Detailed Description:

METHODS Research Questions: Research Question 1 (primary). Is a virtually-delivered, peer matching exercise intervention supported by qualified exercise professionals (QEP) feasible for older adult cancer survivors? Research Question 2. Do older adult cancer survivors who participate in a virtually-delivered peer matching exercise intervention with QEP support have improved levels of social support compared to those matched with a peer only? Research Question 3. Do older adult cancer survivors who participate in a virtually-delivered peer matching exercise intervention with QEP support have improved levels of physical activity behaviour, health-related quality of life and physical functioning compared to those who are matched with a peer only? Study Design: This is a two-arm pilot randomized controlled trial with blinded outcome assessment. The protocol and study methods adhere to the CONSORT extension for randomized pilot trials. The Hamilton Integrated Research Ethics Board will approve this study. Dyads will be randomized (1:1) to the Intervention (AgeMatchPLUS) or control (AgeMatch) groups prior to baseline assessment. Group allocation will be centrally randomized using a web platform (https://www.randomizer.org/) by a graduate student external to the research team. A Research Assistant will assign group allocation in the order participants complete an initial demographics questionnaire and are matched with a peer for the study. Intervention: Peer Matching. A Research Assistant will match all participants into dyads based on evidence-informed criteria. To be matched, females must be in the same time zone and diagnosed with the same type of cancer. Matched peers will be introduced to each other by a Research Assistant via zoom after baseline data collection. All participants will be given a peer support guide that provides tips for supporting their exercise partner, an infographic on exercise guidelines for older cancer survivors and a Fitbit Inspire 2©. Partners will independently communicate and support each other around exercise for the duration of the study. Intervention Group (AgeMatchPLUS). This group will have dyads participate in weekly virtual sessions with a QEP for 10 weeks. Each session will last up to 1 hour. The QEP (i.e., registered kinesiologist) will provide a tailored exercise program, focusing on aerobic activity with both participants in the dyad based on personal circumstances, cancer-related characteristics, side effects, current fitness level, and personal preferences. Overall, content discussed at the sessions will include a review of the exercise program, barriers to exercise participation, achievement of goals, and adverse events. For four weeks following the 10-week intervention, the QEP will be available for consultation (labelled "tapering" period) as needed by participants in this group. This tapering period is important to understand strategies to successfully taper older adults from an exercise trial. Also, during the tapering period, participants in this group will receive two supportive emails from the QEP encouraging ongoing maintenance of exercise and social support. Control Condition (AgeMatch): Dyads in this group will independently communicate and support each other around exercise for 10 weeks. They will not have contact with the QEP during the intervention or tapering period and will structure their communication (mode and frequency) with their matched peer.}}
