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

Physiological assessment of aerobic training in soccer
TL;DR: This review presents some physiological laboratory-based tests and field tests used to evaluate training outcomes in soccer, together with methods based on heart rate and perceived exertion to quantify internal load imposed during training.

Reliability and validity of the combined heart rate and movement sensor actiheart
TL;DR: The Actiheart is technically reliable and valid but further studies are needed to assess validity in other activities and during free-living.

Validity, Reliability and Sensitivity of Measures of Sporting Performance
TL;DR: A sensitive protocol is one that is able to detect small, but important, changes in performance, and research has shown that time-to-exhaustion protocols are more reliable as they have been shown to have a CV of <5%.
ORIGINAL COMMUNICATION Reliability and validity of the combined heart rate and movement sensor Actiheart
TL;DR: The Actiheart as discussed by the authors is a combined heart rate (HR) and movement sensor, which is designed to assess physical activity in populations and has been shown to be reliable and valid for walking and running.

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.
