This study also aimed to determine whether cyclists born at high altitudes tend to be more successful. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> Eighty riders aged between 17 and 22\u00a0years of 3 performance levels (U23 world-class level, WC, n\u2009=\u20098; U23 national level, N23, n\u2009=\u200941; junior national level, J, n\u2009=\u200931) and 3 altitude levels (&lt;800\u00a0m, low; 800\u20132000\u00a0m, moderate; &gt;2000\u00a0m, high) performed an ergocycle maximal incremental test to exhaustion at an altitude of 2570\u00a0m. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Altogether, while cyclists born at an altitude &gt;2000\u00a0m represented \u223c50% of the analyzed sample, there was a significantly higher proportion (84%) of these cyclists who had participated as professionals in a Grand Tour (<jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup>[1, N\u2009=\u200980]\u2009=\u20094.58, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.05). Riders of the low group had lower values of PPO and estVO<jats:sub>2<\/jats:sub>max than cyclists of moderate and high altitudes, while no differences were noted between moderate- and high-altitude groups. In N23, PPO and estVO<jats:sub>2<\/jats:sub>max were lower in the low- than in the moderate-altitude group, while in the J cyclists, PPO and estVO<jats:sub>2<\/jats:sub>max were lower in the low-altitude compared with both moderate- and high-altitude groups. <jats:italic><jats:bold>Discussion<\/jats:bold>:<\/jats:italic> Among the cyclists tested at altitude in junior and U23, there is an overrepresentation of individuals who reached an elite level and were born at a high altitude (&gt;2000\u00a0m). As no clear differences were observed between moderate- and high-altitude cyclists, the higher prevalence of elite cyclists in the latter group may originate from various\u2014still unclear\u2014mechanisms.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0245","type":"journal-article","created":{"date-parts":[[2022,11,12]],"date-time":"2022-11-12T06:20:40Z","timestamp":1668234040000},"page":"1756-1759","source":"Crossref","is-referenced-by-count":0,"title":["Does Altitude of Birth Influence the Performance of National- to Elite-Level Colombian Cyclists?"],"prefix":"10.1123","volume":"17","author":[{"given":"Mauricio","family":"Garzon","sequence":"first","affiliation":[{"name":"School of Kinesiology and Physical Activity Sciences (EKSAP), Faculty of Medicine, Universit\u00e9 de Montr\u00e9al, Montr\u00e9al, QC, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenaro","family":"Leguizamo","sequence":"additional","affiliation":[{"name":"Jenaro Sport Group & SaldaTraining, Sogamoso, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Saldarriaga","sequence":"additional","affiliation":[{"name":"Jenaro Sport Group & SaldaTraining, Sogamoso, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edgar","family":"Galeano","sequence":"additional","affiliation":[{"name":"Sports Science Center, Colombian Ministry of Sports, Bogota, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gr\u00e9goire P.","family":"Millet","sequence":"additional","affiliation":[{"name":"Institute of Sport Sciences, University of Lausanne, Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"2","key":"r1","series-title":"Eur J Appl Physiol","doi-asserted-by":"publisher","first-page":"301","DOI":"10.1007\/s00421-021-04833-y","article-title":"Power profiling and the power-duration relationship in cycling: a narrative review","volume":"122","author":"Leo P","year":"2022","unstructured":"Leo P, Spragg J, Podlogar T, Lawley JS, Mujika I.
