Physical Activity Clinical Trials in Canada

The proposed study aims to improve the psychosocial health of adolescents living with type 1 diabetes (T1D). The study will generate knowledge and support knowledge mobilization about the effectiveness of a novel model of care for psychosocial health and self-management for adolescents living with type 1 diabetes (T1D). The novel model of care is the recruitment and training if young adult mentors to deliver a behavioural intervention that empowers adolescents with T1D to increase daily physical activity. The study will also advance the development and implementation of this peer mentoring model to improve the psychosocial health of adolescents with T1D. Read Less

The goal of this trial is to find out whether adding identity-building and self-regulation training to basic healthy-living education helps families with inactive children (ages 6-12) become more cohesive and physically active. The main question it aims to answer is: Does the identity + self-regulation + education program improve family cohesion more than (a) self-regulation + education or (b) education alone? Researchers will compare three groups-identity+self-regulation+education (ID), self-regulation+education (SR), and education-only (ED)-to see which produces the greatest improvements. Participants will: 1. attend three online workshops at baseline plus two booster sessions at 6-week and 3-month with a project coordinator; 2. complete online questionnaires at baseline, 6-week, 3-month, and 6-month; 3. take part in an exit interview at 6 months.

The purpose of this study is to examine physical activity habit formation in parents and if this can increase moderate to vigorous physical activity behavior in their children over six months.The Primary Research Question is: Does the habit formation condition result in increased moderate-vigorous intensity physical activity of the child compared to the control (education) and education + planning conditions at six months? Hypothesis: Child physical activity will be higher for the habit formation condition in comparison to the more standard physical activity education and planning conditions at six months. Read Less

The purpose of our study is to explore the effectiveness of physical activity (PA) identity formation in the family system as a promotor of long-term PA. The primary research question is: Does a family identity formation condition (with education+planning) result in increased child moderate- to vigorous-intensity PA (MVPA) compared to a standard comparison education and planning condition at six months? Hypothesis: Child MVPA will be higher for the identity formation condition in comparison to the more standard PA education+planning condition at six months. Read Less

Post-secondary students report alarming rates of feeling overwhelmed, hopeless, anxious, and depressed. To better support student mental health, there is a well-documented need to improve the range and quality of mental health services available to students. Focussing on formalized treatment approaches and strategies supporting well-being in the campus community more generally are needed. Physical activity is an alternative therapeutic approach that could be implemented as an evidence-based lifestyle intervention for supporting mental health and well-being on post-secondary campuses. Despite the growing evidence supporting physical activity for student mental health, there are significant knowledge gaps in the literature. First, there is a paucity of research exploring the effects of different delivery styles (i.e., one-on-one (1:1) vs. group) on primary (i.e., mental health symptomology including anxiety symptoms, depression symptoms, psychological distress) and secondary (i.e., social support, social connectedness) outcomes. Secondly, the maintenance effects of a physical activity program on mental health or sustained physical activity behaviour change are largely unknown. Lastly, limited research has explored contextual implementation factors (e.g., intervention reach, adherence, and program satisfaction) that may influence the sustainability and scale-up of physical activity programs for student mental health. Examining contextual implementation factors is critical for optimizing physical activity intervention delivery and for facilitating wider dissemination of research findings into practice. The goal of this 3-arm parallel randomized controlled trial is to test the effectiveness of 1:1 physical activity intervention and group-based physical activity intervention compared to a wait-list control group in supporting post-secondary student mental health. The main questions include: * Are there group differences between 1:1, group-based delivery, and waitlist control in the immediate (post-intervention) and follow-up (1-month) maintenance effects on the primary and secondary outcomes? * Grounded in recommendations for process evaluation of complex interventions, what are contextual implementation factors that may be linked to variation in primary and secondary outcomes while offering insight for wider dissemination? Trial participants will be randomly assigned to one of the following groups: 1. 1:1 physical activity training; 2. Group-based physical activity training consisting of small 5-8 person groups; or 3. Waitlist control. Students will participate in the physical activity intervention after the intervention and follow-up period (10 weeks); however, their participation will not be monitored or evaluated. The physical activity training will involve a 6-week physical activity intervention consisting of weekly 1-hour sessions. Each session involves: (1) 30-minutes of behaviour change coaching (e.g., goal setting, action-planning, brainstorming strategies to overcome barriers to engaging in physical activity); and (2) 30-minutes of supervised and structured physical activity training. To address the aims of the study, participants will complete self-report questionnaires at baseline, post-intervention (following completion of the 6-week physical activity intervention), and 1-month following completion of the physical activity intervention. Questionnaires will assess demographic characteristics, primary outcomes (i.e., mental health symptomology including anxiety symptoms, depression symptoms, psychological distress), secondary outcomes (i.e., social support, social connectedness, physical activity behaviour) and contextual implementation factors (e.g., intervention reach, adherence, and program satisfaction) that may be linked to variation in primary and secondary outcomes while offering insight for wider dissemination. It is hypothesized that there will be no group differences between 1:1 delivery and group-based delivery on the primary outcomes. It is also hypothesized that group-based delivery, in comparison to 1:1 delivery will achieve greater improvements and more favourable maintenance effects in the secondary outcomes. Lastly, it is hypothesized that in comparison to the control group, 1:1 delivery and group-based delivery will be more effective in achieving change in the primary and secondary outcomes. Read Less

While it is well established that physical inactivity is a modifiable risk factor for vascular disease and cognitive decline, the mechanism by which exercise exerts its protective effect on the cerebral circulation and cognition is unknown. This knowledge gap was recognized recently in the Centers for Disease Control \& Prevention and the Alzheimer's Association document "National Public Health Road Map to Maintaining Cognitive Health". Our rationale for these studies is that the identification of physical exercise as a lifestyle factor able to improve cerebrovascular reserve and cognition would establish a strong scientific framework justifying design of a randomized clinical trial that could evaluate the role of physical activity in cerebrovascular health and function. This research is based on data we obtained from a cross-sectional study that showed significant relations between physical fitness, vascular regulation and cognition. Cerebrovascular reserve and cognition were better maintained in women who were physically active but reduced in women who were sedentary. Our central hypothesis is that regular aerobic exercise mitigates age-related decreases in cerebrovascular reserve, which in turn imparts benefits in cognition. Further, we believe that these effects will persist after the structured aerobic exercise program is terminated. Our 18 month study began with a 6-month baseline period, followed by a 6-month exercise intervention, and a 6-month follow-up period. In addition, there are 5-year and 10-year follow-up periods. Volunteers (men and women aged ≥ 55 years) from the community were recruited using a variety of recruitment methods including media and distribution lists. After the baseline (pre-training) measurements, participants underwent a six-month aerobic training program, following guidelines previously used by us and according to the new exercise guidelines for older adults established by American College of Sports Medicine and the American Heart Association. The study involves comprehensive assessments of physical fitness, cerebrovascular responses to carbon dioxide at rest and during sub-maximal exercise, and an extensive battery of cognitive function tests.
