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

Reproducibility and safety of the incremental shuttle walking test for cardiac rehabilitation
TL;DR: The Bland Altman limits of agreement method was used on 353 paired ISWTs to explore whether the recommended practice test is necessary, confirming the need for the practice walk when undertaking the ISWT.

Validity of a total body recumbent stepper exercise test to assess cardiorespiratory fitness.
TL;DR: Preliminary data suggest that the TBRS-XT may be a valid test to predict &OV0312;o2max when treadmill testing is not feasible, and this would allow clinicians an alternative method for exercise testing and prescription to promote healthy lifestyle interventions for a variety of patient populations.

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.
