Fifteen highly trained athletes randomly performed seven time trials on a 400\u00a0m track. The CP\/CS and W'\/D' were defined through the inverse of time model using the 3, 4, 5, 10, and 20 min trials. The 60 min performance was estimated through the power law model using the 1, 3, and 10 min trials and compared with the actual performance. A lower standard error of the estimate was obtained when using the power meter (CP: 2.7 [2.1\u20133.3] % and W': 13.8 [10.4\u201317.3] %) compared to the speed reported by the IMU (CS: 3.4 [2.5\u20134.3] %) and D': 20.7 [16.6\u201324.7] %) and GNSS sport watch (CS: 3.4 [2.5\u20134.3] % and D': 20.6 [16.7\u201324.7] %). A lower coefficient of variation was also observed for the power meter (4.9 [3.7\u20136.1] %) Regarding the speed reported by the IMU (10.9 [7.1\u201314.8] %) and GNSS sport watch (10.9 [7.0\u201314.7] %) in the 60 min performance estimation, the power meter offered lower errors than the IMU and GNSS sport watch for modelling endurance performance on the track.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ejsc.12210","type":"journal-article","created":{"date-parts":[[2024,10,14]],"date-time":"2024-10-14T15:13:56Z","timestamp":1728918836000},"page":"1597-1603","source":"Crossref","is-referenced-by-count":4,"title":["Power or speed: Which metric is more accurate for modelling endurance running performance on track?"],"prefix":"10.1002","volume":"24","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":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto A.","family":"\u00d1ancupil\u2010Andrade","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 Health Los Lagos University  Puerto Montt Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"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) CIBIS (Centro de Investigaci\u00f3n para el Bienestar y la Inclusi\u00f3n Social) Research Center University of Almer\u00eda  Almer\u00eda Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"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.
