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

Intra- and interrater reliability of the establishment of one repetition maximum on squat and seated knee extension.
Sofi Tagesson,Joanna Kvist +1 more
TL;DR: A systematic procedure for the establishment of 1 repetition maximum (1RM) is developed in order to describe an easily accessible test procedure that is applicable for physical therapists and athletic trainers who manage strength training for healthy individuals and patients.

Impact of Blood Flow Restriction Exercise on Muscle Fatigue Development and Recovery.
TL;DR: Despite the high level of muscle fatigue during BFR exercise, the effect of BFR on muscle fatigue was diminished after 2 min of reperfusion, suggesting that BFR has a strong but short-lasting effect on neuromuscular function.

Intensity and daily reliability of the six-minute walk test in moderate chronic heart failure patients.
TL;DR: Despite an intensity significantly lower but close to that of the symptom-limited exercise test, the 6MWT was well tolerated in both CHF groups and is reliable on a daily basis, for the distance walked.

Reliability of the Tuck Jump Injury Risk Screening Assessment in Elite Male Youth Soccer Players
TL;DR: Knee valgus may be reliably used to screen elite youth male soccer players for this plyometric technique error and for test-retest comparison, but caution should be applied in solely interpreting the composite score due to the high within-subject variation in a number of the individual criteria.
Journal ArticleDOI
Cross-cultural adaptation, reliability, and validity of the Japanese version of the Cumberland ankle instability tool.
TL;DR: The Japanese version of the CAIT has been shown to be a valid and reliable questionnaire for determining the presence of CAI and will be critically useful in assessment procedure for CAI.

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.
