Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine
Greg Atkinson,Alan M. Nevill +1 more
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

Agreement between the spatiotemporal gait parameters from two different wearable devices and high-speed video analysis

TL;DR: It is suggested that both foot pods are valid tools for measuring spatiotemporal parameters during running on a treadmill at comfortable velocity and if the limits of agreement of both systems are considered in respect to high-speed VA, the RunScribe seems to be a more accurate system for measuring temporal parameters and SL than the Stryd™ system.

Validity of auscultatory and penaz blood pressure measurements during profound heat stress alone and with an orthostatic challenge
TL;DR: Auscultatory SBP and Penaz SBP failed to track the decrease in intra-arterial SBP that occurred during the profound heat stress, while decreases in arterial BP during an orthostatic challenge are comparable between methodologies.

TL;DR: The reliability of the 6MWT in young children is demonstrated, its evolution with age is underscored, and it is indicated that a shorter version of the test is also reliable.

Interrater and Intrarater Reliability of the Beighton Score: A Systematic Review.
Lauren N. Bockhorn,Angelina M. Vera,David Dong,Domenica A. Delgado,Kevin E. Varner,Joshua D. Harris +5 more
TL;DR: The Beighton score is a highly reliable clinical tool that shows substantial to excellent inter- and intrarater reliability when used by raters of variable backgrounds and experience levels.
Journal ArticleDOI
Activity Profile and Between-Match Variation in Elite Male Field Hockey.
TL;DR: This is the first study to present an activity profile of elite men's field hockey and its associated variability and demonstrates that each position is unique, and therefore, training and recovery should be position specific.

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.
