Current Collaborations
Our research in exercise medicine sometimes overlaps and complements the research of other Labs. Often we will collaborate with other researchers, providing them with data we have gathered through our studies.
Here are some of our current Research Collaborations.

Physical activity during early childhood (<5 years), typically regarded as active play, is necessary to support young children’s
achievement of developmental milestones. Despite the importance of physical activity during early childhood, opportunities
to engage in this behaviour in childcare remain infrequent and under-valued. Early childhood educators (ECEs) are crucial for
supporting physical activity in this environment, as they have had a profound influence on children’s physical activity
opportunities. However, ECEs have reported low self-efficacy to lead physical activity in childcare, which they have
attributed to their limited training in this area. Inconsistencies in physical activity education exist across Canadian pre-service
ECE programs; as such, our team led the SSHRC-funded Training pre-service EArly CHildhood educators in physical
activity (TEACH) study to develop and implement an e-Learning course in physical activity with pre-service ECEs.
Full-scale implementation in 20 Canadian English-speaking ECE programs is underway; however, to
ensure equitable access to this professional learning opportunity for all Canadian pre-service ECEs, and to address the
imminent need for high-quality virtual learning in post-secondary programs due to COVID-19, translating and adapting the
course into French (TEACH-FR) and testing its effectiveness in a timely manner is necessary.
The goals of this study are to: i) Establish whether the TEACH-FR e-Learning course can increase French-speaking
pre-service ECEs’ physical activity self-efficacy, knowledge, and intentions (Primary Objectives) and ii) Explore the
feasibility, fidelity, and reach, of the course, and gather pre-service ECEs’ and instructors’ perspectives about the content and
delivery (Secondary Objectives).
Developmental Coordination Disorder (DCD) is a prevalent neurodevelopmental disorder affecting 5-6% of children. DCD is characterized by significant problems with fine and/or gross motor coordination that impair a child’s ability to perform many everyday tasks. Our research team has led the field internationally in understanding how this condition puts children at risk for inactivity and poor health-related fitness outcomes during mid-childhood through adolescence. Starting in 2013, our team successfully assembled a large cohort of 4- and 5-year-old children with probable DCD (pDCD) (total 589 children; 288 pDCD). We are requesting new funding to continue this unique cohort of children to examine their trajectories of physical activity (PA) as they transition from early to late-childhood and determine how psychosocial, behavioural and physical factors influence their risk of developing mental health problems.
The overall goal of the Coordination and Activity Tracking in Children II (CATCH II) continuation study is to determine if: 1) young children with pDCD are more likely to experience declines in PA, and increases in body weight over time; and 2) if changes in PA, health-related fitness, and psychosocial factors explain increased self-reported internalizing problems (depression/anxiety) as they transition to late-childhood.
We propose developing and evaluating a pediatric concussion management health platform available on mobile devices. The proposed platform will be based upon advanced ML methods applied to the management of recovery after concussion in youth. Based on previous findings of the applicants, the proposed system has the potential for significant improvements in concussion management over currently employed methods. The proposed project will bring about the ability for youth and their families along with clinicians to assess recovery and modify their activity to promote speedy recovery, prevent repeat injuries and prolonged symptom duration which will interfere with participation in normal activities and increase the possibility of developing devastating chronic symptoms along with depression, anxiety and academic failure.
Physical activity during early childhood (<5 years), typically in the form of active or energetic play experiences, is necessary to support young children’s achievement of developmental milestones. Despite the importance of physical activity during early childhood, opportunities to engage in this behaviour in childcare remain infrequent and under-valued. Early childhood educators are crucial for supporting physical activity in this environment, as they control a substantial portion of young children’s days and can profoundly influence physical activity opportunities within the childcare setting. However, early childhood educators have reported low self-efficacy to lead physical activity in childcare and have reported that this is due primarily to their limited post-secondary training in physical activity.
Inconsistencies in physical activity-related training and education exist across Canadian Early Childhood Education (ECE) diploma programs; as such, an innovative pedagogical approach is needed to ensure ECE candidates develop appropriate knowledge and self-efficacy in physical activity domains to be confident leading physical activity opportunities in childcare settings.
The goals of this study are to: i) Establish whether a physical activity e-Learning module increases ECE candidates’ physical activity-related self-efficacy (Objective #1) and knowledge (Objective #2); and, ii) Examine the acceptability, feasibility, and fidelity of module implementation; and gather ECE candidates’ use of, perspectives about, and experiences with the content and mode of delivery (Objective #3).
