This study examined the relationship between the accuracy of parental reporting of children's sleep duration compared to objectively measured child sleep and tested whether any discrepancies were related to childhood obesity prevalence in a sample of Latinx families (N = 119). A paired sample t-test revealed that parents significantly…

Background: Fundamental Motor Skills (FMS) are important building blocks for children's sport-participation and lifelong physical activity. In the last decade, several international studies have reported delays in the development of FMS. To get better insight into the Dutch situation and to provide future directions, this study examined the…

We developed plank test standards, based on trunk lean mass-to-fat mass (LM/FM) ratio, in a sample of healthy Portuguese 10--18 year olds (n = 474, 46.4% female). Height and weight were measured and muscular endurance was assessed using the prone plank test. Trunk LM/FM ratio was determined using dual-energy x-ray absorptiometry. Plank standards…

We developed age- and sex-specific smoothed percentiles for vertical and long jump, as well as vertical jump power, in healthy 10-18 year olds (n = 529, 47.1% female). Jump height and distance were measured and vertical jump power was assessed via mechanography. LMS regression was used to create smoothed age-specific reference curves, separated by…

This study evaluated test-equating methods to enable comparisons and conversions between the vertical jump (VJ) and standing long jump (SLJ) tests. A total of 528 youth (280 males) performed VJ and SLJ, and their scores were randomly split as the calibration (C) sample (n = 478) and cross-validation (CV) sample (n = 50). SLJ scores of the C sample…

The primary aim of this study was to identify levels of fundamental movement skills (FMS) proficiency in primary school children. A secondary aim was to establish if these FMS proficiency levels differentiated between children born in different quartiles of the school year. The results demonstrated overall levels of FMS proficiency were low in…

The aim of the study is to examine the effects of core training in 9-10 years aged male handball players on selected biomotor and techniques special to the branch. This research is an experimental study in the screening model. The study consists of a total of 26 male volunteer students, including the experimental (n=13) and Control (N=13) group.…

Youth with Autism Spectrum Disorder (ASD) are at an increased risk for developing obesity when compared to their typically developing peers. Given higher prevalence of obesity in youth with ASD, understanding factors relating to success in obesity treatment provides insight into implementing efficacious treatments for youth. The current study…

Incorporation of the vertical jump (VJ) test in health-related fitness batteries is predicated on the availability of prediction equations to accurately estimate VJ power. The purpose was to develop and validate a generalizable equation to estimate VJ power from VJ height, body mass, age, and sex in 10- to 18-year-olds. The sample (N = 529)…

This study examined the predictive validity of musculoskeletal fitness tests for identifying sarcopenia in youth. The sample was 529 participants age 10 to 18 years. Indices included: total lean body mass (LBM) normalized for height (LBM index, LBMI, kg/m2), appendicular LBMI (aLBMI, kg/m[superscript 2]), and LBM to fat body mass (FBM) ratio…

The aim of this study was to determine what kind of performance characteristics distinguish between different skill levels at different development stages in field hockey using a multi-dimensional testing battery. A total of 100 players identified as "talented" (51.0% girls) and 105 recreational level players (41.0% girls) divided over…

Adolescence is a time of exceptional physical health juxtaposed against significant psychosocial and weight-related problems. The study included 241, 10-to-13-year-old youth with autism spectrum disorder (ASD, N = 138) or typical development (TD, N = 103). Standardized exams measured pubertal development, height (HT), weight (WT), heart rate (HR),…

The aim of this study is to investigate the effects of 8-week balance exercises on the speed and agility in 10-12 year-old children in physical education lessons. A total of 789 students participated in the study voluntarily. The students were randomly divided into two as experimental group (n=399) and control group (n=390). In addition to their…

The purpose of this study is to examine the effect of soccer activities on body composition and physical fitness among prepubertal boys. A total of 38 prepubescent male soccer players (mean age, 12.1±0.13 years) were compared with 41 participants in control group (mean age, 12.4±0.06 years). The body composition was measured using the…

Children's health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school…
