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 MARS for Squat, Countermovement, and Standing Long Jump Performance Analyses: Are Measures Reproducible?
TL;DR: Most of the jump test parameters from the MARS can be used with confidence to quantify changes in the functional ability of individuals over time, except for those relating to the rate of force development or change in momentum during countermovement phases of jumps.

Reproducibility and concurrent validity of hip joint angle test for estimating hamstring flexibility in recreationally active young men.
TL;DR: It is concluded that the test-retest reproducibility of the H-HJA, V-H JA, and PSLR is acceptable and that the validity of H-hJA and V- HJA is moderate and the H -HJA cutoff scores should not be used for V- hJA for the detection of short hamstring muscles in young adults.

Intelligent computational model for classification of sub-Golgi protein using oversampling and fisher feature selection methods
TL;DR: An intelligent automatic recognition model is developed in order to enhance the true classification rate of sub-Golgi proteins and is anticipated that the proposed model will provide the foundation to pharmaceutical industry in drug design and research community to innovate new ideas in the area of computational biology and bioinformatics.

Anticipatory activity of vastus lateralis and vastus medialis obliquus occurs simultaneously in voluntary heel and toe raises
TL;DR: Findings indicate that when the CNS can predict that a movement will challenge the stability of the knee an anticipatory postural adjustment is initiated that co-activates the medial and lateral muscles that guide the movement of the patella in the femoral groove.

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.
