However, scientific evidence concerning the actual risk of these RHI on brain health remains inconclusive. Moreover, female athletes\u2014despite a presumably increased vulnerability toward the effects of RHI\u2014are largely underrepresented in previous approaches. Therefore, our aim was to prospectively investigate the effects of heading on cognitive and sensorimotor performances, health perception, and concussion symptoms in semi-professional female soccer players.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>An extensive test battery was used to assess cognitive and sensorimotor performances as well as health status (SF-36) and concussion symptoms (SCAT3) of a total of 27 female soccer players (22.2 \u00b1 4.2 years) and 15 control subjects (23.2 \u00b1 3.0 years) before and after one-and-a-half years. Throughout this period, soccer players\u2019 heading exposure was determined using video analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Subgroup comparisons (control [<jats:italic>n<\/jats:italic> = 12], low exposure [<jats:italic>n<\/jats:italic> = 7], high exposure [<jats:italic>n<\/jats:italic> = 8]) showed no time-dependent differences in SF-36 or SCAT3 scores. Similarly, across most behavioral tests, soccer players\u2019 performances evolved equally or more favorably as compared to the control subjects. However, there were significant effects pointing toward slightly negative consequences of heading on aspects of fine motor control (<jats:italic>p<\/jats:italic> = 0.001), which were confirmed by correlation and multiple regression analyses. The latter, further, yielded indications for a relationship between heading exposure and negative alterations in postural control (<jats:italic>p<\/jats:italic> = 0.002).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Our findings do not provide evidence for negative effects of soccer heading on female players\u2019 health perception, concussion symptoms, and cognitive performances over the course of one-and-a-half years. However, we found subtle negative alterations in fine motor and postural control that could be attributed to heading exposure. Other factors, like the number of previous head injuries, were not linked to the observed changes. Given the reduction of our initial sample size due to player fluctuation, the results need to be interpreted with caution and validated in larger-scale studies. These should not only focus on cognitive outcomes but also consider sensorimotor changes as a result of RHI from soccer heading.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnhum.2024.1345868","type":"journal-article","created":{"date-parts":[[2024,2,9]],"date-time":"2024-02-09T04:35:06Z","timestamp":1707453306000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["A prospective investigation of the effects of soccer heading on cognitive and sensorimotor performances in semi-professional female players"],"prefix":"10.3389","volume":"18","author":[{"given":"Jan","family":"Kern","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Gulde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim","family":"Hermsd\u00f6rfer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e1776","DOI":"10.1212\/WNL.0000000000010244","article-title":"Soccer heading and subclinical neuropsychiatric symptomatology in professional soccer players.","volume":"95","author":"Amitay","year":"2020","journal-title":"Neurology"},{"key":"B2","doi-asserted-by":"publisher","first-page":"181","DOI":"10.1080\/24733938.2020.1846769","article-title":"Immediate effects of an acute bout of repeated soccer heading on cognitive performance.","volume":"5","author":"Ashton","year":"2021","journal-title":"Sci.
