Exercise intensity and competition load (TL) were assessed using running power, heart rate, and rating of perceived exertion (RPE). <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> The highest exercise intensity was observed in Vertical race (3.9 [0.4]\u00a0W\u00b7kg<jats:sup>\u22121<\/jats:sup>, 93.6% [2.8%] HR<jats:sub>max<\/jats:sub>, and 9.5 [0.7] RPE) compared to Sky race (3.5 [0.5]\u00a0W\u00b7kg<jats:sup>\u22121<\/jats:sup>, 89.9% [2.4%] HR<jats:sub>max<\/jats:sub>, and 8.5 [1.2] RPE), and SkyUltra (2.7 [0.6]\u00a0W\u00b7kg<jats:sup>\u22121<\/jats:sup>, 73.4% [1.1%] HR<jats:sub>max<\/jats:sub>, and 8.2 [1.1] RPE). Vertical races had the highest mean maximal power outputs for periods &lt;10\u00a0minutes. They also had the highest proportion of time spent &gt;5\u00a0W\u00b7kg<jats:sup>\u22121<\/jats:sup> and the most time spent above the respiratory compensation threshold. The majority of time in SkyUltra was spent at low intensity. The highest TLs were observed in these races (6200.5 [708.0]\u00a0kJ, 842.0 [35.7]\u00a0AU for TL<jats:sub>HR<\/jats:sub>, and 4897.3 [940.7]\u00a0AU for TL<jats:sub>RPE<\/jats:sub>). However, when normalized to competition time, the SkyUltra event showed the lowest values compared with the Vertical and Sky races (\u223c11 vs \u223c14.5\u00a0kJ\u00b7min<jats:sup>\u22121<\/jats:sup>, \u223c1.5 vs \u223c2.5\u00a0AU\u00b7m<jats:sup>\u22121<\/jats:sup> for TL<jats:sub>HR<\/jats:sub>). <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> The results of this study expand knowledge about the effort demands of mountain races and demonstrate how these demands are affected by race duration. Additionally, the study highlights the potential use of running power for quantifying exercise in this sport.<\/jats:p>","DOI":"10.1123\/ijspp.2024-0234","type":"journal-article","created":{"date-parts":[[2024,12,28]],"date-time":"2024-12-28T15:22:36Z","timestamp":1735399356000},"page":"275-281","source":"Crossref","is-referenced-by-count":4,"title":["Analyzing Competitive Demands in Mountain Running Races: A Running Power-Based Approach"],"prefix":"10.1123","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1682-0292","authenticated-orcid":true,"given":"Juan","family":"Rodr\u00edguez-Medina","sequence":"first","affiliation":[{"name":"Department of Physical Education and Sports, Institute of Biomedicine (IBIOMED), Universidad de Le\u00f3n, Le\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2881-5645","authenticated-orcid":true,"given":"Bel\u00e9n","family":"Carballo-Leyenda","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Institute of Biomedicine (IBIOMED), Universidad de Le\u00f3n, Le\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3723-6132","authenticated-orcid":true,"given":"Jorge","family":"Guti\u00e9rrez-Arroyo","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Institute of Biomedicine (IBIOMED), Universidad de Le\u00f3n, Le\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6697-2887","authenticated-orcid":true,"given":"Fabio","family":"Garc\u00eda-Heras","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Institute of Biomedicine (IBIOMED), Universidad de Le\u00f3n, Le\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9157-1532","authenticated-orcid":true,"given":"Jose A.","family":"Rodr\u00edguez-Marroyo","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Institute of Biomedicine (IBIOMED), Universidad de Le\u00f3n, Le\u00f3n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"3","key":"r1","series-title":"Appl Physiol Nutr Metab","doi-asserted-by":"publisher","first-page":"269","DOI":"10.1139\/apnm-2014-0263","article-title":"Psychophysiological response and energy balance during a 14-h ultraendurance mountain running event","volume":"40","author":"Clemente-Su\u00e1rez VJ","year":"2015","unstructured":"Clemente-Su\u00e1rez VJ.
