The question of a long\u2010term brain cumulative effect remains. Our objective was to determine whether exposure to head impacts over one soccer season was associated with changes in functional brain connectivity at rest, using magnetic resonance imaging (MRI). In this prospective cohort study, 10 semi\u2010professional men soccer players, aged 18\u201325\u00a0years, and 20 age\u2010matched men athletes without a concussion history and who do not practice any contact sport were recruited in Bordeaux (France). Exposure to head impacts per soccer player during competitive games over one season was measured using video analysis. Resting\u2010state functional magnetic resonance imaging data were acquired for both groups at two times, before and after the season. With a seed\u2010based analysis, resting\u2010state networks that have been intimately associated with aspects of cognitive functioning were investigated. The results showed a mean head impacts of 42 (\u00b133) per soccer player over the season, mainly intentional head\u2010to\u2010ball impacts and no concussion. No head impact was found among the other athletes. The number of head impacts between the two MRI acquisitions before and after the season was associated with increased connectivity within the default mode network and the cortico\u2010cerebellar network. In conclusion, our findings suggest that the brain functioning changes over one soccer season in association with exposure to repetitive head impacts.<\/jats:p>","DOI":"10.1002\/jnr.24742","type":"journal-article","created":{"date-parts":[[2020,10,22]],"date-time":"2020-10-22T06:48:54Z","timestamp":1603349334000},"page":"446-454","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Changes in resting\u2010state functional brain connectivity associated with head impacts over one men\u2019s semi\u2010professional soccer season"],"prefix":"10.1002","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9384-5410","authenticated-orcid":false,"given":"H\u00e9l\u00e8ne","family":"Cassoudesalle","sequence":"first","affiliation":[{"name":"Physical and Rehabilitation Medicine Department University Hospital of Bordeaux Bordeaux France"},{"name":"\u201cHandicap, Activity, Cognition &amp;
