Environmental data for each of these matches were obtained for dry-bulb and wet-bulb globe temperatures (WBGT) retrospectively from public sources. Linear regressions were used to determine relationships between running performance indicators and both temperature and WBGT for individual leagues. Furthermore, linear mixed models were used to determine associations across all 4 leagues, accounting for differences between them as random effects. Bonferroni corrections were applied to account for multiple tests. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Overall, combined-league data showed that total distance (95% CI, \u22120.50 to 0.37; <jats:italic>\u03b2<\/jats:italic>: \u22120.36), number of high-speed runs (95% CI, \u22124.57 to 2.93; <jats:italic>\u03b2<\/jats:italic>: \u22120.29), high-speed distances (95% CI, \u22120.07 to 0.05; <jats:italic>\u03b2<\/jats:italic>: \u22120.28), number of sprints (95% CI, \u22122.72 to 2.07; <jats:italic>\u03b2<\/jats:italic>: \u22120.39), and sprint distances (95% CI, \u22120.05 to 0.03; <jats:italic>\u03b2<\/jats:italic>: \u22120.22) were all lower when WBGT was higher (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001), whereas the peak speed recorded per match (95% CI, 0.01 to 0.03; <jats:italic>\u03b2<\/jats:italic>: 0.18) was higher when WBGT was higher (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). Models with temperature instead of WBGT derived similar results. <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> Warmer environmental conditions were associated with lower total, high-speed, and sprint distances covered. These responses may result from an increased thermoregulatory load or indirectly from an adapted individual or team-tactical pacing strategy in warmer conditions. Teams should consider strategies to counter such effects to avoid lower distances covered at high intensities that are related to success in football.<\/jats:p>","DOI":"10.1123\/ijspp.2024-0248","type":"journal-article","created":{"date-parts":[[2024,11,26]],"date-time":"2024-11-26T17:53:35Z","timestamp":1732643615000},"page":"109-119","source":"Crossref","is-referenced-by-count":14,"title":["Associations Between Match Running Performance and Environmental Temperatures in 4 Professional Football Leagues"],"prefix":"10.1123","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9901-0035","authenticated-orcid":true,"given":"Edgar","family":"Schwarz","sequence":"first","affiliation":[{"name":"Institute of Sport and Preventive Medicine, Saarland University, Saarbr\u00fccken, Germany"},{"name":"School of Sport, Exercise and Rehabilitation, Faculty of Health, University of Technology Sydney, Ultimo, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5641-1314","authenticated-orcid":true,"given":"Rob","family":"Duffield","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Rehabilitation, Faculty of Health, University of Technology Sydney, Ultimo, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2949-4150","authenticated-orcid":true,"given":"Andrew R.","family":"Novak","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Rehabilitation, Faculty of Health, University of Technology Sydney, Ultimo, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom","family":"G\u00f6rres","sequence":"additional","affiliation":[{"name":"Institute of Sport and Preventive Medicine, Saarland University, Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3425-4546","authenticated-orcid":true,"given":"Tim","family":"Meyer","sequence":"additional","affiliation":[{"name":"Institute of Sport and Preventive Medicine, Saarland University, Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"30","key":"r1","series-title":"BMJ Open Sport Exerc","doi-asserted-by":"publisher","DOI":"10.1136\/bmjsem-2023-001608","article-title":"Protective guidelines and mitigation strategies for hot conditions in professional football: starting 11 Hot Tips for consideration","volume":"9","author":"Gouttebarge V","year":"2023","unstructured":"Gouttebarge V, Duffield R, den Hollander S, Maughan R.
