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

Microcurrent therapy in the management of chronic tennis elbow
TL;DR: In this article, the effects of different MCT parameters on pain and function, grip strength, and sonographically graded tendon structure and hyperaemia were compared. But no significant differences were found in other outcomes.

Assessing a smartphone application to measure counter-movement jumps in recreational athletes
TL;DR: The use of counter-movement jumps as a measure of neuromuscular performance in athletes has become common in the sport setting as mentioned in this paper, but accurate methods of measuring jump parameters are often expensive, and they are often unreliable.

Reproducibility of velocity-dependent power: before and after lengthening contractions
TL;DR: The isotonic mode is highly reliable when testing velocity-dependent power of the ankle dorsiflexors at baseline and following fatiguing lengthening contractions, and measures of absolute reliability for maximal shortening velocity and peak power also yielded high reliability.

Reliability and Detecting Change Following Short-Term Creatine Supplementation: Comparison of Two-Component Body Composition Methods
TL;DR: It is concluded that between-day differences in FFM estimation were within acceptable limits, with the possible exception of ANTHRO, and all 5 body composition techniques provided similar measures of FFM change during acute Cr supplementation.

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.
