Engagement in physical activity plays a central role in the prevention and treatment of childhood overweight/obesity. However, some children may lack the skills and confidence to be physically active. This 3-year follow-up study aimed to form profiles based on cardiorespiratory fitness, actual motor competence, perceived motor competence, physical…

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…

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…

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…

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…

The aim of this study is to investigate motor performance of children by age and gender. A total of 160 children (80 girls and 80 boys) participated in this study voluntarily. Children were divided into 4 groups according to their gender (girls and boys) and age (11 and 12 years). One Way ANOVA and LSD tests were used. There were statistically…

In this study, it is aimed to review the effects of 8 week plyometric exercises on certain physiological parameters and freestyle swimming performance of swimmers of age 10-11 who practice swimming with a licence in city of Van. Study group has been created by 24 male volunteer swimmers who practice swimming with a licence in city of Van. 24…

Body dissatisfaction (BD) is a common experience among preadolescent girls and a robust risk factor and precursor to eating pathology (EP). Although the relationship between BD and EP has been well documented, there is less research exploring the factors that may make this relationship more or less pronounced. In the current study, we investigated…

In the present study, the purpose was to examine the effects of some physical characteristics on the stroke speed in forehand and backhand techniques in tennis. The Study Group consisted of 10-12-year-old tennis players of Isparta Süleyman Demirel University Tennis Courts (mean age 10.15±0.37 (years), mean height 1.46±0.06 (m) mean body weight…
