Postural stability is a complex skill dependent upon the coordination of motor, sensory and cognitive systems (Woollacott & Shumway-Cook, 2002). The purpose of this project was therefore to explore how older adults' balance performance is impacted by increased cognitive load, hearing loss, and simulated vision loss. Twenty-seven older adults between the ages of 56 and 90 years (M = 74.74, SD = 9.51) were tested. Participants underwent standard sensory acuity, and cognitive functioning tes...

Background: Recovery kinetics following cardiopulmonary exercise testing (CPET) have yet not been described in people with OSA and comorbid insomnia (COMISA). Our objectives were to i) describe heart rate recovery (HRR), oxygen recovery slopes (VO2/t) and time to half recovery of VO2max (T½) following CPET in COMISA; and ii) investigate their response to either one of the following: 16 weeks of exercise training (Ex) or 8 week-relaxation control intervention followed by 8 weeks of exercise an...

Childhood obesity and physical inactivity are growing problems across Canada, so the concept of physical literacy is used to promote physical activity (PA) participation in children. When children increase their PA participation, their exposure to musculoskeletal injury is also increased, but the concepts of physical literacy do not address...

Evidence consistently demonstrates that aging is associated with declines to cerebrovascular health. Sex distinctions have been identified as well, where studies have shown that cerebral blood flow (CBF) declines linearly across the lifespan in both sexes, yet females have greater CBF compared to males [1]. Cerebrovascular reactivity (CVR) has also been identified as a marker of cerebrovascular health and is shown to decline with age [1,2], but the potential sex differences are currently uncl...

The effects of physical inactivity among older adults have been established as a "public health crisis" because of their heightened risk of cardiovascular, autoimmune, neurocognitive, and mental health problems (Wu, 2020). While physical distancing is essential in the fight against COVID-19, long-term self-isolation protocols established to protect the elderly population have created new health risks, as older adults are now left more socially isolated and inactive than before. Making an inve...

Context: While soccer is considered a lateral dominant sport, few studies have examined if limb dominancy leads to asymmetries in body composition and their possible associations with injury (1). Objective: The purpose of this study was to 1) investigate body composition morphological asymmetries in male and female university-level soccer players, and 2) examine whether the degree of body composition asymmetry is associated with lower leg injuries (LLI) and lower back pain (LBP...
