Purpose : The purpose of this study was to explore how parent involvement influenced the effectiveness of a movement intervention targeting gross motor skills and physical activity behavior in preschool-aged boys and girls. Methods : Parents received training at monthly school-based sessions and online to implement the movement intervention once per month at school and once per week at home across 6 months ( N = 104; M age  = 48.30 months, SD  = 6.90). Children completed the Test of Gross Motor Development-3 at baseline and wore physical activity trackers 24/7 for six weeks during the intervention...

The continuous rise in opioid overdoses in the United States is predominantly driven by very potent synthetic opioids, mostly fentanyl and its derivatives (fentanyls). Although naloxone (NLX) has been shown to effectively reverse overdoses by conventional opioids, there may be a need for higher or repeated doses of NLX to revert overdoses from highly potent fentanyls. Here, we used positron emission tomography (PET) to assess NLX's dose-dependence on both its rate of displacement of [11 C]carfentanil ([11 C]CFN) binding and its duration of mu opioid receptor (MOR) occupancy in the male rat brain...

INTRODUCTION: The development of functional motor competence (FMC; i.e., neuromuscular coordination and control required to meet a wide range of movement goals) is critical to long-term development of health- and performance-related physical capacities (e.g., muscular strength and power, muscular endurance, and aerobic endurance). Secular decline in FMC among U.S. children and adolescents presents current and future challenges for recruiting prospective military personnel to successfully perform the physical demands of military duty...

BACKGROUND: The practice of physical activity (PA) plays an important role in achieving an active-healthy lifestyle. Several authors have focused their studies on the relationship between motor competence (MC) and physical activity (PA). Stodden et al. proposed a conceptual model, where they postulated the existence of a positive and significant relationship between the two variables and that there are mediating variables that play a critical role in this relationship as perceived motor competence (PMC)...

Background: Studies examining the physiological consequences associated with deficits in energy availability (EA) for male athletes are sparse. Purpose: To examine male athlete triad components; low energy availability (LEA) with or without an eating disorder risk (ED), reproductive hormone [testosterone (T)], and bone mineral density (BMD) in endurance-trained male athletes during different training periods. Methods: A cross-sectional design with 14 participants (age: 26.4 ± 4.2 years; weight: 70.6 ± 6.4 kg; height: 179...

Many interventions feature a singular component approach to targeting children's motor competency and proficiency. Yet, little is known about the use of integrative interventions to meet the complex developmental needs of children aged 3-6 years. The purpose of this study was to examine the effects of an integrative universally designed intervention on children with and without disabilities' motor competency and proficiency. We selected children (N = 111; disability = 24; no disability = 87) to participate in either a school-based integrative motor intervention (n = 53) or a control condition (n = 58)...

We investigated whether motor competence in fundamental motor skills influences sports motor skill learning. Motor competence in fundamental motor skills related to the overhead volleyball serve (i.e., throwing and volleying) was evaluated in 38 children (aged 9-10 yrs) and participants were divided into lower and higher motor competence groups. The groups practiced the volleyball serve under random or constant-random conditions during an acquisition phase and then assessed in pre-test, intermediate, and retention tests...

Purpose: The bidirectional associations among children's motor skill competence (MSC), perceived competence (PC), physical activity (PA), and cardiorespiratory fitness (CRF) over time remain unanswered. This study is aimed at discerning the bidirectional relationships among elementary school children's MSC, PC, PA and, CRF over the course of one school year. Methods: A total of 261 second and third grade children (127 boys, 134 girls; meanage = 8.27 years; BMI = 18...

INTRODUCTION: In 2008, a conceptual model explaining the role of motor competence (MC) in children's physical activity (PA), weight status, perceived MC and health-related fitness was published. OBJECTIVE: The purpose of the current review was to systematically compile mediation, longitudinal and experimental evidence in support of this conceptual model. METHODS: This systematic review (registered with PROSPERO on 28 April 2020) was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement...

