The MC was divided into menstrual bleeding (MB), days 1 to 5; premenstruation (PM), 1 to 4 days before the start of the next MC; and mid-phase (MP), the remaining days. Ski jumping results were recalculated to adjust for wind points and take-off speed to get a physical performance score (\n S<\/jats:italic>\n pp<\/jats:sub>\n ). Data are reported as median (interquartile range).\n \n Results<\/jats:italic>\n <\/jats:bold>\n :<\/jats:italic>\n MC length was 24 days (20\u201326), and symptom severity of depressive and physical symptoms was highest during the last 2 days of the cycle. Resting heart rate was 45 (43\u201347) beats\/min in MB, 47 (45\u201348) beats\/min in MP, and 48 (45\u201349) beats\/min in PM. Heart rate variability was 78 (67\u201382) ms in MB, 70 (65\u201376) ms in MP, and 74 (67\u201385) ms in PM. Performance data in normal hill and large hill followed somewhat opposite patterns, with a potentially better performance in normal hill and worse in large hill during PM.\n \n Conclusion<\/jats:italic>\n <\/jats:bold>\n :<\/jats:italic>\n Recovery measures and performance in individual athletes can be influenced by MC phase, with these seemingly being most influenced by cycle-related symptoms.\n <\/jats:p>","DOI":"10.1123\/ijspp.2026-0022","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T18:04:47Z","timestamp":1785780287000},"page":"1-5","source":"Crossref","is-referenced-by-count":0,"title":["The Influence of Menstrual Cycle Phase on Recovery Measures and Performance: A Case Study From Ski Jumping"],"prefix":"10.1123","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3161-9767","authenticated-orcid":true,"given":"Emilie E.","family":"Asp","sequence":"first","affiliation":[{"name":"Centre for Elite Sports Research, Department of Neuromedicine and Movement Science, Norwegian University of Science and Technology, Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1229-8508","authenticated-orcid":true,"given":"Ola A.","family":"Elfmark","sequence":"additional","affiliation":[{"name":"Centre for Elite Sports Research, Department of Neuromedicine and Movement Science, Norwegian University of Science and Technology, Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1630-4696","authenticated-orcid":true,"given":"Dionne A.","family":"Noordhof","sequence":"additional","affiliation":[{"name":"Centre for Elite Sports Research, Department of Neuromedicine and Movement Science, Norwegian University of Science and Technology, Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"6","key":"r1","series-title":"Women Sport Phys Act J","doi-asserted-by":"publisher","first-page":"18","DOI":"10.1123\/wspaj.2022-0026","article-title":"Mechanisms underlying menstrual cycle effects on exercise performance: a scoping review","volume":"31","author":"Bernstein C","year":"2023","unstructured":"Bernstein C, Behringer M.
