The agreement between a wearable inertial sensor (GYKO, G) and the force platform (P) was assessed by evaluating "test-retest" and "inter-rater reliability." Thirty-eight subjects were enrolled; the selected indices of balance were investigated over foot positions and (un)stable conditions. Intraclass correlation coefficient…

Between limb strength, asymmetry is a leading risk factor for hamstring strain re-injury. However, few accurate testing methodologies are available in clinical settings. This study examined the validity and reliability of eccentric knee flexor torque measured with a novel Nordic Hamstring Device. Twenty-seven healthy participants were assessed in…

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,…

Our aim in this study was to analyze associations between the two manipulative tests of the Motor Competence Assessment (MCA) battery and the Wall Drop Punt Kick & Catch (WDPK&C) motor task. One hundred and twelve early adolescents (60 boys; 52 girls; M age = 12.67, SD = 1.78 years) participated. Overall, strong correlations were found…

Small sample sizes contribute to several problems in research and knowledge advancement. This conceptual replication study confirmed and extended the inflation of type II errors and confidence intervals in correlation analyses of small sample sizes common in kinesiology/exercise science. Current population data (N = 18, 230, & 464) on four…

As part of a validation study of the Exercise Planning and Scheduling (EPS), and Goal-Setting (EGS) Scales, which were translated from English to Brazilian Portuguese, we aim to: present evidence of reliability and validity for the translated scale; and, explore the effects of non-labeled response categories of rating scales. The sample comprised…

Several observation tools evaluate teaching quality in Physical Education (PE), but none of them cover the core competencies required to comprehensively assess whether the teacher is providing teaching quality in PE. The aim of this research is to develop, validate, and test the reliability of the System for Observing Teaching Competencies in…

Relative adiposity (%Fat) was measured using a smartphone-based application in a convenience sample of adults aged 20-52 years (n = 32, 68.7% female, 84.3% White/Caucasian, 26.7 ± 3.5 kg/m2) across different body positions (Anterior versus Posterior) on consecutive days (Day 1 versus Day 2). A reference photo was obtained from the posterior view…

This study evaluated the reliability and construct validity of the 51-item Effective Early Childhood Physical Literacy Pedagogue self-report instrument (ECE-PLP) measuring Early Childhood Educators' (ECEs) perceived physical literacy (PPL) capabilities, knowledge, and practices for effectively promoting PL in young children. 494 ECEs completed the…

Constraints-led approach (CLA) is widely used in physical education (PE). This four-phased study aimed to develop a self-report measurement of students' perceived constraints support in PE. The relationships among students' perceived constraints support, competence and novelty need satisfaction, motivation, effort, and engagement in PE were also…
