The pooled dataset included 24\u2009804 males and 5413 females aged 6\u201375\u2009years. CMJ height (cm) was measured on a contact mat from flight time(s), and peak power (W) was estimated using equations for adults and children and expressed also relative to body mass (W\/kg). Five\u2010year age groups were formed for mean comparison. CMJ height and peak power increased throughout childhood and adolescence. From ages 11 to 15, males exhibited greater CMJ height and peak power than females. Based on mean values, CMJ height peaked at ages 16\u201320 and peak power at 21\u201325 in males, while both peaked at 21\u201325 in females. Males maintained their level until 26\u201330\u2009years, whereas females showed a decline after the peak. Segmented regression models indicated earlier peaks for CMJ height (18\u2009years in males, 17 in females) and slightly later peaks for peak power (21\u2009years in males, 19 in females). Before the peaking age, annual relative increases calculated over 11\u201315\u2009years were 5.6% versus 3.1% for CMJ height and 4.7%\u20137.6% vs. 4.0%\u20137.3% for peak power (males vs. females). After the peaking age, annual declines calculated over 52\u201358\u2009years were 0.9% for CMJ height and 0.3%\u20130.7% for peak power in both sexes. The results provide insights into life\u2010course patterns and the transitional period of late adolescence and early adulthood, when jumping performance peaks and evidence is limited.<\/jats:p>","DOI":"10.1111\/sms.70322","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T04:55:58Z","timestamp":1781844958000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Age and Sex on Lower Extremity Power Production Capacity Throughout the Lifespan Based on 30\u2009217 Finnish Participant Data"],"prefix":"10.1111","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0710-0069","authenticated-orcid":false,"given":"Kaisa","family":"Koivunen","sequence":"first","affiliation":[{"name":"Faculty of Sport and Health Sciences and Gerontology Research Center University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6655-9489","authenticated-orcid":false,"given":"Eija K.","family":"Laakkonen","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences and Gerontology Research Center University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2305-4741","authenticated-orcid":false,"given":"Juha P.","family":"Ahtiainen","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences, NeuroMuscular Research Center University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6804-0741","authenticated-orcid":false,"given":"Simon","family":"Walker","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences, NeuroMuscular Research Center University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph19031661"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0000000000000648"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/ijo.2016.22"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00475.2016"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00637.2010"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/55.4.M192"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/58.8.M728"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532\u20105415.2004.52022.x"},{"issue":"4","key":"e_1_2_12_10_1","first-page":"256","article-title":"Reproducibility of Jumping Mechanography in Healthy Children and Adults","volume":"10","author":"Veilleux L.
