Validity and Reliability of Applications in Predicting Vertical jump Ability in Adults

Abstract

Vertical jump is an individual's ability to jump vertically and reflects the explosive power of the leg muscles in adults. Measuring vertical jump using a force platform or vertec is costly and requires limited access. Technological developments have led to the creation of digital applications that provide a more practical method of measuring vertical jump in the field. This study aims to assess the scientific evidence related to the validity and reliability of various vertical jump measurement applications. A literature search was conducted through PubMed, ScienceDirect, and Google Scholar using keywords that combined the terms validity, reliability, vertical jump test, and application. The initial search yielded 822 articles, which were then selected based on inclusion criteria consisting of free full-text articles, publication years 2023-2025, adult subjects, and assessment of the validity or reliability of the application. The selection process resulted in 10 articles being analyzed. The findings showed that My Jump 2, GoJump, FTM (JumpEye), and DeepSport consistently had high validity and reliability, with My Jump 2 being the most stable application across various populations and conditions. The Jump Power application was considered reliable but not valid. Some applications were only accurate for jump height and not for variables such as force, speed, or power. This study concluded that applications with strong evidence of validity and reliability are suitable for use as practical alternatives in vertical jump evaluation, so the selection of tools should consider the measurement objectives and the quality of scientific evidence
