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…

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 purpose was to evaluate reliability of measurements during drop jump (DJ) and magnitude of differences in vertical jump height (VJH) when calculated using two variables: time-in-the-air and center-of-mass velocity. Thirty-seven handball players performed three single-leg and double-leg DJs on a portable force plate during two sessions. Sixteen…

The aim of the study was to investigate the reliability and validity of the timed up & go (TUG) test and the 30-s sit-to-stand (30-s STS) test performed via tele-assessment in ambulatory patients with stroke. Sixty-one patients with chronic stroke were included. For reliability, test-retest and inter-rater reliability were determined. For…

Spinal alignment can be assessed without radiation using three-dimensional ultrasound imaging (3DUS). Reliable measurements could inform the ideal arm position for scoliosis radiographs. This study determined the inter-evaluator reliability of axial vertebral rotation (AVR) measurements and sagittal curve angles in healthy females from 3DUS spinal…

This study aimed to develop and test MyPL, a questionnaire that measures self-reported physical literacy (PL) among children and adolescents. First, the item pool was developed and adapted, and face validity was tested with cognitive interviewing. Then, factor structures were identified through multidimensional scaling and exploratory factor…

This study aimed to review the validity and/or reliability of light-intensity physical activity (LPA) questionnaires and identify the most suitable questionnaires for measurement of LPA in adults. Following the PRISMA-P 2020 guidelines, we searched MEDLINE, PsycINFO, CINAHL, Scopus, Embase, and MedNar. Only studies that targeted adults [greater…

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…

The present study aimed to validate the Chinese version of the Tendency to Avoid Physical Activity and Sport Scale (TAPAS) among university students living in Hong Kong to assess weight and body image concerns. A convenience sample of 787 students (63.5% females; 24.5% overweight) were recruited online. The factor structure of the scale was…

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…

This study investigated the objectivity, reliability, and the validity of the Basketball Throw Test (BTT) as an upper-body muscular strength measure. Participants (33 boys and 32 girls; mean age = 8.75 ± 1.47) performed the BTT on 2 occasions (1-week apart), and the hand-grip test as criterion measure. The objectivity and reliability were…

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…

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…

The present study sought to examine the psychometric properties of new German, Portuguese, and Spanish versions of the Revised Short Form of the Physical Self-Inventory (PSI-S-"R"), and to contrast these properties against those from the original French version of this instrument. Participants (n = 1802) were 288 French youth, 177 German…

Mindfulness is growing in popularity with the potential to improve many favorable health outcomes. Physical activity (PA) is crucial for improving health, however, there is no Turkish scale to measure mindfulness during PA. The purpose of this study was to translate, culturally adapt, and validate the Turkish version of The State Mindfulness Scale…
