Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine

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

Reliability of physical functioning tests in patients with low back pain: a systematic review
Lenie Denteneer,Ulrike Van Daele,Steven Truijen,Willem De Hertogh,Jill Meirte,Gaetane Stassijns +5 more
TL;DR: None of the identified clinical tests could be concluded to have a good intrarater reliability, and further investigation should focus on a better overall study methodology and the use of identical protocols for the description of clinical tests.

The inter and intra-rater reliability of the Netball Movement Screening Tool
TL;DR: The Netball Movement Screening Tool may be a reliable screening tool for adolescent netball players; however the individual test scores have low reliability.

Reliability of three commercially available heart rate variability instruments using short-term (5-min) recordings.
TL;DR: To assess the reliability of heart rate variability measures made by three commercially available analysers in healthy subjects, a large number of subjects were randomly assigned to receive one of the three analysers.

The Role of Notational Analysis in Soccer Coaching
TL;DR: How notational analysis can influence the coaching process is discussed, giving examples predominantly taken from published literature related to soccer, using data collected via collaboration with a professional soccer team.

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.
