Foot posture index (FPI) was used to determine pes planus. The vertical jump was measured by the VertiMetric device; horizontal jump performance by using the single leg hop test. Y Balance Test (YBT) was used to evaluate dynamic balance. The Mann-Whitney U test has been used for comparison of the groups and the alpha level is set at 0.05.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Vertical jump results of the pes planus group have been found statistically lower compared to the control group (p\u2009&lt;\u20090.05). However, there were no statistically significant differences in the horizontal jump and YBT measurements between groups (p\u2009&gt;\u20090.05). A weak negative correlation was found between the vertical jump distance and FPI scores (p\u2009&lt;\u20090.05). There was a significant weak positive relationship between the FPI scores and anterior parameter of YBT in both sides (p\u2009&lt;\u20090.05) and there were no statistically significant correlations between the posteromedial and posterolateral parameters in both sides (p\u2009&gt;\u20090.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Pes planus is associated with the only anterior reach of YBT, and vertical jumping performance; therefore, it is recommended to include strengthening and correction exercises for pes planus to improve vertical jumping performance and reduce risk of injuries.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10538127251324728","type":"journal-article","created":{"date-parts":[[2025,3,28]],"date-time":"2025-03-28T22:37:48Z","timestamp":1743201468000},"page":"1094-1105","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["How does pes planus affect jumping performance and balance ability?"],"prefix":"10.1177","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5372-0998","authenticated-orcid":false,"given":"Rigina","family":"Rakhmatova","sequence":"first","affiliation":[{"name":"Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Girne American University, Via Mersin 10, 99428, Girne, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9044-0816","authenticated-orcid":false,"given":"Mehmet","family":"Mi\u00e7oo\u011fullar\u0131","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Cyprus International University, Via Mersin 10, 99258, Lefkosa, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6847-8690","authenticated-orcid":false,"given":"Mehmet Ismet","family":"Tok","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports Teaching, School of Physical Education and Sports, Girne American University, Via Mersin 10, 99428, Girne, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,3,28]]},"reference":[{"key":"e_1_3_4_2_2","first-page":"35","article-title":"Differences in manifestation of explosive power of legs regarding to longitudinal foot arch in young athletes","volume":"34","author":"Mihajlovic I","year":"2012","unstructured":"Mihajlovic I, Petrovi\u0107 M, \u0160olaja M.
