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…

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…

Children with autism spectrum disorder (ASD) who have problems such as inactivity and the lack of communication need interventions that enable them to participate in society just like their peers. The purpose of this study was to investigate 'I can have physical literacy' programme (ICPL) on physical literacy (PL) in children with ASD. This study…

This study aims to analyze the effects of 6-week core training on certain biomotor abilities for footballers in the pubertal period. Accordingly, 30 male footballers who attend football courses regularly participated in the study. Footballers were divided into two groups; 15 of them were assigned to the Core Training Group (CTG) (age: 9.73 years;…

In order to monitor training effects and physical developments in elite sports, it may be beneficial to perform anthropometric measurements and physical fitness tests regularly. In this study, the relationship between the anthropometric properties and physical fitness values of elite figure skating athletes were investigated. 21 elite athletes in…

Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4-17.9 years) completed testing during a single session. Each measure provided percent body fat (%BF), while the InBody 720 included fat-free mass (FFM). The validity was examined…

This paper explores how young ballet dancers' bodies are constructed and narrated through their desire to become performing ballet dancers. The schooling of the balletic body engages the young dancer in embodying the discipline of ballet and in developing a particular belief in a performing body. The embodied set of acquired dispositions that are…

This study analyzed the passing rates on five health-related fitness items on the Brockport Physical Fitness Test of youths aged 10-17 with visual impairments. It found that the youths had low passing rates on upper-body strength, cardiovascular endurance, and body composition. (Contains 2 tables.)

The amount of variation associated with the assessment of skinfolds of preadolescents was investigated because skinfold assessment is a component of the Health Related Physical Fitness Test. Results suggest skinfold measurements vary relatively little due to testers, instruments, or repeated trials. (Author/MT)
