Thus, the aim was to identify and describe young athletes\u2019 PA and SED off-training, according to daily life activities. Eight athletes (15.7 \u00b1 2 years, 1.72 \u00b1 0.6 m height, 62.9 \u00b1 10.2 kg) of a sport talent program wore on their waist a tri-axial accelerometer (ActiGraph\u00ae wGT9X-link, Shalimar, FL, USA) at 30 Hz for 15 consecutive days, and reported their schedule. A two-step cluster analysis classified three groups according to sedentary PA and MVPA. The Sedentary (56.9%), presented the highest sedentary PA (mean [CI], 37.37 [36.45\u201338.29] min\/hour); The Hazardous (19.4%) had the lowest values of sedentary and MVPA (10.07 [9.41\u201310.36] min\/hour and 8.67 [7.64\u20139.70] min\/hour, respectively). Balanced (23.7%) had the highest MVPA (28.61 [27.16\u201330.07] min\/hour). Sedentary had the lowest count of home time associated (20%) and higher school (26%) time when compared to the Hazardous (13%). The Balanced showed the highest count of school (61%) and home time (47%). Different profiles for young athletes revealed alarming behavior in the associations with sedentary PA, sitting and SED breaks, which may influence performance and health.<\/jats:p>","DOI":"10.3390\/sports6040141","type":"journal-article","created":{"date-parts":[[2018,11,7]],"date-time":"2018-11-07T03:45:22Z","timestamp":1541562322000},"page":"141","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Off-Training Levels of Physical Activity and Sedentary Behavior in Young Athletes: Preliminary Results during a Typical Week"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4409-7329","authenticated-orcid":false,"given":"Juliana","family":"Exel","sequence":"first","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7275-9161","authenticated-orcid":false,"given":"Nuno","family":"Mateus","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2165-2687","authenticated-orcid":false,"given":"Bruno","family":"Travassos","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and Human Development, CIDESD, Sport Sciences Department, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7874-4104","authenticated-orcid":false,"given":"Bruno","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]},{"given":"Isabel","family":"Gomes","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5181-6390","authenticated-orcid":false,"given":"Nuno","family":"Leite","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2335-9991","authenticated-orcid":false,"given":"Jaime","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community, University of Tr\u00e1s-os-Montes e Alto Douro, UTAD, Quinta de Prados, 5001-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1186\/s12966-017-0481-3","article-title":"Sedentary patterns, physical activity and health-related physical fitness in youth: A cross-sectional study","volume":"14","author":"Judice","year":"2017","journal-title":"Int.
