Twenty-seven male and female physical education students (23.5 \u00b1 3.8 years; height 170 \u00b1 9.1 cm and body mass 69.1 \u00b1 11.4 kg) performed three countermovement jumps simultaneously measured using five devices. The 3D measured displacement obtained through the Qualisys device was considered in this study as the reference value. The best accuracy (difference from 3D measured displacement) and precision (standard deviation of differences) for countermovement jump measurement was found using the Abalakow jump belt (0.8 \u00b1 14.7 mm); followed by the Force platform when employing a double integration method (1.5 \u00b1 13.9 mm) and a flight-time method employed using Qualisys motion system data (6.1 \u00b1 17.1 mm). The least accuracy was obtained for the Ergojump (\u221272.9 mm) employing its analytical tools and then for the accelerometer and Force platform using flight time approximations (\u221252.8 mm and \u221245.3 mm, respectively). The worst precision (\u00b1122.7 mm) was obtained through double integration of accelerometer acceleration data. This study demonstrated that jump height measurement accuracy is both device and analytical-approach-dependent and that accuracy and precision in jump height measurement are achievable with simple, inexpensive equipment such as the Abalakow jump belt.<\/jats:p>","DOI":"10.3390\/app12010511","type":"journal-article","created":{"date-parts":[[2022,1,5]],"date-time":"2022-01-05T20:42:16Z","timestamp":1641415336000},"page":"511","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["An Evaluation of the Accuracy and Precision of Jump Height Measurements Using Different Technologies and Analytical Methods"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1636-2685","authenticated-orcid":false,"given":"Filipe","family":"Concei\u00e7\u00e3o","sequence":"first","affiliation":[{"name":"Centre of Research, Education, Innovation and Intervention in Sport (CIFI2D), Faculty of Sport, University of Porto, Rua Dr. Pl\u00e1cido da Costa 91, 4200-450 Porto, Portugal"},{"name":"Porto Biomechanics Laboratory, University of Porto, 4200-450 Porto, Portugal"}]},{"given":"Martin","family":"Lewis","sequence":"additional","affiliation":[{"name":"Kurio 3D Compression LTD, Nottinghamshire NG18 5BR, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9344-8503","authenticated-orcid":false,"given":"Hern\u00e2ni","family":"Lopes","sequence":"additional","affiliation":[{"name":"Mechanical Engineering Department, School of Engineering, Polytechnic Institute of Porto, Rua Dr. Roberto Frias, 712, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1854-6514","authenticated-orcid":false,"given":"Elza M.
