This study aimed to assess the validity of WIMU PRO&lt;sup&gt;TM&lt;\/sup&gt; devices for jump detection in beach volleyball and to determine, in a preliminary way, whether gender, the player's individuality or the technical action associated with the jump could influence data accuracy. Eleven beach volleyball players (6 female and 5 male) were recorded with high-definition cameras and the WIMU PRO&lt;sup&gt;TM&lt;\/sup&gt; device during 42 one-set official matches. The number of jumps recorded by the device was compared with the observational analysis. The instrument's sensitivity was calculated based on true positives and false positives\/negatives in terms of gender, player individuality, and the type of the jump. The WIMU PRO&lt;sup&gt;TM&lt;\/sup&gt; device presented great sensitivity (96.29%), with a lower gender difference (male = 97.20%, female = 94.56%) and higher inter-player variability in females (91.06%\u201398.08%) than males (95.02%\u201398.40%). Regarding the type of the jump, actions classified as \u201cOthers\u201d (99.10 %) obtained the greatest sensitivity, followed by \u201cBlock\u201d (97.25 %), \u201cSpike\u201d (95.75 %) and \u201cServe\u201d (94.69 %). The WIMU PRO&lt;sup&gt;TM&lt;\/sup&gt; is a valid device for automatic jump detection in beach volleyball. The variations observed in terms of gender, players' individuality, and the type of the jump highlight the importance of a context-specific individualized algorithm adjustment.<\/jats:p>","DOI":"10.5114\/jhk\/196549","type":"journal-article","created":{"date-parts":[[2025,5,30]],"date-time":"2025-05-30T09:47:32Z","timestamp":1748598452000},"source":"Crossref","is-referenced-by-count":1,"title":["Validation of the WIMU PRO&lt;sup&gt;TM&lt;\/sup&gt; Device for Jump Detection in Beach Volleyball: A Gender-Based Analysis during Official Competitions"],"prefix":"10.5114","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2107-2025","authenticated-orcid":true,"given":"Joaqu\u00edn Mart\u00edn","family":"Marzano-Felisatti","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9091-0897","authenticated-orcid":false,"given":"Jose","family":"Pino-Ortega","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8210-4118","authenticated-orcid":false,"given":"Antonio","family":"Garcia-de-Alcaraz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6264-5520","authenticated-orcid":false,"given":"Javier","family":"Portillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2272-8217","authenticated-orcid":false,"given":"Jos\u00e9 Francisco","family":"Guzm\u00e1n-Luj\u00e1n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0375-1454","authenticated-orcid":true,"given":"Jose Ignacio","family":"Priego-Quesada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2025,5,29]]},"reference":[{"key":"ref-1447301","doi-asserted-by":"publisher","DOI":"10.2307\/2987937"},{"key":"ref-1447302","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2014-093593"},{"key":"ref-1447303","unstructured":"Batista, G.
