Affective experiences have been shown to influence attitudes and future behaviors related to physical activity, but no studies have related these experiences to physical literacy or examined affective experiences in quality physical education (QPE). The aim of this study was to describe emotions experienced in a QPE context and relate those emotions to students' physical literacy and self-esteem. A cross-sectional study of 145 4th and 5th grade students was surveyed after a single PE class on their emotional experiences (positive emotions: pride, enjoyment, and relief; negative, emotions: shame, anger, and boredom; aggregate emotional experience as the sum of positive and negative emotions) physical literacy (self-description and movement valuation) and self-esteem.

Introduction: In recent years, there has been a call to restructure physical education (PE) practices and outcomes. A physical literacy enriched pedagogy approach would support this change by more intentional design of lesson planning that includes concurrent development of competence & confidence and inclusion of students of all levels of ability, leading to holistic development of the student. Despite this potential, there is little research to date that outlines PE pedagogical practices with physical literacy as a foundation.

Background: Children, on average, do not engage in sufficient physical activity to reap the physical, mental, and social health benefits. Understanding the value that children place on movement across social contexts, and the relative ranking of this valuation, may help us to understand and intervene on activity levels.

Method: This exploratory study examined the valuation of reading/writing, math, and movement across three social contexts (school, home, with friends) among children 6-13 years of age (= 7,845; 51.

Background: Acute management of trauma patients with potential spine injuries has evolved from uniform spinal immobilization (SI) to spinal motion restriction (SMR). Little research exists describing how these changes have been implemented. This study aims to describe and analyze the practice of SMR in one emergency medical services (EMS) agency over the time frame of SMR adoption.

Objective: The circus professionalization process entails extensive training to mitigate the high-risk demands which increase stress in artists. In high-risk professions, everyday hassles (challenges) contribute greatly to overall stress. To capture the impact of daily challenges on student-artists, the aim of the current study was to describe the magnitude and pattern of daily challenges as well as their relationships with perceived coping, anxiety, fatigue, and psychological distress.

Background: The optimal application of spinal motion restriction (SMR) in the prehospital setting continues to be debated. Few studies have examined how changing guidelines have been received and interpreted by emergency medical services (EMS) personnel. This study surveys paramedics' attitudes, observations, and self-reported practices around the treatment of potential spine injuries in the prehospital setting.

Introduction: The paramedic practice environment presents unique challenges to data documentation and access, as well as linkage to other parts of the healthcare system. Variable or unknown data quality can influence the validity of research in paramedicine. A number of database quality assessment (DQA) frameworks have been developed and used to evaluate data quality in other areas of healthcare.

The COVID-19 pandemic resulted in the abrupt closure of circus schools, venues, and companies, introducing a myriad of novel stressors. Performers and students must now attempt to maintain their technical, physical, artistic, creative, and cognitive abilities without in-person support from their coaches and must manage the isolation from their training and performing spaces. For circus artists, the transposition of the work space to a home environment is not possible, which creates novel stressors that could lead to the exacerbation and escalation of mental health issues.

Background: Spinal precautions are intended to limit motion of potentially unstable spinal segments. The efficacy of various treatment approaches for motion restriction in the cervical spine has been rigorously investigated using healthy volunteers and, to a lesser extent, cadaver samples. No previous studies have objectively measured this motion in trauma patients with potential spine injuries during prehospital care.

There is growing interest in the relationship between physical and psychosocial factors related to resilience to better understand the antecedents of health and successful adaptation to challenges in and out of school, and across the lifespan. To further this understanding, a trans-disciplinary approach was used to investigate the association between the multidimensional constructs of physical literacy and resilience in children at a key stage in their development. Cross-sectional data were collected from 227 school children aged 9-12 years old from five schools in Winnipeg, Manitoba, Canada.

: The purpose of this study was to examine the convergent validity of the PLAYfun tool, a physical literacy-based measure of movement competence, by examining its association with objectively measured physical activity in a sample of children and youth. : Participants included 110 children between the ages of seven to 14 years attending a stratified random sample of 27 afterschool programs across the province of Ontario, Canada. The PLAYfun tool was administered to the participants on one occasion at their afterschool program and then they were asked to wear a pedometer for seven consecutive days to measure their physical activity levels.

Aims: The development of elite circus artists requires extensive technical and artistic training, as well as a commensurate level of physical preparation in readiness for a demanding professional career as a performance artist. While sport research has identified the importance of monitoring sleep and fatigue in athletes to optimize performance and to prevent illness and injury, not a single study of circus artists exists. This study provides a longitudinal examination of sleep and fatigue in elite circus student-artists.

Physical literacy (PL) provides a powerful lens for examining movement in relation to physical activity (PA) and motor skill outcomes, environmental context, and broader social and affective learning processes. To date, limited consideration has been given to the role PL plays in promoting positive health behaviours. There is no clear conceptual framework based on existing empirical evidence that links PL to health, nor has an evidence-informed case been made for such a position.

Background: There is an absence of information regarding the impact of central adiposity on loading during long duration, repetitive lifting, and very limited information of the impact of elevated body mass on mechanical loading of the lumbar spine. This information is important in evaluation of the validity of injury prevention standards and interventional approaches in this segment of the population.

Methods: This study evaluated the mechanical, physiological, and perceptual loading during repetitive lifting in participants with central adiposity compared to participants with normal body mass index.

Introduction: Physical Literacy Assessment for Youth (PLAYfun) is a measure of motor competence, comprehension, and confidence which is part of a suite of scales used to assess physical literacy in children and youth; however, its measurement properties have not been reported in the published literature. The purpose of this study is to examine the factor structure of PLAYfun, in addition to variations in PLAYfun subscale results by age and sex.

Method: In this study, we use a sample of children and youth 7 to 14 yr of age (n = 215) to test a proposed factor structure for the motor competence component of PLAYfun and to examine age and sex differences in subscale and total scores.
