Differential Associations Between Device-Assessed and Parent-Reported Physical Activity With Indicators of Mental Health in Children and Youth With Disabilities.

Purpose: We examined associations between device-assessed and parent-reported physical activity with mental health indicators among children and youth with disabilities.

Method: Physical activity and mental health data were collected from a larger national surveillance study of physical activity in children and youth with disabilities in Canada. A total of 122 children and youth with disabilities (mean age = 10 y; 80% boys, 57% with developmental disability) wore a Fitbit for 28 days to measure their daily steps.

Linking 24-hour movement behaviour guidelines to core symptoms and school engagement of youth with moderate/severe ADHD.

Background: The independent associations of physical activity (PA), sleep duration (SL), and screen time (ST) with health outcome measures have been well-documented among children and adolescents, but not in youth with moderate/severe ADHD. To this end, the present study aimed to investigate the associations between three components within 24-hour movement behaviour (24-HMB) framework and core symptoms and school engagement in youth with moderate/severe ADHD.

Methods: This study used pooled data from the 2021-2022 U.

Predictive Utility of the Multi-Process Action Control Framework for Self-Reported and Device-Measured Physical Activity Behavior of Adolescents.

Understanding the correlates of physical activity behavior is imperative for informing the development of interventions to address the low rates of physical activity guideline adherence among adolescents living in the United States. This cross-sectional study examined the predictive utility of the Multi-Process Action Control (M-PAC) framework for explaining self-reported and device-measured physical activity behavior among a Hispanic-majority sample of adolescents. A total of 1849 high school students (mean age = 16.

Out-of-school Activities and Adherence to 24-hour Movement Guidelines.

Introduction: The purpose of this study was to explore associations between participation in out-of-school/weekend organized activities and adherence to the 24-hour movement guidelines among US adolescents.

Methods: Data from the 2022 National Survey of Children's Health (N=16,403, age=15.1±1.

Relations Among Multiple Dimensions of Self-Reported Listening Effort in Response to an Auditory Psychomotor Vigilance Task.

Purpose: Listening effort is a broad construct, and there is no consensus on how to subdivide listening effort into dimensions. This project focuses on the subjective experience of effortful listening and tests if cognitive workload, mental fatigue, and mood are interrelated dimensions.

Method: Two online studies tested young adults ( = 74 and = 195) and measured subjective workload, fatigue (subscales of fatigue and energy), and mood (subscales of positive and negative mood) before and after a challenging listening task.

Predicting physical activity behavior among university students using the multi-process action control framework.

Most university students do not engage in enough physical activity (PA) despite the known physical and mental health benefits. Action control theories such as the Multi-Process Action Control (M-PAC) framework have been proposed to better understand the translation of intentions into action by incorporating post-intentional processes. However, the explanatory power of the M-PAC framework beyond traditional social cognitive constructs has received limited attention.

The Effects of Mental Fatigue on Anaerobic Power and Power Endurance Performance.

Mental fatigue has been studied extensively in relation to its impact on aerobic-, strength-, and motor-based tasks, but anaerobic power-based tasks have received limited attention. Interdisciplinary research investigating the underlying mechanisms by which mental fatigue influences physical performance has been called for. In two studies, the effects of mental fatigue on maximal power jump and endurance jump performance as well as kinetics and kinematics during jump performance were examined.

Examining associations between physical activity context and children meeting daily physical activity guidelines: the role of outdoor play, sports, and other organized activities.

Background: Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas.

The Sport Experience Measure for Children and Youth (SEM:CY): A Rasch Validation Study.

This study employed Rasch analyses to validate a novel measure of sport experience: the Sport Experience Measure: Children and Youth (SEM:CY). Analyses were applied to self-reported data of n = 503 young people (age 9-18 years, M = 12.91, 50% female) in Canada who were engaging in sport during the previous 12 months.

Exercise identity and physical activity behavior during late adolescence: A four wave cross-lagged panel model.

Research has shown that physical activity behavior tends to decline across adolescence before stabilizing in adulthood. Identifying salient factors underlying these behavioral changes is therefore imperative for informing intervention development. This study explored the temporal nature of the relationship between exercise identity and physical activity behavior during the transition out of high school.

Independent and Joint Associations of Physical Activity and Sleep on Mental Health Among a Global Sample of 200,743 Adults.

