Supervised Versus Non-supervised Exercise on Adherence and Functional Outcomes in Colorectal Patients

Effects of a Supervised Versus Non-supervised Exercise Program on Adherence and Functional Outcomes in Colorectal Cancer Patients

Investigation into prehabilitation by increasing the supervision of exercise in patients undergoing colorectal resection for cancer and comparing with patients involved in a rehabilitation group receiving exercise after surgery.

The aims of this research project are the following:

To determine to what extent a structured multimodal prehabilitation regimen, which includes aerobic and resistance exercise, nutritional supplementation and psychological coping strategies, initiated before surgery, and continued while in hospital and after surgery, optimizes the recovery of functional walking capacity following colorectal resection for cancer.

To understand which measures of immediate surgical recovery are sensitive to prehabilitation interventions and predict change in later outcome measures.

Inclusion Criteria:

• referred electively for resection of malignant, non metastasized, colorectal lesions.
• French or English speaking

Exclusion Criteria:

• ASA class 4-5
• co-morbid medical, physical and mental conditions (e.g. dementia, disabling orthopedic and neuromuscular disease, psychosis)
• cardiac abnormalities
• severe end-organ disease such as cardiac failure (New York Heart Association classes I-IV), COPD, renal failure (creatinine > 1.5mg/dl, and hepatic failure ALT and AST > 50% over the normal range)
• Sepsis
• Morbid obesity (BMI > 40)
• Anemia (hematocrit < 30%, haemoglobin < 10g/dl, albumin < 25mg/dl).
