Both groups completed their respective training regimens twice a week for 6\u00a0weeks. Measurements for VO2max, O2 cost, time to exhaustion (TTE), and running times for 100, 400, and 3000\u00a0m were taken before and after the intervention.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results indicated that the IT group showed significant improvements in TTE and running performance across 100, 400, and 3000\u00a0m (all P &amp;lt; 0.01), while the CT group only demonstrated improvements in 400\u00a0m time (P &amp;lt; 0.01). The IT group exhibited superior 3000\u00a0m performance compared to the CT group (P &amp;lt; 0.01). Analysis of effect sizes revealed small to moderate improvements in physiological and performance measures for the IT group, with VO2max showing a small effect size of 0.43, O2 cost a moderate effect size of 0.65, and TTE a moderate effect size of 0.77.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These findings suggest that sprint interval training may offer superior benefits for enhancing running performance of well-trained male distance runners, particularly in time to exhaustion and middle-to long-distance events, compared to traditional longdistance training.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphys.2025.1536287","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T07:11:58Z","timestamp":1738825918000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of 6-week sprint interval training compared to traditional training on the running performance of distance runners: a randomized controlled trail"],"prefix":"10.3389","volume":"16","author":[{"given":"Kai","family":"Jin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengbiao","family":"Cai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongqian","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,2,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"574","DOI":"10.1249\/MSS.0b013e31815e728f","article-title":"Similar sensitivity of time to exhaustion and time-trial time to changes in endurance","volume":"40","author":"Amann","year":"2008","journal-title":"Med.
