Mental health symptom burden in elite ice hockey players and its association with self-reported concussive events.

Background: Some studies suggest that elite athletes experience adverse mental health symptoms at rates commensurate with the general population, despite the well-established buffering effects of exercise. Within contact sports, such as ice-hockey, recurrent concussions may be a source of this discrepancy. We compared the point prevalence of various mental health outcomes with other athlete and general population samples, as well as investigated their relationship with concussive events.

Age, Sex, and Training Specific Effects on Cross-Education Training.

An extensive number of publications have examined cross-education effects with adults, primarily investigating contralateral homologous (same) muscles. There are far fewer investigations on cross-education effects on contralateral heterologous (different) muscles and age (youth vs adult) and no studies investigating sex differences. Hence, the objective was to compare cross-education in female and male youth and young adults to contralateral homologous (chest press [CP], elbow flexors and extensors, handgrip isometric strength, and shot put) and heterologous (leg press, knee extension isometric strength, and countermovement jump) muscles.

Co-creating a yoga program for women diagnosed with gynecologic cancer: a consensus study.

Purpose: Yoga may be uniquely suited to address bio-psycho-social concerns among adults with gynecologic cancer because it can be tailored to individuals' needs and can help shift focus inward towards self-reflection, body appreciation, and gratitude. This study describes the collaborative process guided by the Knowledge-to-Action framework used to develop a yoga program for adults diagnosed with gynecologic cancer and inform a feasibility trial.

Methods: In 3 collaborative phases, yoga instructors and women diagnosed with gynecologic cancer formulated recommendations for a yoga program and evaluated the co-created program.

An exploratory investigation of heart rate and heart rate variability responses to daylong heat exposure in young and older adults.

Heart rate variability (HRV) has shown potential as a tool for monitoring thermal strain, but there is limited data to support its efficacy in older adults during prolonged heat exposures. We compared HRV between young (19-31 years,  = 20) and older (61-78 years,  = 39) adults during 9 h of heat exposure (40 °C, 9% RH). We also explored whether heart rate (HR) and/or HRV could be used to distinguish older adults who achieved elevated thermal strain, defined as either (1) an increase in core temperature >1.

Effect of 1800 MHz radiofrequency field exposure on cytokine and signal transduction protein expression in differentiated THP-1 cells.

Purpose: To evaluate the effects of 1800 MHz continuous wave (CW) and global system for mobile communications (GSM) modulated radiofrequency electromagnetic field (RFEMF) exposures on signal transduction (ST) protein and cytokine expression in differentiated human-derived monocytic THP-1 cells.

Materials And Methods: THP-1 cells were differentiated into adherent macrophage-like cells using phorbol 12-myristate 13-acetate (PMA). Following differentiation, cells were exposed to 1800 MHz CW or GSM modulated RFEMF for 0.

Media-Based Post-Event Impact Analysis of the 2021 Heat Dome in Canada.

The unprecedented 2021 Heat Dome caused wide-ranging and long-lasting impacts in western Canada, including 619 confirmed heat-related deaths in British Columbia, a doubling of emergency medical calls, increased hospitalisations, infrastructure failures and stress on plants and animals. However, such varied socio-economic consequences of extreme heat can be challenging to capture using a single post-event analysis method. Therefore, there is a need to explore alternative approaches and data sources.

Physiological fitness in people with advanced multiple sclerosis.

Introduction: Physiological fitness, encompassing cardiorespiratory fitness (CRF) and body composition, are important markers of overall health, functional capacity, and quality of life in general and clinical populations. Characterizing fitness is important for the development of tailored interventions and strategies to optimize well-being across the spectrum of disability in multiple sclerosis (MS). While existing research has explored fitness in people with mild-to-moderate disability, there is a scarcity of data in people with advanced MS (Expanded Disability Severity Scale, EDSS≥7.

Head and neck cooling enhance exercise tolerance in individuals with multiple sclerosis.

Background: Individuals with Multiple Sclerosis (MS) experience impairments in heat dissipation, compromising core temperature regulation during exercise.

Objective: To examine the efficacy of combined head-and-neck cooling as administered via a commercially available cooling cap and neck wrap in mitigating increases in core temperature during exercise.

Methods: On separate days, ten (7 females) adults (46.

Modulation of cutaneous vasodilation by reactive oxygen species during local and whole body heating in young and older adults.

We evaluated reactive oxygen species (ROS) modulation of cutaneous vasodilation during local and whole body passive heating in young and older adults. Cutaneous vascular conductance normalized to maximum vasodilation (%CVC) was assessed in young and older adults (10/group) using laser-Doppler flowmetry at four dorsal forearm sites treated with ) Ringer solution (control), ) 100 µM apocynin (NADPH oxidase inhibitor), ) 10 µM allopurinol (xanthine oxidase inhibitor), or ) 10 µM tempol (superoxide dismutase mimetic), via intradermal microdialysis during local () and whole body heating (). In , forearm skin sites were set at 33°C during baseline and then progressively increased to 39°C and 42°C (30 min each).

Sex Differences in Changes in Cardiorespiratory Fitness and Additional Health Outcomes Following Exercise Training in Adults With Atrial Fibrillation: A Systematic Review and Meta-Analysis.

Purpose: Improving cardiorespiratory fitness (CRF) through exercise training is associated with lower morbidity and mortality in patients with atrial fibrillation (AF). Smaller CRF improvements have been suggested in females than males with cardiovascular disease following exercise training. This systematic review compared changes in CRF (primary) and additional physical and mental health outcomes following exercise training between females and males with AF.

