The Claim

Trimodal prehabilitation (nutritional optimization, aerobic training, psychological preparation) administered for 3–6 weeks significantly increases six-minute walk distance by 121% and incentive spirometry forced vital capacity by 114% in adults undergoing elective colorectal cancer surgery, but these improvements are not maintained at 8 weeks postoperatively.

In plain English

Adults preparing for colorectal cancer surgery who complete 3 to 6 weeks of combined nutrition, exercise, and psychological training walk 121% farther in six minutes and breathe 114% more air during spirometry tests before surgery, but these improvements disappear by eight weeks after surgery.

See the scientific wording

Trimodal prehabilitation (nutritional optimization, aerobic training, psychological preparation) for 3–6 weeks significantly improves preoperative functional capacity, increasing six-minute walk distance by 121% and incentive spirometry forced vital capacity by 114% in adults undergoing elective colorectal cancer surgery, but these gains are not sustained at 8 weeks postoperatively.

Why this might work

Exercise strengthens muscles and improves how they use oxygen, while better nutrition gives them the fuel to repair and grow. This makes the muscles used for walking and breathing work more efficiently, so a person can walk farther and take deeper breaths. After surgery, the body loses this advantage because it stops getting the exercise and nutrition that maintained it.

  1. Study: Identifying Patients with Colorectal Cancer Likely to Benefit from a Trimodal Prehabilitation Prior to Surgery

    Before surgery, patients who did exercise, ate better, and got mental support could walk 121% farther and breathe 114% better — but by eight weeks after surgery, those improvements were gone. The study confirms this exactly.
