The validity and reliability of a portable device (ADR-Jumping) to estimate vertical jump performance

This study aimed to evaluate the relative, absolute reliability, and concurrent validity of the ADR-Jumping system. Fifty-two participants performed three countermovement jumps (CMJ) and three squat jumps (SJ) with a 1-week interval for test and retest reliability; Chronojump contact-mat was used while simultaneously measuring with the ADR-Jumping system for validity. Very strong correlations were observed between both devices for all types of jumps (CMJ: r = 0.98, p = 0.01; SJ: r = 0.97, p = 0.01). Regardless of the jump modality (CMJ and SJ), greater jumping heights were observed for ADR-Jumping compared to Chronojump, but these were trivial differences. Test-retest reliability was high (ICC = 0.89) for CMJ, and very high for SJ (ICC = 0.91). Absolute reliability was excellent for CMJ and SJ, with SEM and MDC percentage values of 2.99% and 4.77% for CMJ, and 2.71% and 4.11% for SJ, respectively. The ADR-Jumping is a valid, reliable, and useful tool for measuring jump height.
