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

The long-term development of volleyball game play performance using Sport Education and the Step-Game-Approach model:
TL;DR: In this article, a study was conducted to analyse 18 Portuguese high school students' game play performance improvements across three hybrid sport education-step-game-approach volleyball seasons, and the results showed that students' performance was significantly improved.

Point-of-care devices for physiological measurements in field conditions. A smorgasbord of instruments and validation procedures.
TL;DR: This review presents an account of physiological parameters that can be monitored with POC devices and surveys the literature for suitable quantitative and statistical procedures for comparing POC measurements with reference "gold standard" procedures.

Reliability of force-platform measures of postural sway and expertise-related differences.
TL;DR: Investigation of the skill-related differences between athletes and nonathletes in reliability of center-of-pressure summary measures under eyes-open (EO) and eyes-closed (EC) conditions found higher ICCs were found for COP measures in the athlete group, postfatigued condition, and EC tests.

Validity and reliability of the look Keo power pedal system for measuring power output during incremental and repeated sprint cycling.
TL;DR: The power data from the Keo power pedals should be treated with some caution given the presence of mean differences between them and the SRM, exacerbated by poorer reliability than that of theSRM power meter.

An intra- and interrater reliability and agreement study of vaginal resting pressure, pelvic floor muscle strength, and muscular endurance using a manometer
TL;DR: Manometry (Camtech AS) seems less accurate for the strongest women and in clinical practice, significant improvement in PFM variables needs to exceed the minimal detectable change to be above the error of measurement.

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.
