There is strong observational epidemiologic evidence that physical activity is inversely associated with risk of colon cancer occurrence in both men and women. This association has been found in over 30 observational studies, and appears to be independent of effects of diet, body fat mass, and other potential confounding factors. Prior to large-scale recommendations regarding exercise as a means of preventing colon cancer, however, more information is needed regarding the type of exercise, when it must be initiated, and how much must be done, in order to produce a protective effect. Information on the mechanisms and biological pathways through which exercise might protect the colon will aid in developing the answers to these questions.
This is a randomized controlled trial of a one-year moderate/vigorous exercise intervention vs. delayed- exercise control on various biomarkers of colon cancer risk in persons that have undergone a colonoscopy within the past 36 months.. The trial is designed to establish the effects of the exercise intervention on colorectal cell proliferation and terminal differentiation, and on factors that may lie in the pathway between exercise and proliferation and apoptosis, in colon and rectal epithelium. It will provide data on: 1) the efficacy of a one-year moderate intensity aerobic exercise program in modulating these processes to a pattern considered low risk for colon cancer, and 2) the mechanisms whereby exercise may lower colon cancer risk in humans. To the investigators' knowledge, this will be the first study of its kind.

Arms | Assigned Interventions |
---|---|
1: Experimental
Exercise
|
Behavioral: Exercise
60 minutes/session of aerobic exercise, 6 d/week at 50-50% HHR. All sessions will begin with 10 minutes of stretching and 5 minutes of warm-up, and will end with 5 minutes of cool down.
|
2: No Intervention
Control
|
Behavioral: Delayed Exercise
Participants in the Delayed Exercise Controls Group will have scheduled clinic visits at baseline, 3, 6, 9 and 12 months. After their end-of-the 12 month study assessments, they will be offered the chance to meet with the exercise physiologist individually to learn aerobic exercise techniques.
