Background: Children with intellectual disability are less physically active and more sedentary than typically developing peers. To date no studies have tested the feasibility of a school-based walking intervention for children with Intellectual Disability. Method: A clustered randomised controlled trial (cRCT), with an embedded process…

Motor competence is important for lifelong physical activity (PA). The current study aimed to examine associations between PA and motor competence. In total, 43 children aged 7--12 years with intellectual disabilities and/or autism spectrum disorder completed anthropometric measures, the Bruininks-Oseretsky Test of Motor Proficiency-2, and wore a…

In this study, it was aimed to examine the effects of static and dynamic core exercises applied to football players aged 10-12 years on some physical fitness characteristics. The mean age of 12,4±0,4 years, average body weight of 43,2±0.31 kg, average height of 153,5±0.32 cm and average age of 4.32 years in sports, 32 male football players who…

Outdoor recreation has many benefits for youth. Benefits may be more profound in youth with visual impairments as the involvement in outdoor recreation activities provides improved self-determination and socialization. The purpose of this qualitative phenomenological study was to comprehend each participant's lived outdoor recreation experiences,…

Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

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…

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…

Background: The COVID-19 pandemic imposed social isolation measures, which impacted the child population, especially regarding physical and mental health aspects. Purpose The aim of this study was to investigate the relationship between sedentary behavior, cardiorespiratory fitness, immunoglobulin -A secretion, and anxiety symptoms in 267 children…

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…

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)…

It is aimed in this study to analyze the effects of the Montessori education method on children with Down syndrome and autism having special training who have received and not received Montessori education through the Eurofit test batteries selected for motor skills and physical fitness. A total of 20 male children with Down syndrome and autism in…

The purpose of this study was to examine the moderating role of adaptive behavior on the pathways connecting motor competence, physical activity, and health-related fitness in 7-12 year old children with ASD (N = 27). Results demonstrate that motor competence and health-related fitness were positively related (r = 0.42, p < 0.05), and this…

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 purpose of this study is to explore the effect of balance and stability workouts on the development of static and dynamic balance in 10-12-year-old soccer players. The sample of the study was 40 soccer players (n=20 control and n=20 experimental) aged 10-12 years (age=11.2±08). Besides daily training program, soccer players in the experimental…

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…
