The aim of this present study was to investigate the similarities and differences in roller skiing and on-snow skiing with the diagonal stride (DS) technique. Six youth (age: 14.3 \u00b1 2.9 years) skiers participated in this study. Two high-definition video camcorders and FastMove 3D Motion 2.23.3.3101 were used to obtain the three-dimensional kinematic data. The cycle characteristics and joint angle ROM of the DS technique while skiing on different surfaces were similar. Almost all joint angle\u2013time curves that were obtained from roller skiing showed a moderate-to-high degree of similarity to the angle\u2013time curves obtained from on-snow skiing, except the hip adduction\u2013abduction angle. The differences between roller skiing and on-snow skiing were mainly found in the body and calf anteversion angles, and the joint angles at critical instants. DS roller skiing can simulate DS on-snow skiing to a large extent in youth athletes. The hip movement, knee flexion, and calf anteversion at ski\/roller ski touchdown and take-off, pole inclination at pole touchdown, body anteversion angle, and trunk anteversion angle at pole touchdown were the points that required caution when transferring preseason practice roller skiing to on-snow skiing.<\/jats:p>","DOI":"10.3390\/s24051412","type":"journal-article","created":{"date-parts":[[2024,2,22]],"date-time":"2024-02-22T08:34:35Z","timestamp":1708590875000},"page":"1412","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comparative Analysis of the Diagonal Stride Technique during Roller Skiing and On-Snow Skiing in Youth Cross-Country Skiers"],"prefix":"10.3390","volume":"24","author":[{"given":"Mujia","family":"Ma","sequence":"first","affiliation":[{"name":"School of Sport Science, Beijing Sport University, Beijing 100084, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7690-9582","authenticated-orcid":false,"given":"Shuang","family":"Zhao","sequence":"additional","affiliation":[{"name":"China Institute of Sport and Health Science, Beijing Sport University, Beijing 100084, China"},{"name":"Dalian Fast Move Technology Co., Ltd., Dalian 116033, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5580-1487","authenticated-orcid":false,"given":"Ting","family":"Long","sequence":"additional","affiliation":[{"name":"Auckland Bioengineering Institute, University of Auckland, Auckland 1010, New Zealand"}]},{"given":"Qingquan","family":"Song","sequence":"additional","affiliation":[{"name":"School of Strength and Conditioning Training, Beijing Sport University, Beijing 100084, China"}]},{"given":"Hans-Christer","family":"Holmberg","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Mid Sweden University, 831 25 \u00d6stersund, Sweden"}]},{"given":"Hui","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Sport Science, Beijing Sport University, Beijing 100084, China"},{"name":"China Institute of Sport and Health Science, Beijing Sport University, Beijing 100084, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.3389\/fphys.2017.00094","article-title":"The role of power fluctuations in the preference of diagonal vs. double poling sub-technique at different incline-speed combinations in elite cross-country skiers","volume":"8","author":"Dahl","year":"2017","journal-title":"Front.
