Physical load data were obtained by manually logging all physical activities and using wearable sensors. Daily wellness of players was monitored using questionnaires. Match performance was derived from annotated actions by a video scout during matches. We identified conditions of predictor variables that related to attack and pass performance (p &lt; 0.05). Better attack performance is related to heavy weights of lower-body strength training exercises in the preceding four weeks. However, worse attack performance is linked to large variations in weights of full-body strength training exercises, excessively heavy upper-body strength training, low jump heights and small variations in the number of high jumps in the four weeks prior to competition. Lower passing performance was associated with small variations in the number of high jumps in the preceding week and an excessive amount of high jumps performed, on average, in the two weeks prior to competition. Differences in findings with respect to passing and attack performance suggest that elite volleyball players can improve their performance if training schedules are adapted to the position of a player.<\/jats:p>","DOI":"10.3390\/s22207996","type":"journal-article","created":{"date-parts":[[2022,10,21]],"date-time":"2022-10-21T00:34:30Z","timestamp":1666312470000},"page":"7996","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Modeling Match Performance in Elite Volleyball Players: Importance of Jump Load and Strength Training Characteristics"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9857-0970","authenticated-orcid":false,"given":"Arie-Willem","family":"de Leeuw","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Antwerp\u2014IMEC, 2000 Antwerp, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rick","family":"van Baar","sequence":"additional","affiliation":[{"name":"The Dutch Volleyball Federation (Nevobo), 3528 BE Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0335-5099","authenticated-orcid":false,"given":"Arno","family":"Knobbe","sequence":"additional","affiliation":[{"name":"Leiden Institute of Advanced Computer Science (LIACS), Leiden University, 2333 CA Leiden, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8296-828X","authenticated-orcid":false,"given":"Stephan","family":"van der Zwaard","sequence":"additional","affiliation":[{"name":"Leiden Institute of Advanced Computer Science (LIACS), Leiden University, 2333 CA Leiden, The Netherlands"},{"name":"Department of Human Movement Sciences, Faculty of Behavioral and Movement Sciences, Amsterdam Movement Sciences, Vrije Universiteit Amsterdam, 1081 BT Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,20]]},"reference":[{"key":"ref_1","first-page":"35","article-title":"Match Analysis in Volleyball: A systematic review","volume":"5","author":"Silva","year":"2016","journal-title":"Montenegrin J.
