Nineteen recreational runners (10 males and 9 females and maximum oxygen uptake: 53.0\u00a0\u00b1\u00a04.7\u00a0mL\/kg\/min) performed a graded exercise test (GXT) to determine the VT2 and MAP. On a second test, athletes performed two\u2010time trials of 9 and 3 min interspaced by 30 min. The CP was determined from the linear CP model and compared with the power output associated with the VT2. The MAP was determined from the linear Peronnet model, established at 7 min, and compared with the MAP determined in the GXT. The CP model was valid for determining the VT2, regardless of sex (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.130; 9\/3 vs. GXT: 3.5 [\u22121.1 to 8.2] W). The MAP was overestimated (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.015) specifically in males (9\/3 vs. GXT: 9.2 [3.3 to 15.1] W) rather than in females (<jats:italic>p<\/jats:italic>\u00a0=\u00a09\/3 vs. GXT: 1.7 [\u22124.4 to 8.0] W). Therefore, MAP estimates were determined introducing the CP and W' parameters to a stepwise multiple linear regression analysis. For females, the CP was the unique significant predictor of MAP (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) explaining 96.7% of the variance. In males, both CP and W' were significant predictors of MAP (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) explaining 97.7% of the variance. Practitioners can validly estimate the VT2 and MAP through a practical testing protocol in both male and female recreational runners.<\/jats:p>","DOI":"10.1002\/ejsc.12254","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T03:39:34Z","timestamp":1737949174000},"source":"Crossref","is-referenced-by-count":1,"title":["The 9\/3 Min Running Test: A Simple and Practical Approach to Estimate the Critical and Maximal Aerobic Power"],"prefix":"10.1002","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8295-979X","authenticated-orcid":false,"given":"Santiago A.","family":"Ruiz\u2010Alias","sequence":"first","affiliation":[{"name":"Department of Physical Education and Sports Faculty of Sport Sciences University of Granada  Granada Spain"},{"name":"Sport and Health University Research Center (iMUDS) University of Granada  Granada Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aitor","family":"Marcos\u2010Blanco","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports Faculty of Sport Sciences University of Granada  Granada Spain"},{"name":"Sport and Health University Research Center (iMUDS) University of Granada  Granada Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iv\u00e1n","family":"Fern\u00e1ndez\u2010Navarrete","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports Faculty of Sport Sciences University of Granada  Granada Spain"},{"name":"Sport and Health University Research Center (iMUDS) University of Granada  Granada Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5535-2087","authenticated-orcid":false,"given":"Alejandro","family":"P\u00e9rez\u2010Castilla","sequence":"additional","affiliation":[{"name":"Department of Education Faculty of Education Sciences University of Almer\u00eda  Almer\u00eda Spain"},{"name":"SPORT Research Group (CTS\u20101024) CERNEP Research Center University of Almer\u00eda  Almer\u00eda Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7518-8234","authenticated-orcid":false,"given":"Felipe","family":"Garc\u00eda\u2010Pinillos","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports Faculty of Sport Sciences University of Granada  Granada Spain"},{"name":"Sport and Health University Research Center (iMUDS) University of Granada  Granada Spain"},{"name":"Department of Physical Education Sports and Recreation.
