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

Developing a New Method for Team Match Performance Analysis in Professional Soccer and Testing its Reliability
TL;DR: In this article, a new method for analysis of team match performance in soccer and test its reliability from videotapes was developed by using 22 multidimensional categorical variables, including qualitative evaluation of different dimensions of match performance involved in the opponent interaction.

Mechanical Player Load™ using trunk-mounted accelerometry in football: Is it a reliable, task- and player-specific observation?
Paulo Barreira,Mark A. Robinson,Barry Drust,Niels Jensby Nedergaard,Raja Mohammed Firhad Raja Azidin,Jos Vanrenterghem +5 more
TL;DR: It was concluded that monitoring PL® in football multidirectional actions presents moderate-to-high reliability, that between-participant variability most likely relies on the individual’s locomotive skills and not their anthropometrics, and that the intensity of a task expressed by PL · min–1 is largely related to the running velocity of the task.

Pilates-based exercise for persistent, non-specific low back pain and associated functional disability: A meta-analysis with meta-regression
TL;DR: Regression analysis was applied to randomised controlled trials that evaluated the effectiveness of Pilates exercise in improving persistent, non-specific low back pain and functional disability and found Pilates provided moderate to superior pain relief compared to MI.

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.