Background: Previous research has demonstrated that both sleep and physical activity (PA) are independently associated with various indicators of mental health among adults. However, their joint contribution to mental health has received limited attention. The present study used cross-sectional data from the Mental Health Million Project to examine the independent and joint effects of sleep and PA on mental health among a global sample of adults, and whether these effects differ among individuals receiving mental health treatment.

Associations Between Intersecting Sociodemographic Characteristics and Device-Measured Physical Activity Among Children and Adolescents Living in the United States.

Background: Despite robust evidence demonstrating sociodemographic characteristics may underly some of the disparities in physical activity observed among children and adolescents, the often-overlooked nexus of potential interactions between these characteristics warrants further exploration. This study explored the intersectionality of gender, race/ethnicity, parental education, and household income in relation to device-measured physical activity volume and intensity in a nationally representative sample of US children and adolescents.

Methods: Cross-sectional data from 3 cycles of the US National Health and Nutrition Survey (2011-2012; 2012 National Youth Fitness Survey; and 2013-2014) were used.

The golden ratio in baseball: the influence of historical eras on winning percentages in major league baseball.

Introduction: The golden section or golden ratio (61.8% or 0.618) is a mathematical phenomenon that appears in art, literature, music and nature with such ubiquity that it is thought to be a fundamental principle of aesthetic organisation.

24-hour movement guideline adherence and mental health: A cross-sectional study of emerging adults with chronic health conditions and disabilities.

Background: Recent work has shown that individuals with chronic health conditions and disabilities (CCD) meet the 24-h movement guidelines at lower rates than population norms; however, the evidence base remains limited across different stages of the lifespan and very few studies have examined associations with mental health outcomes.

Objective: This study examined 24-h movement guideline adherence among emerging adults with CCD compared to those without and associations between guideline adherence and indicators of mental health.

Methods: This cross-sectional study used data from the 2020 cycle of the Canadian Campus Wellbeing Survey.

Development and evaluation of the IPLAY program: A protocol for a mixed-methods feasibility study targeting newcomer youth.

Background: Physical Literacy (PL) is a synthesis construct that ties together movement competencies with affective, motivational, and knowledge-based elements. It is considered foundational to the development of physical activity-related outcomes. Many diverse organizations and programs have embraced the concept and are implementing programs targeting each of those core elements.

Interactive Associations between Physical Activity and Sleep Duration in Relation to Adolescent Academic Achievement.

Purpose: The present study aimed to examine independent and interactive associations between physical activity and sleep duration with adolescent academic achievement.

Methods: This cross-sectional study used data from the 2019 cycle of the US-based Youth Risk Behavior Surveillance System. A total of 13,677 American adolescents in grades 9 through 12 (M = 16.

Healthier movement behavior profiles are associated with higher psychological wellbeing among emerging adults attending post-secondary education.

Background: Emerging adulthood is a stressful time fraught with new challenges while attending higher education. Identifying protective factors to help reduce the psychological burden that many will experience during this period is therefore important. This study aimed to identify whether emerging adults attending post-secondary education can be classified into distinct profiles based on their 24-h movement behaviors, evaluate correlates of profile membership, and examine relationships between profile membership and indicators of mental health.

Understanding Changes in Adolescent Physical Activity Behaviors and Cognitions Prior to and During the COVID-19 Pandemic.

Despite accumulating evidence that has found significant negative declines in physical activity (PA) as a result of the COVID-19 pandemic, little work has sought to understand how PA cognitions have changed during this period and in relation to behavior change during the pandemic. The purpose of the current study was to investigate the changes in adolescents' PA behaviors and cognitions associated with COVID-19 and prospective predictors of PA using the Multi-Process Action Control (M-PAC) framework. Adolescents were recruited from a large school board and a total of 588 participants (M = 15.

Cross-Sectional Associations Between Wake-Time Movement Compositions and Mental Health in Preschool Children With and Without Motor Coordination Problems.

Movement behaviors have been found to be important correlates of health for children and may be particularly important for children with Developmental Coordination Disorder (DCD) who often experience greater mental health problems. To date, however, little research has investigated the daily movement composition of preschool children with Developmental Coordination Disorder (DCD) and/or its association with mental health. The purpose of the current study was to: (1) examine whether differences in movement compositions (i.
