quality of life or recovery.
    • For abdominal or cardiac surgery patients (n=275), prehabilitation led to fewer postoperative complications.
    • Prehabilitation resulted in shorter hospital stays, improved quality of life, and reduced functional decline compared to sedentary controls.

    Conclusions:

    • A structured 3-month prehabilitation program combining aerobic, high-intensity interval, and strength training is recommended for cardiovascular improvement.
    • Specific pre-exercise and post-exercise nutritional strategies are advised to optimize glycogen stores and muscle hypertrophy.
    • Prehabilitation shows promise for improving surgical outcomes in specific patient populations, particularly for abdominal and cardiac procedures.
