Brief summary
This 12-week, exercise study will assess the feasibility of a home-based high-intensity interval training (HIIT) program among colorectal cancer survivors and explore the impact of home-based HIIT compared to a standard home-based moderate-intensity continuous aerobic exercise program on physical outcomes linked with survival from colorectal cancer and surrogate blood markers of colorectal cancer recurrence. HIIT is a type of aerobic exercise that includes short bursts (i.e. 1-4 minutes) of vigorous exercise followed by longer periods of moderate to lower intensity exercise (i.e. 1-10 minutes). Participants in this study will be randomly assigned into a personalized home based exercise program - either high-intensity interval training (HIIT) or moderate-intensity continuous aerobic exercise (MICE). This pilot study will provide us with preliminary evidence for a larger trial aimed to compare the effectiveness of these two different types of home-based exercise programs on physical outcomes linked with survival, quality of life, and surrogate blood markers of colorectal cancer recurrence.
Interventions
BEHAVIORALHome-based high-intensity interval training
Participants will be instructed to complete four, high-intensity interval training workouts per week at home, for the duration of the 12-week trial. Participants will be provided with detailed instructions on how to complete each workout.
BEHAVIORALHome-based moderate-intensity continuous exercise
Participants will be instructed to complete five, moderate-intensity continuous exercise workouts per week at home, for the duration of the 12-week trial. Participants will be provided with detailed instructions on how to complete each workout.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of home-based high-intensity interval training among colorectal cancer survivors | 12 weeks | Feasibility will be assessed by adherence to the home-based high-intensity interval training protocol, which is defined at the participant level as completing ≥70% of workouts consistent with the exercise prescription. The intervention will be considered feasible if ≥75% of participants meet or exceed the 70% criterion. |
