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

Assessing the limitations of the Banister model in monitoring training.
Philippe Hellard,Marta Avalos,Lucien Lacoste,Frédéric Barale,Jean-Claude Chatard,Grégoire P. Millet +5 more
TL;DR: The accuracy, the ill-conditioning and the stability of this model were investigated, and some parameters were highly correlated, making their interpretation worthless, and possible ways to deal with these problems are suggested.

TL;DR: In this paper, the authors focused on residents at senior citizens homes and their subjective view about the importance of various indicators concerning quality of life which are influenced by regular physical activity and found that physically active people attach great significance to surroundings as a dimension alongside all variables which are in connection with physical activity.

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.