The purpose of this study was to: (1) determine if process- and product-oriented measures similarly evaluate changes in motor skills across an intervention and (2) examine the relationship between preschoolers' motor skills when assessed using process-oriented and product-oriented measures before (pretest) and after (posttest) the intervention. Preschoolers ( n = 65, M age = 4.6±0.42 years) completed both process- and product-oriented measures of six FMS- run, hop, jump, catch, throw, and kick, before and after a high-autonomy motor skill intervention...

Purpose : Identifying profiles of preschoolers' motor competence (MC) is essential for providing accurate and targeted intervention. However, little is known regarding children's MC profiles, more specifically how skills may present in unique clusters. The purposes of the study were to explore MC profiles of U.S. children ages 3-6 years, quantify the uniqueness of these profiles, and examine differences by age, gender, race, geographic region, socioeconomic status, and Body Mass Index z -scores. Methods : Participants included children ( N = 582, n girls  = 296) aged 3-6 years ( M age  = 4...

Appropriate instruction is a key component of quality physical education, which aligns student learning activities with grade-level learning outcomes. Historically, in the 1980s and late 1990s, an abundance of research was conducted to empirically link teacher effectiveness to student learning outcomes. In recent years, however, limited research has been published. Purpose : The purpose of this study was to: (a) identify research studies examining appropriate instructional practice in K-12 physical education since 2000, (b) describe the study characteristics and summarize the findings, (c) compare research to the SHAPE America's guidelines for appropriate instruction, and (d) make recommendations for future research...

We carry out efforts to reproduce computational results for seven published articles and identify barriers to computational reproducibility. We then derive three principles to guide the practice and dissemination of reproducible computational research: (i) Provide transparency regarding how computational results are produced; (ii) When writing and releasing research software, aim for ease of (re-)executability; (iii) Make any code upon which the results rely as deterministic as possible. We then exemplify these three principles with 12 specific guidelines for their implementation in practice...

Decreased physical fitness in military recruiting populations is problematic for the development of physical military readiness (PMR) and presents a threat to national security. The demonstration of low levels of fitness may be an indicator of a more foundational problem in the physical development of military recruits. We propose the development of functional motor competence (FMC) across childhood and adolescence as a necessary antecedent to advanced PMR training and military-specific tasks (i.e., rucking and obstacle course navigation) and as an integral part of sustained PMR...

In the 2018 meta-analysis of Educational Psychology Review entitled "Null effects of perceptual disfluency on learning outcomes in a text-based educational context" by Xie, Zhou, and Liu, we identify some errors and inconsistencies in both the methodological approach and the reported results regarding coding and effect sizes. While from a technical point of view the meta-analysis aligns with current meta-analytical guidelines (e.g., PRISMA) and conforms to general meta-analytical requirements (e.g., considering publication bias), it exemplifies certain insufficient practices in the creation and review of meta-analysis...

Purpose : This introductory article provides the context and rationale for conducting systematic literature reviews on each of the essential components of physical education, including policy and environment, curriculum, appropriate instruction, and student assessment. Methods : Four research teams from Doctoral Physical Education Teacher Education programs (D-PETE) conducted these systematic reviews using the PRISMA guidelines process. Results : This article explains the role of the national framework for increasing physical education and physical activity (i...

Neutrophilic inflammation results in loss of lung function in chronic obstructive pulmonary disease (COPD). Gram-negative bacteria, such as nontypeable Haemophilus influenzae (NTHi), trigger acute exacerbations of COPD (AECOPD) and contribute to chronic lung inflammation. The pro-inflammatory cytokine interleukin-17C (IL-17C) is expressed by airway epithelial cells and regulates neutrophilic chemotaxis. Here, we explored the function of IL-17C in NTHi- and cigarette smoke (CS)-induced models of COPD. Neutrophilic inflammation and tissue destruction were decreased in lungs of IL-17C-deficient mice (Il-17c-/-) chronically exposed to NTHi...

Children with visual impairments typically demonstrate lower levels of motor competence, physical activity, and perceived motor competence compared to their peers without visual impairments. Stodden and colleagues purport that perceived motor competence mediates the relationship between motor competence and physical activity for youth without visual impairments. Purpose:  The purpose of this study was to test whether perceived motor competence mediates the relationship between motor competence and physical activity for youth with visual impairments...
