The study aimed to analyze, synthesize, and investigate the measurement properties of clinical tests that assess foot posture in children and adolescents. The study included research published in scientific journals that analyzed the measurement properties of clinical tests, focusing on the validity, reliability, responsiveness, or specificity of…

The aim of this study is to examine the available scientific evidence on the reliability and criterion validity of 6-minute run walk field-based test when administered to children and adolescents. Systematic searches were performed in three electronic databases (MEDLINE/PubMed, SPORTDiscuss and Scopus) from their inception until February 2024,…

The purpose of our study was to assess the test-retest reliability and concurrent validity of the 30 sec Sit to Stand test in a sample of adolescents. We recruited 30 male (58%) and 22 female (42%) participants (mean age = 15.77 years ± 0.46). Participants completed the 30-sec Sit to Stand and standing long jump tests on two occasions separated by…

The objective of the present research is to examine the factor structure of the Interpersonal Behavior Questionnaire (IBQ) and the Interpersonal Behavior Self Questionnaire (IBQ-Self) in the sport context. Confirmatory factor analyses were used to assess the psychometric properties and measurement invariance across sex and sports. For the IBQ, a…

In 2011, the National Collaborative on Childhood Obesity Research established a Measures Registry (updated in 2020) for four key variables associated with childhood obesity. We analyzed the individual physical activity behaviors portion of the Measures Registry to highlight strengths and gaps in the reliability and validity literature for…

This study aimed to translate the modified Group Environment Questionnaire (GEQ) and the Youth Sport Environment Questionnaire (YSEQ) into Norwegian, examine the factor structure and reliability of the scales through independent clusters model confirmatory factor analysis (ICM-CFA) and exploratory structural equation modeling (ESEM), and examine…

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…

This study aimed to assess the validity and reliability of jump assessments using the "MyJump2" application. Eleven junior athletes (15 ± 1.4 years) performed five countermovement (CMJ) and drop jumps (DJ) measured simultaneously by a force platform and "MyJump2." Additionally, intra- and inter-day reliability was assessed over…

Fundamental movement skills (FMS) competence is low in adolescent girls. An assessment tool for teachers is needed to monitor FMS in this demographic. The present study explored whether the Canadian Agility and Movement Skill Assessment (CAMSA) is feasible for use by physical education (PE) teachers of Australian Year 7 girls in a school setting.…

This study presents the development process and initial validation of the NyTid test, a process-oriented movement assessment tool for compulsory school pupils. A sample of 1,260 (627 girls and 633 boys; mean age of 14.39) Swedish school children participated in the study. In the first step, exploratory factor analyses (EFAs) were performed in…

In this study the authors examine the test-retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power and was validated with 3 anaerobic lab tests: (a) vertical jump, (b) the Margaria-Kalamen stair test, and (c) the Wingate Anaerobic Test. The…
