20.500.12556/RUL-133681 Concurrent validity and reliability of My Jump 2 app for measuring vertical jump height in recreationally active adults This study aimed to examine the reliability, validity, and usefulness of the smartphone-based application, My Jump 2, against Optojump in recreationally active adults. Participants (18 women, 28.9 ± 5.6 years, and 26 men, 30.1 ± 10.6 years) completed squat jumps (SJ), counter-movement jumps (CMJ), and CMJ with arm swing (CMJAS) on Optojump and were simultaneously recorded using My Jump 2. To evaluate concurrent validity, jump height, calculated from flight time attained from each device, was compared for each jump type. Test-retest reliability was determined by replicating data analysis of My Jump 2 recordings on two occasions separated by two weeks. High test-retest reliability (Intraclass correlation coefficient (ICC) > 0.93) was observed for all measures in both male and female athletes. Very large correlations were observed between the My Jump 2 app and Optojump for SJ (r = 0.95, p = 0.001), CMJ (r = 0.98, p = 0.001), and CMJAS (r = 0.98, p = 0.001) in male athletes. Similar results were obtained for female recreational athletes for all jumps (r > 0.94, p = 0.001). The study results suggest that My Jump 2 is a valid, reliable, and useful tool for measuring vertical jump in recreationally active adults. Therefore, due to its simplicity and practicality, it can be used by practitioners, coaches, and recreationally-active adults to measure vertical jump performance with a simple test as SJ, CMJ, and CMJAS. sport measurement healthy athletes jump performance smartphones My Jump 2 reliability validity šport meritve športniki zdravi športniki skok pametni telefoni My Jump 2 zanesljivost true false true Angleški jezik Slovenski jezik Članek v reviji 2021-12-08 15:19:10 2021-12-08 15:19:11 2022-09-13 03:52:03 0000-00-00 00:00:00 2020 0 0 11 str. iss. 11, art. 3805 Vol. 10 May 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.01 2076-3417 10.3390/app10113805 18302723 RAZ_Bogataj_Spela_2020.pdf RAZ_Bogataj_Spela_2020.pdf 1 9F112167814CEB67F6A1CD18FFEBA5C7 21e72f602aba313ac6dd63bc944aaeeb4334fc7bbb592a03637c5759f28b7afb 31222e35-5832-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151950 https://www.mdpi.com/2076-3417/10/11/3805 1 b56ab1af-5831-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151949 Fakulteta za šport 0 0 0
