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: Objective methods of muscle function assessment are critically analysed with specific attention to the issues of applicability, validity and reliability, and optimal procedures have yet to be identified.

TL;DR: It is demonstrated that the agility T-test and the aerobic Yo-Yo 10 m recovery test are reliable; consequently they may be appropriate instruments for measuring physical fitness in WB.

Test-retest reliability of knee kinesthesia in healthy adults
TL;DR: Assessment of test-retest reliability of a device designed to measure knee proprioception revealed that small changes in an individual's performance cannot be detected, and it is recommended that the TDPM be measured with a 20-degree starting position.

Quantitative somatosensory testing of warm and heat-pain thresholds: the effect of body region and testing method.
TL;DR: The sensitivity to noxious heat is uniform across the body when measured with a reaction-time-free method (Method of Limits), but is greater in proximal than in distal regions, when Measurement of Levels finds that the Method of Levels is preferred when heat-pain threshold is to be compared between body regions.

The effectiveness of hand cooling at reducing exercise-induced hyperthermia and improving distance-race performance in wheelchair and able-bodied athletes.
TL;DR: In this paper, the authors examined the effectiveness of reducing core temperature in post-exercise hyperthermic subjects and assessed if hand cooling (HC) improves subsequent timed distance in timed distance walking.

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.
