TLDR
In this article, the reliability of a linear position transducer when compared to a force plate through a counter-movement jump in female participants was evaluated in a test-retest setting.Abstract:
The current study aimed to assess the validity and test–retest reliability of a linear position transducer when compared to a force plate through a counter-movement jump in female participants. Twe...read more

TL;DR: All metrics from the MotusBASEBALL unit showed significant correlations to their corresponding metrics from motion capture and while some magnitudes differ substantially and therefore fall short in validity, the link between the metrics is strong enough to indicate reliable casual use.

The reliability and accuracy of Polar Team Pro GPS units
TL;DR: This study aimed to investigate the accuracy and reliability of Polar Team Pro GPS units (10 Hz) when used to measure distance and total distance covered in different speed zones.
Journal ArticleDOI
The Influence of Match-Day Napping in Elite Female Netball Athletes.
TL;DR: It is suggested that a short nap (<20 min) on the day of competition can enhance jump velocity and improve subjective performance in elite netball players, as assessed by coaching staff.
Journal ArticleDOI
Validity and Reliability of the GymAware Linear Position Transducer for Squat Jump and Counter-Movement Jump Height.
TL;DR: While the LPT overestimates jump height, it is a reliable tool for tracking changes in jump height to measure performance improvement and monitor fatigue.

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

Reliability and factorial validity of squat and countermovement jump tests.
TL;DR: It can be concluded that CMJ and SJ, measured by means of contact mat and digital timer, are the most reliable and valid field tests for the estimation of explosive power of the lower limbs in physically active men.
