AB  - Physical activity (PA) after a colorectal cancer (CRC) diagnosis can improve physical function and quality of life and is associated with decreased mortality rates and longer disease-free survival. The accelerated use of videoconference technology during and following the COVID-19 pandemic offers an opportunity to explore the potential of a virtually supervised intervention to help survivors of CRC increase PA. A two-arm single blind pilot randomized controlled trial of individuals who had completed treatment for CRC within the previous five-years (NCT03781154, 12/19/2018). The 12-week intervention consisted of circuit-based, combined aerobic and resistance exercise, twice per week for approximately one-hour per session, and five social cognitive theory-based PA behavior change discussion sessions. All intervention components were delivered in real-time via Zoom. Feasibility and acceptability were assessed, and the effects of the intervention were explored for the outcomes of PA (activPAL™ accelerometers and self-report), social cognitive theory constructs (barriers self-efficacy and outcome expectations), and physical fitness (submaximal aerobic capacity, upper and lower body muscular strength and endurance). Twenty-nine eligible individuals (55.2% women, Mean = 61 ± 11 years old, Mean = 22.0 ± 15.1 months since diagnosis) were randomized to the videoconference PA intervention (n = 15) or a PA education control (n = 14). A total of N = 25 completed the study for a retention rate of 86.7% in the intervention arm and 85.7% in the control. Adherence to intervention components was >86%. The intervention was highly acceptable with ≥90% responding “yes” or “definitely yes” that they enjoyed participating. Trends suggested that intervention participants had greater improvements in accelerometer measured steps per day, daily minutes of light PA, sedentary time, and aerobic fitness. There was no change in social cognitive theory constructs, and muscular strength and endurance improved in both the intervention and control. A 12-week videoconference PA intervention was feasible and acceptable among survivors of CRC, and the greatest magnitude of difference for intervention effects was observed for light PA and sedentary time. A fully powered trial is needed to determine efficacy of the intervention for increasing PA and physical functioning.
