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

Anthropometric characteristics and motor skills in talent selection and development in indoor soccer.
TL;DR: Anthropometric characteristics and physical capacities do not necessarily differentiate players at post-pubertal stages and should not be overvalued during early development and considering the coaches' rankings, performance measures outside the specific game conditions may not be useful in identification of talented players.

Variability in performance on a work simulation test of physical fitness for firefighters.
TL;DR: The results indicate the importance of practice on performance and the potential for false-positive or false-negative decision errors if biological variability is not taken into account.

Reliability of goniometric and trigonometric techniques for measuring hip-extension range of motion using the modified Thomas test.
TL;DR: Using the TRIG technique to measure hip-extension range of motion during the modified Thomas test results in superior intrarater and interrater reliability when compared with the GON technique.

Mechanically braked Wingate powers: agreement between SRM, corrected and conventional methods of measurement.
TL;DR: The results suggest that these three measures of power are similar when sampled over 30’s, but discrepancies occur when the sample time is reduced to either 1 or 5 s.

The Effect of Participation in Gaelic Football on the Development of Irish Professional Soccer Players
Paul R. Ford,A. Mark Williams +1 more
TL;DR: The participation profiles of two groups of professional soccer players in Ireland who either had or had not played Gaelic football to an elite level in adolescence provided support for the developmental model of sport participation (DMSP).

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.
