The Effects of an Integrative, Universally Designed Motor Skill Intervention for Young Children With and Without Disabilities.

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.

Standing Long Jump Performance in Youth with Visual Impairments: A Multidimensional Examination.

Muscular fitness, an important marker of health in youth, includes explosive strength, which can be assessed using the standing long jump (SLJ). Little is known concerning the SLJ in populations with disabilities such as youth with visual impairments (VI) who trend with decreased health- and performance-related outcomes. The purposes of this study were to investigate multidimensional SLJ performance outcomes in youth with VI (i.

The Brief Form of the Test of Gross Motor Development-3 for Individuals with Visual Impairments.

Children with visual impairments (VI) tend to struggle with their fundamental motor skills (FMS), and these difficulties often persist across the lifespan, requiring frequent assessment. The Test of Gross Motor Development (TGMD) shows robust psychometric properties for children with VI. The TGMD, which includes 13 skills, is time-consuming to administer and score, warranting the need to explore brief versions.

An Examination of Motor Competence Profiles in Preschool Children: A Latent Profile Analysis.

: 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.

Changes in joint kinematics and dynamic postural stability with free and restricted arm movements in children.

Background: Arm movements make a substantial and functionally relevant contribution to quiet standing and dynamic balance tasks. The impact of restricted arm movements on balance control is particularly important for children as their postural control system is not fully matured.

Research Question: This study investigated the effects of arm movements on lower body joint kinematics and dynamic postural stability during anterior and lateral dynamic movements in children.

Longitudinal Locomotor Competence and Body Mass Index Across Self-Reported Gender and Vision Level for Youth With Visual Impairments: A 3-Year Investigation.

Youth with visual impairments are more likely to be overweight than peers without visual impairments and often struggle with their locomotor skills. Locomotor development can combat unhealthy body weight statuses by supporting physical activity behaviors. There are no longitudinal investigations concerning the locomotor skill and body mass index (BMI) developmental trajectories of youth with visual impairments.

Perceived Motor Competence Mediates the Relationship Between Gross Motor Skills and Physical Activity in Youth With Visual Impairments.

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.  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.

The Effects of Ecologically Valid Intervention Strategies on the Locomotor Skills of Children With Visual Impairments.

Children with visual impairments often exhibit difficulties with locomotor skills (e.g., the ability to move one's body from one place to another), warranting the need for ecologically valid interventions with conditions that attempt to match the real world in a variety of settings.

A Systematic Review and Qualitative Synthesis Resulting in a Typology of Elementary Classroom Movement Integration Interventions.

Motor Competence Levels and Developmental Delay in Early Childhood: A Multicenter Cross-Sectional Study Conducted in the USA.

Background And Objectives: Developmental delay in motor competence may limit a child's ability to successfully participate in structured and informal learning/social opportunities that are critical to holistic development. Current motor competence levels in the USA are relatively unknown. The purposes of this study were to explore motor competence levels of US children aged 3-6 years, report percentages of children demonstrating developmental delay, and investigate both within and across childcare site predictors of motor competence, including sex, race, geographic region, socioeconomic status, and body mass index percentile classification.

Dynamic Postural Control in Children: Do the Arms Lend the Legs a Helping Hand?

There is growing empirical evidence lending support to the existence of an "upper body strategy" to extend the ankle and hip strategies in maintaining upright postural stability among adults. Both postural stability and arm movement functions are still developing in children. Therefore, enquiry concerning arm contribution to postural stability among children is needed.

Predictors of Physical Activity for Preschool Children With and Without Disabilities From Socioeconomically Disadvantaged Settings.

The purpose of this study was to examine differences in motor competence, perceived motor competence (PMC), body mass index, and physical activity (PA) and to assess factors that predict PA behaviors of preschool children with and without disabilities. A total of 59 children with (n = 28) and without (n = 31) disabilities participated in the study. Results revealed that children with disabilities had significantly greater amounts of PA than peers without disabilities.

Correlates of physical activity among children with visual impairments.

Background: Children with visual impairments (VI) often reveal higher levels of sedentary time and lower levels of fundamental motor skills (FMS), health-related fitness (HRF) and physical activity (PA) than peers without visual impairments. Extrapolating correlates of HRF and PA are important to develop targeted intervention strategies aimed at improving health- and movement-based outcomes.

Objective: The purpose of this study was to examine associations among FMS (divided into locomotor and object control skills), HRF, and home- and sport-camp based PA measures in children with VI.

Head, Toes, Knees, SKIP! Improving Preschool Children's Executive Function Through a Motor Competence Intervention.

Executive function skills play a critical role in school readiness for young children and can be improved through targeted intervention. However, children in preschool often experience deficits in multiple developmental domains. Thus, there is a need for integrated interventions that target multiple domains in concert.
