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

Test–retest reliability of Kinect’s measurements for the evaluation of upper body recovery of stroke patients
TL;DR: The results of this study show acceptable reliability and sensitivity across the sessions for MV, LJ and C measured by Kinect for both healthy subjects and stroke patients, which are promising for the development of home-based rehabilitation systems, which can analyze patient's movements using Kinect as an affordable motion capture sensor.

Reference values, intertest correlations, and test-retest repeatability of selected tear film tests in healthy cats.
TL;DR: Generally poor correlation among tests suggested that thorough tear film analysis requires performance of multiple tests in concert, and relatively poor test-retest repeatability should be considered when repeated tests are used to monitor tear film dysfunction and response to treatment.

TL;DR: The PUSH demonstrated good validity and reliability and was unable to provide a valid and reliable estimate of any other criterion variable in either exercise, but it may be more appropriate for athletes to jump off the ground with this load to optimize power output.

Assessing Muscle-Strength Asymmetry via a Unilateral-Stance Isometric Midthigh Pull
TL;DR: This study demonstrated high within-session reliability for unilateral-stance IMTP PF, revealing significant differences in isometric force-time characteristics between D and ND limbs in male athletes.

The Effect of Plyometric Training Volume on Athletic Performance in Prepubertal Male Soccer Players.
Helmi Chaabene,Yassine Negra +1 more
TL;DR: After 8 wk of training, results showed similar performance improvement on measures of sprint time, CoD, and jumping ability between LPT and HPT groups, and it is recommended to use LPT in prepubertal male soccer players to improve their proxies of athletic performance.

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.
