Between races, intervention received video- and sensor-based feedback through a theoretical lecture and a practical training session aiming to implement a terrain-specific micropacing strategy focusing on active power production over designated hilltops to save time in the subsequent downhill. The control group only received their overall results and performed a training session with matched training load. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> From Race1 to Race2, the intervention group increased the total variation of chest acceleration on all hilltops (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001) and reduced time compared with the control group in a specifically targeted downhill segment (mean group difference: \u22120.55\u00a0s; 95% confidence interval [CI], \u22120.9 to \u22120.19\u00a0s; <jats:italic>P<\/jats:italic>\u2009=\u2009.003), as well as in overall time spent in downhill (\u221214.4\u00a0s; 95% CI, \u221221.4 to \u22127.4\u00a0s; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001) and flat terrain (\u22126.5\u00a0s; 95% CI, \u221211.0 to \u22121.9\u00a0s; <jats:italic>P<\/jats:italic>\u2009=\u2009.006). No between-groups differences were found for either overall uphill terrain (\u22129.3\u00a0s; 95% CI, \u221231.2 to 13.2\u00a0s; <jats:italic>P<\/jats:italic>\u2009=\u2009.426) or total race time (\u221232.2\u00a0s; 95% CI, \u2212100.2 to 35.9\u00a0s; <jats:italic>P<\/jats:italic>\u2009=\u2009.339). <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> Targeted training combined with video- and sensor-based feedback led to a successful implementation of a terrain-specific micropacing strategy in XC skiing, which reduced the time spent in downhill and flat terrain for intervention compared with a control group. However, no change in overall performance was observed between the 2 groups of XC skiers.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0106","type":"journal-article","created":{"date-parts":[[2022,10,21]],"date-time":"2022-10-21T15:27:05Z","timestamp":1666366025000},"page":"1672-1682","source":"Crossref","is-referenced-by-count":12,"title":["Performance Effects of Video- and Sensor-Based Feedback for Implementing a Terrain-Specific Micropacing Strategy in Cross-Country Skiing"],"prefix":"10.1123","volume":"17","author":[{"given":"Trine M.","family":"Seeberg","sequence":"first","affiliation":[{"name":"Department of Neuromedicine and Movement Science, Center for Elite Sports Research, Norwegian University of Science and Technology, Trondheim, Norway"},{"name":"Smart Sensors and Microsystems, SINTEF Digital, SINTEF AS, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Kocbach","sequence":"additional","affiliation":[{"name":"Department of Neuromedicine and Movement Science, Center for Elite Sports Research, Norwegian University of Science and Technology, Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rune","family":"Kj\u00f8sen Talsnes","sequence":"additional","affiliation":[{"name":"Mer\u00e5ker High School, Tr\u00f8ndelag County Council, Steinkjer, Norway"},{"name":"Department of Sports Science and Physical Education, Nord University, Bod\u00f8, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederic","family":"Meyer","sequence":"additional","affiliation":[{"name":"Group for Digital Signal Processing and Image Analysis, Department of Informatics, University of Oslo, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Losnegard","sequence":"additional","affiliation":[{"name":"Department of Physical Performance, Norwegian School of Sport Sciences, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Tj\u00f8nn\u00e5s","sequence":"additional","affiliation":[{"name":"Smart Sensors and Microsystems, SINTEF Digital, SINTEF AS, Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d8yvind","family":"Sandbakk","sequence":"additional","affiliation":[{"name":"Department of Neuromedicine and Movement Science, Center for Elite Sports Research, Norwegian University of Science and Technology, Trondheim, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guro Str\u00f8m","family":"Solli","sequence":"additional","affiliation":[{"name":"Department of Sports Science and Physical Education, Nord University, Bod\u00f8, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"8","key":"r1","series-title":"Eur J Appl Physiol","doi-asserted-by":"publisher","first-page":"1675","DOI":"10.1007\/s00421-019-04158-x","article-title":"Energy system contribution during competitive cross-country skiing","volume":"119","author":"Losnegard T","year":"2019","unstructured":"Losnegard T.
