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

TL;DR: The results suggest that the MVN BIOMECH system can be used by a clinician to quantify lower-limb joint angles in clinically relevant movements.

Reliability of shoulder range of motion comparing a goniometer to a digital level.
TL;DR: A digital level can be used to reliably measure shoulder ROM but should not be used interchangeably with a standard goniometers, because glenohumeral rotation was 3–5° greater for the digital level than the goniometer (systematic error).

Automated metabolic gas analysis systems: a review.
TL;DR: Further knowledge about the performance characteristics of these systems is needed to aid physicians and scientists to select a system that is best suited to their requirements and may also improve the quality of these frequently reported physiological measures.

Reliability of time-to-exhaustion versus time-trial running tests in runners
TL;DR: Evaluating the reliability of comparable TTE and TT treadmill running tests of high and moderately high exercise intensity in endurance-trained male distance runners found log-log modeling using the TTE test results reliably predicted actual TT performance.

A protocol for classifying normal- and flat-arched foot posture for research studies using clinical and radiographic measurements
TL;DR: This foot screening protocol provides a coherent strategy for researchers planning to recruit participants with normal- and flat-arched feet and determines whether foot posture variations in the sagittal, transverse or both planes provide the best descriptor of the flat foot.

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.