Disordered eating behaviours during the menopausal transition: a systematic review.

Disordered eating refers to a range of eating behaviours and attitudes towards weight and food that can negatively influence physical and psychosocial well-being. The menopausal transition could be a vulnerable period for disordered eating due to major hormonal fluctuations, menopausal symptoms, common body composition shifts, and an increased risk of psychological challenges. This systematic review aimed to summarize evidence on the associations between the menopausal transition and disordered eating.

The Effects of Static Stretching 2-Hours Prior to a Traditional Warm-Up on Performance.

Whereas prolonged static stretching (SS: >60-seconds per muscle) can increase range of motion (ROM) for up to 2-hours, it can also decrease maximal voluntary isometric contraction (MVIC) forces, countermovement (CMJ) and drop jump (DJ) heights, and muscle activation immediately after the stretching exercise. When an appropriate SS duration (<60-seconds per muscle) is incorporated into a dynamic warm-up, performance decrements are often trivial. However, there is a lack of studies that observed the effects of extensive SS (180-seconds) 2-hours prior to a dynamic warm-up.

Clinician-Prioritized Measures to Use in a Remote Concussion Assessment: Delphi Study.

Background: There is little guidance available, and no uniform assessment battery is used in either in-person or remote evaluations of people who are experiencing persistent physical symptoms post concussion. Selecting the most appropriate measures for both in-person and remote physical assessments is challenging because of the lack of expert consensus and guidance.

Objective: This study used expert consensus processes to identify clinical measures currently used to assess 5 physical domains affected by concussion (neurological examination, cervical spine, vestibular, oculomotor, or effort) and determine the feasibility of applying the identified measures virtually.

Responding to the Heat and Planning for the Future: An Interview-Based Inquiry of People with Schizophrenia Who Experienced the 2021 Heat Dome in Canada.

People with schizophrenia have died at disproportionately higher rates during recent extreme heat events (EHEs) in Canada, including the deadly 2021 Heat Dome in British Columbia (B.C.).

An Ideal Intervention for Cancer-Related Fatigue: Qualitative Findings from Patients, Community Partners, and Healthcare Providers.

Patients consistently rate cancer-related fatigue (CrF) as the most prevalent and debilitating symptom. CrF is an important but often neglected patient concern, partly due to barriers to implementing evidence-based interventions. This study explored what an ideal intervention for CrF would look like from the perspectives of different stakeholders and the barriers to its implementation.

Indoor overheating: A review of vulnerabilities, causes, and strategies to prevent adverse human health outcomes during extreme heat events.

The likelihood of exposure to overheated indoor environments is increasing as climate change is exacerbating the frequency and severity of hot weather and extreme heat events (EHE). Consequently, vulnerable populations will face serious health risks from indoor overheating. While the relationship between EHE and human health has been assessed in relation to outdoor temperature, indoor temperature patterns can vary markedly from those measured outside.

Voluntary co-contraction of ankle muscles alters motor unit discharge characteristics and reduces estimates of persistent inward currents.

Motoneuronal persistent inward currents (PICs) are facilitated by neuromodulatory inputs but are highly sensitive to local inhibitory circuits. Estimates of PICs are reduced by group Ia reciprocal inhibition, and increased with the diffuse actions of neuromodulators released during remote muscle contraction. However, it remains unknown how motoneurons function in the presence of simultaneous excitatory and inhibitory commands.

Changes in appetite during acute passive intermittent and continuous hypoxemia in postprandial and fasting states: A combined analysis of four laboratory-based randomized crossover trials.

Hypoxemia occurs during exposure to high altitude (continuous hypoxemia) or in the context of breathing disorders such as obstructive sleep apnea (OSA; intermittent hypoxemia). Growing evidence demonstrates that hypoxemia induces an anorexigenic effect on appetite; however, few studies have assessed hypoxemia-related reductions in appetite during acute passive exposures and during intermittent hypoxemia. This study thus pooled together four same-single-site randomized crossover trials using simulated models of high altitude (fraction of inspired oxygen = 0.

Energy balance and obesity: the emerging role of glucagon like peptide-1 receptor agonists.

Purpose Of Review: With obesity affecting over one billion people globally, understanding and managing this complex condition is more crucial than ever. This review explores the emerging role of GLP-1 receptor agonists (GLP-1RA) in weight management, focusing on their impact on energy balance. It highlights the necessity of this investigation due to the limited knowledge on both the short-term and long-term implications of GLP-1RA on energy expenditure (EE) and energy intake (EI).

The effects of mental fatigue on explicit and implicit contributions to visuomotor adaptation.

The goal of the current research was to establish the impact of mental fatigue on the contributions of explicit (i.e., conscious strategy) and implicit (unconscious) processes to visuomotor adaptation.

The effect of foot immersion and neck cooling on cardiac autonomic function in older adults exposed to indoor overheating: a randomized crossover trial.

Foot immersion and neck cooling are recommended cooling strategies for protecting heat-vulnerable persons during heat waves. While we recently showed that these strategies do not limit core temperature increases in older adults during prolonged heat exposure, we did observe small reductions in heart rate. Expanding on these findings, we examined the effects of foot immersion with and without neck cooling on cardiac autonomic function.

An intense electrical stimulus can elicit a StartReact effect but with decreased incidence and later onset of the startle reflex.

Planned actions can be triggered involuntarily by a startling acoustic stimulus (SAS), resulting in very short reaction times (RT). This phenomenon, known as the StartReact effect, is thought to result from the startle-related activation of reticular structures. However, other sensory modalities also can elicit a reflexive startle response.
