This study examined the effect of\n                    pubertal status on PAPE after a maximal cardiopulmonary exercise test (CPET) in\n                    48 male soccer players aged 10\u201318 years. Additionally, we investigated the\n                    relationship between maximal aerobic speed (MAS) and lower limb strength. They\n                    were classified as pre-pubescent (n=13), pubescent (n=15), and post-pubescent\n                    (n=20). The participants performed three countermovement jumps (CMJ) before and\n                    after a maximal CPET. The PAPE was estimated by calculating the difference\n                    between pre- and post-exercise CMJ height at five minutes of recovery after\n                    CPET. The CPET was performed on a treadmill using a ramp protocol to determine\n                    the maximal oxygen consumption (VO2 max) and MAS. CMJ height was\n                    significantly greater after the CPET for all groups. Post-pubescent participants\n                    had significantly greater PAPE than both pre-pubescents and pubescents.\n                    Pre-pubescents had significantly lower CMJ height, VO2 max, and MAS\n                    compared to pubescent and post-pubescents. Finally, a positive relationship was\n                    observed between MAS and CMJ height. In conclusion, PAPE after maximal CPET was\n                    observed in all pubertal cohorts of young soccer players. However, it was\n                    greater in post-pubescent children. Finally, MAS was positively correlated with\n                    lower limbs strength.<\/jats:p>","DOI":"10.1055\/a-2358-3840","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T00:28:18Z","timestamp":1745368098000},"source":"Crossref","is-referenced-by-count":1,"special_numbering":"S","title":["The Effect of Pubertal Status on Post-activation Performance\n                    Enhancement in Young Soccer Players"],"prefix":"10.1055","volume":"09","author":[{"given":"Renato Ferreira","family":"Estrella","sequence":"additional","affiliation":[{"name":"Deparment of Physical Education, Joaquim Grava Institute, S\u00e3o Paulo,\n                    Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1992-5199","authenticated-orcid":false,"given":"Valmir","family":"Oliveira Silvino","sequence":"additional","affiliation":[{"name":"Department of Biophysics and Physiology, Nucleus of Study in Physiology\n                    Applied to Performance and Health (NEFADS), Federal University of Piaui,\n                    Teresina, Brazil"},{"name":"Rede Nordeste de Biotecnologia (RENORBIO), Universidade Federal do\n                    Piau\u00ed, Teresina, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatiane","family":"Ferraz","sequence":"additional","affiliation":[{"name":"Deparment of Physical Education, Joaquim Grava Institute, S\u00e3o Paulo,\n                    Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquim Paulo Grava","family":"de Souza","sequence":"additional","affiliation":[{"name":"Deparment of Physical Education, Joaquim Grava Institute, S\u00e3o Paulo,\n                    Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos Antonio Pereira dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Biophysics and Physiology, Nucleus of Study in Physiology\n                    Applied to Performance and Health (NEFADS), Federal University of Piaui,\n                    Teresina, Brazil"},{"name":"Rede Nordeste de Biotecnologia (RENORBIO), Universidade Federal do\n                    Piau\u00ed, Teresina, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danilo Marcelo Leite","family":"Prado","sequence":"additional","affiliation":[{"name":"Human Performance Laboratory, Ultra Spors Science, S\u00e3o Paulo,\n                    Brazil"},{"name":"Heart Institute, USP, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,4,22]]},"reference":[{"key":"ref1","first-page":"399","article-title":"The dream of being a professional soccer player","volume":"27","author":"A Bourke","year":"2003","journal-title":"J Sport Soc Issues"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"1269","DOI":"10.1080\/02640414.2020.1752440","article-title":"A survey of talent identification and development processes in the youth\n                    academies of professional soccer clubs from around the world","volume":"38","author":"P R Ford","year":"2020","journal-title":"J Sports Sci"},{"key":"ref3","first-page":"32","article-title":"Science or coaches\u2019 eye? \u2013 Both!
