The purpose of the present study was (i) to explore the reliability of the most commonly used
countermovement jump (CMJ) metrics, and (ii) to reduce a large pool of metrics with …

Purpose: Dozens of variables can be derived from the countermovement jump (CMJ).
However, this does not guarantee an increase in useful information because many of the …

The countermovement jump (CMJ) is often used as performance measure and monitoring
tool. Traditionally, jump height (JH) is most often studied and reported, but other variables …

Countermovement jumps (CMJs) are widely used in athlete training, performance
monitoring and research as an indicator of power output. Despite extensive scientific …

Different thresholds have been used to determine the start of the force-time analysis during
countermovement jump testing. This study examined the influence of the jump starting …

This study aimed to investigate the contributions of kinetic and kinematic parameters to inter-
individual variation in countermovement jump (CMJ) performance. Two-dimensional …

The aim of this study was to analyze the concurrent validity, test–retest reliability, and
capacity to detect changes of four different portable devices used to measure a wide range …

Previous research has demonstrated large amounts of inter-subject variability in downward
(unweighting & braking) phase strategies in the countermovement jump (CMJ). The purpose …

This study explored the influence of different take-off thresholds on the reliability and
magnitude of countermovement jump (CMJ) performance variables. Twenty-three men were …
