Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine
Greg Atkinson,Alan M. Nevill +1 more
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

Examination of the validity and reliability of the accusport blood lactate analyser
Hugh Pinnington,Brian Dawson +1 more
TL;DR: A need exists to develop specifically generated regressions from Accusport and Analox LM3 analyser measures to provide more accurate results when interpreting lactate values fromaccusport measures taken in the field.

Reproducibility of proximal and distal transcutaneous oxygen pressure measurements during exercise in stage 2 arterial claudication.
P. Bouye,Jean Picquet,Vincent Jaquinandi,Bernard Enon,Georges Leftheriotis,Jean-Louis Saumet,Pierre Abraham +6 more
TL;DR: TcpO2 measurement on the calf or buttock during exercise, is a reproducible measurement in patients with vascular claudication, specifically when corrected for exercise-induced systemic pO2 changes trough Delta-from-rest of oxygen pressure calculation.

Assessing the efficacy of exercise training in patients with chronic disease.
TL;DR: Although conventional statistical analyses indicate that exercise training favorably alters .VO(2peak) and oxygen uptake kinetics of patients with ESRD, it is apparent that considerable interindividual variability exists in the response to training.

Test-retest reliability and minimal clinical change determination for 3-dimensional tibial and femoral accelerations during treadmill walking in knee osteoarthritis patients.
Katia Turcot,Rachid Aissaoui,Rachid Aissaoui,K. Boivin,K. Boivin,Nicola Hagemeister,Nicola Hagemeister,M. Pelletier,Jacques A. de Guise,Jacques A. de Guise +9 more
TL;DR: The proposed method is the first to have determined the reliability and the minimal detectable change for tibial and femoral acceleration parameters in knee OA patients during a treadmill walking evaluation.
Journal Article
Familiarisation and reliability of sprint test indices during laboratory and field assessment.
TL;DR: The results indicate that reliable data can be derived from single maximal sprint measures in both indoor and outdoor environments using fixed distance protocols, however, significant differences in time/speed over 20-m exist between field and laboratory conditions.

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.
