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

Identical pattern of cerebral hypoperfusion during different types of syncope
TL;DR: In the venular and mixed groups, comparable orthostatic tolerance and declines in BP, end-tidal PCO2, MCAv and cerebral oxygenation were evident despite distinct mechanisms purportedly being responsible for the hypotension.

TL;DR: In conclusion, the on-demand treadmill system provided a reliable measure of distance running performance and the vLT and vMLSS were strong predictors of 2-mile running performance, with v MLSS explaining marginally more of the variance.

Factors influencing bilateral deficit and inter-limb asymmetry of maximal and explosive strength: motor task, outcome measure and muscle group.
TL;DR: Compared to MVC torque and bilateral tasks, RTD measures and unilateral tasks could be considered more sensitive for the assessment of bilateral deficits and inter-limb asymmetries in healthy professional/semi-professional athletes.

TL;DR: The proposed CODS and RAG tests that involved dribbling over a 3.2-m distance appeared to be reliable, as well as valid for distinguishing the performance level in futsal players.

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.
