Although social distancing directives are important public health measures to reduce the spread of SARS-cov-2, they can contribute to negative emotional outcomes such as loneliness due to the isolation. Furthermore, individuals have been reporting poorer sleep quality since the beginning of the COVID-19 pandemic. The aim of this study is to...
Background: Cellular senescence, cell growth cycle arrest, is a marker of cellular aging. Obesity is considered a disease of accelerated aging as it shares several co-morbidities with aging, such as type 2 diabetes mellitus (T2DM). Objective: To determine regional differences in markers of cellular senescence and how these compare in obese individuals with and without T2DM. Methods: Pre-menopausal females undergoing bariatric surgery were categorized as obese-metabolically healthy...
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...
Background: To create games that target older adults' interests in engaging in cognitively-boosting activities is a rising trend [1,2]. But, the novelty of the digital me-dium of play, and the implicit expectation of cognitive performance can create stressful experiences for them [3]. We have previously proposed an empirical framework, Affective Game Planning for Health Applications (AGPHA) based on Lazarus's Transactional Theory of Stress Appraisal and Coping [4], to study interactions betwe...
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...
Efficient neural transmission is crucial for optimal brain function, yet the plastic potential of white matter (WM) has long been overlooked. Growing evidence now shows that modifications to axons and myelin occur not only as a result of long-term learning, but also after short training periods [1]. Motor sequence learning (MSL) has been shown to occur in overlapping learning stages where different neural circuits are involved at each stage [2]. However, most studies investigating short-term ...
Background: During atherosclerotic plaque development, vascular smooth muscle cells (VSMC) undergo dedifferentiation, resulting in a synthetic, less contractile progenitor state. This transition is marked by changes in mitochondrial respiration and increased reactive oxygen species (ROS) production. These changes in bioenergetics play a critical role in atherogenesis via facilitation of VSMC migration towards the intima. Objective: The objective of this study was to evaluate t...
According to the oxidative stress theory, reactive species are key drivers of inflammation and cardiovascular disease (1). The electron transport chain of the mitochondria accounts for ≈90 of the intracellular radioactive oxygen species (2). Interestingly, while low-carbohydrate high-protein diets promote weight loss, animal experiments show that they could also lead to mitochondrial dysfunction and therefore, oxidative stress and inflammation (3). In parallel, research in the last decade has...
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...
Introduction: Right to left asymmetries in body composition has been examined across many sports, suggesting possible implications for lower back pain (LBP) and decreased level performance. However, we are not aware of any study that has examined the presence and implications of morphological asymmetries in ice hockey players. The purpose of this study was to 1) investigate body composition asymmetries in female and male university level ice hockey players and 2) examine whether the degree of...
