A Randomized Control Trial - Zoomers for the Capital Region: A Peer-Led Exercise Program for Aging Adults

This study is a randomized control trial where subjects will be randomly assigned to a control or an intervention group. Participants will be recruited through general advertisements (e.g. radio, newspaper, posters), in Fredericton and surrounding areas. These participants will be volunteers, and no compensation will be provided besides having access to a free exercise program in their community. Eligibility will be determined by the research staff prior to the baseline assessment day.Eligible participants will be evaluated at an initial day of testing at either a Horizon CommunityHealth Centre or at the University of New Brunswick in the Cardiometabolic Exercise and Lifestyle Laboratory (CELLab). This first visit will involve the confirmation of eligibility, reading and signing a consent form, and the administration of the measurements discussed previously. All research staff will have received the appropriate training to deliver these fitness assessments, finger pricks, and interviews.

At the end of the baseline visit, research staff will randomly assign participants to the intervention or control group. The participant will wear a pedometer for seven consecutive days following this initial visit. The paper form for any information collected (e.g. consent form) will be stored in the CELLab at UNB in a locked cabinet. The CELLab has limited access; only staff has access through a password to the lab. All information will be linked to a participant number for which the only linkable personal information (e.g., name, age, sex) will be kept in a password protected computer and only the Principal Investigator, Co-Investigators, and Research Coordinator will have access to this information. Information will be stored for a maximum of 7 years.

Following this baseline assessment, participants in the intervention group will be assigned to an exercise program most convenient to them. This is a 12-week exercise program, offered twice a week. Full attendance is not mandatory for being a participant. This is a peer-led exercise program, meaning it is instructed by a leader of similar age. This leader has received extensive Fitness New Brunswick training to deliver a program aimed to reduce the risk of falls and help older adults safely increase their physical activity levels. This 60-minute exercise program involves aerobic and resistance exercise, as well as flexibility and balance activities. The program is currently designed to help individuals meet the physical activity guidelines. Participants' numbers will be used to register attendance from the leaders.

Following this 12-week intervention or control period, participants will repeat all the baseline assessments (including questionnaires and interviews), with an exception that they will not have to wear the pedometer in the follow up visit. The primary objective will be to determine whether participants' experiences with the program were positive or negative, and specifically identifying participants' attributions of why/how the exercise intervention positively impacted their physical and/or mental health.
