Description / Abstract

The purpose of this study was to test the concurrent validity and intraclass reliability of two mobile apps designed to measure countermovement jump (CMJ) height. The concurrent validity and reliability of two mobile applications (MyJump2 and What'smyvertical) designed to measure vertical jump heights were analyzed using a force platform and 3D motion analysis as criterion methods. Twenty-two healthy, adult participants (female: n=15; male: n=7; ages: 18-26; height 1.74 m, mass: 69.7 kg) performed ten CMJs with instructions to jump as high as possible on a force platform with their hands on their hips, maintaining extended legs during flight. Both the MyJump2 and What'smyvertical apps exhibited strong agreement with COM displacement measured by 3D motion capture system with ICCs of 0.960 (95% CI: 0.143-0.991, p < 0.001) and 0.887 (95% CI: .177-0.970, p < 0.001), respectively. The results showed that jump height can accurately and reliably be estimated using these mobile applications, providing a valid and feasible tool in evaluating jump performance.
