Twelve expert male swimmers completed an incremental 7 \u00d7 200 m step test immediately after their most important winter competitions. Measurements were made of: (i) height, body mass and arm span as anthropometrical parameters; (ii) velocity at a 4 mmol\u00b7L\u22121 lactate concentration (V4), maximal oxygen uptake (VO2m\u00e1x) and energy cost (C), as physiological parameters; (iii) stroke frequency (SF), stroke length (SL), stroke index (SI) and propelling efficiency (\u03b7p) as biomechanical indicators; and (iv) 200 m front crawl race time in official long course competitions. Spearman correlation coefficients identified V4 as the single factor having significant relationship with performance. Simple regression analysis determined V4, SI and arm span as the most relevant variables of each group. Multiple linear regression models showed that physiological factors explained better (59%) the variation in performance at this stage of the season, followed by the biomechanical (14%) ones. Therefore, V4 can be one important aspect for training control and diagnosis for those who want to achieve success in the 200 m front crawl at the winter season peak.<\/jats:p>","DOI":"10.3390\/ijerph17062126","type":"journal-article","created":{"date-parts":[[2020,3,24]],"date-time":"2020-03-24T07:16:08Z","timestamp":1585034168000},"page":"2126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Modelling the 200 m Front-Crawl Performance Predictors at the Winter Season Peak"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5502-1202","authenticated-orcid":false,"given":"M\u00e1rio J.","family":"Costa","sequence":"first","affiliation":[{"name":"Department of Sport Sciences, Polytechnic Institute of Guarda, 6300-559 Guarda, Portugal"},{"name":"Research Center in Sport Sciences, Health Sciences and Human Development, CIDESD, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4592-8091","authenticated-orcid":false,"given":"Catarina C.","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2351-3047","authenticated-orcid":false,"given":"Daniel A.","family":"Marinho","sequence":"additional","affiliation":[{"name":"Research Center in Sport Sciences, Health Sciences and Human Development, CIDESD, 5001-801 Vila Real, Portugal"},{"name":"Department of Sport Sciences, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"}]},{"given":"Ant\u00f3nio J.","family":"Silva","sequence":"additional","affiliation":[{"name":"Research Center in Sport Sciences, Health Sciences and Human Development, CIDESD, 5001-801 Vila Real, Portugal"},{"name":"Department of Sport, Exercise and Health Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7071-2116","authenticated-orcid":false,"given":"Tiago M.","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Research Center in Sport Sciences, Health Sciences and Human Development, CIDESD, 5001-801 Vila Real, Portugal"},{"name":"Department of Sport Sciences, Polytechnic Institute of Bragan\u00e7a, 5300-252 Bragan\u00e7a, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"291","DOI":"10.1097\/00005768-200102000-00019","article-title":"Monitoring the lactate threshold in world ranked swimmers","volume":"33","author":"Pyne","year":"2001","journal-title":"Med.
