TLDR
It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis.Abstract:
Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports physician to relate the described error to judgements regarding ‘analytical goals’ (the requirements of the measurement tool for effective practical use) rather than the statistical significance of any reliability indicators.read more

Nonlinear metrics assessing motor variability in a standardized pipetting task: between- and within-subject variance components
TL;DR: The reported data on between- and within-subject variability can be used to design future studies using nonlinear motor variability metrics on kinematics data.

Predicting vertical jump height from bar velocity
Amador García-Ramos,Igor Štirn,Paulino Padial,Javier Argüelles-Cienfuegos,Blanca de la Fuente,Vojko Strojnik,Belén Feriche +6 more
TL;DR: The results suggest that Vmax is a valid tool for estimating vertical jump height in a loaded jump squat test performed in a Smith machine and mean propulsive velocity recorded by a linear velocity transducer does not appear to be optimal to monitor ballistic exercise performance.

Reliability and Validity of the Early Years Physical Activity Questionnaire (EY-PAQ)
Daniel D. Bingham,Paul J. Collings,Stacy A. Clemes,Silvia Costa,Gillian Santorelli,Paula L. Griffiths,Sally E. Barber +6 more
TL;DR: The EY-PAQ has comparable validity and reliability to other PA self-report tools and is a promising population-based measure of young children’s habitual MVPA but not ST.

Do directed cough maneuvers improve cough effectiveness in the early period after open heart surgery? Effect of thoracic support and maximal inspiration on cough peak expiratory flow, cough expiratory volume, and thoracic pain.
TL;DR: Maximal inspiration increased CPEF and CEV, but the method of thoracic support used did not reduce pain during cough or influence the cough values the authors measured.

Statistical methods for assessing agreement between two methods of clinical measurement
TL;DR: In this article, an alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability, which is often used in clinical comparison of a new measurement technique with an established one.

A concordance correlation coefficient to evaluate reproducibility.
TL;DR: A new reproducibility index is developed and studied that is simple to use and possesses desirable properties and the statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation.
