Researchers and practitioners have highlighted the necessity to monitor jump strategy
metrics and the commonly reported outcome measures during the countermovement jump …

The purpose of this investigation was to analyse the concurrent validity and reliability of an
iPhone app (called: My Jump) for measuring vertical jump performance. Twenty …

BACKGROUND: To determine the reliability of squatting jumps (SJ), counter-movement
jumps (CMJ) and drop jumps (DJ) tests, as well as the reliability of the optimal dropping …

Vertical-jump tests are commonly used to evaluate lower-limb power of athletes and
nonathletes. Several types of equipment are available for this purpose. Purpose: To …

The aim of this study was to validate a wearable inertial measurement unit (IMU), containing
a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The …
