Methods: Fourteen male XC skiers were monitored during a 10 km (3 \u00d7 3.3 km) skating time-trial competition. On separate days, the skiers performed body composition assessments, laboratory tests while roller-ski skating and a 3 km uphill skating field test. Results: Time in uphill terrain was most strongly correlated with overall performance (r = 0.99, p &lt; 0.01). G2 and G3 were the predominant sub-techniques (61% of overall time) with more use of G2 on lap three compared to lap one (p &lt; 0.05). Body mass and lean mass were inversely correlated with overall and uphill performance (r = \u22120.60\u20130.75, all p &lt; 0.05). VO2 at 4 mmol\u00b7L\u22121, VO2peak and TTE while roller-ski skating in the laboratory and the 3 km uphill skating field test correlated with overall performance (r = \u22120.66\u20130.85, all p &lt; 0.05). Conclusions: Time in uphill terrain was the main contributor to overall performance, and G3 and G2 the most used sub-techniques with increased utilization of G2 throughout the competition. VO2peak and TTE while roller-ski skating in the laboratory and performance in an uphill skating field test had the strongest associations with time-trial performance.<\/jats:p>","DOI":"10.3390\/ijerph191811580","type":"journal-article","created":{"date-parts":[[2022,9,14]],"date-time":"2022-09-14T20:50:45Z","timestamp":1663188645000},"page":"11580","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Analysis of a Skating Time-Trial Competition and Associated Performance-Determinants in Cross-Country Skiers"],"prefix":"10.3390","volume":"19","author":[{"given":"Lei","family":"Shang","sequence":"first","affiliation":[{"name":"Institute of Competitive Sports, Beijing Sport University, Beijing 100084, China"},{"name":"Centre for Sports Research, China Institute of Sport Science, Beijing 100061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00d8yvind","family":"Sandbakk","sequence":"additional","affiliation":[{"name":"Centre for Elite Sports Research, Department of Neuromedicine and Movement Science, Norwegian University of Science and Technology, 7030 Trondheim, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruiying","family":"Shi","sequence":"additional","affiliation":[{"name":"National Academy of Economic Strategy, Chinese Academy of Social Sciences, Beijing 100006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoping","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Competitive Sports, Beijing Sport University, Beijing 100084, China"},{"name":"Centre for Sports Research, China Institute of Sport Science, Beijing 100061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rune Kj\u00f8sen","family":"Talsnes","sequence":"additional","affiliation":[{"name":"Mer\u00e5ker High School, Tr\u00f8ndelag County Council, 7735 Steinkjer, Norway"},{"name":"Department of Sports Science and Physical Education, Nord University, 8026 Bod\u00f8, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1675","DOI":"10.1007\/s00421-019-04158-x","article-title":"Energy system contribution during competitive cross-country skiing","volume":"119","author":"Losnegard","year":"2019","journal-title":"Eur.
