The sample for the present study comprised 157 children (boys n= 64 and girls n= 93), aged 8 to 16 years old. Based on activities\u2019 intensity (MET), the daily time spent in moderate-to-vigorous physical activity (MVPA) was calculated using an equation regression developed for adults. In addition, based on the same procedures (MET)data were analysed using the cut-off points (ranging between 614 counts. min- 1 at 6 years old to 1880 counts. min-1 for 16 years old) specially developed for children. The data analysis from youth\u2019s cut-off points reveal that both sexes engaged in significantly ( p= 0.01) more MVPA when compared with cut-off points designed for adults. Boys engaged in significantly ( p= 0.01) more MVPA activities than girls regardless of the CSA cut-off point used. Our data also showed that, except for boys aged 14\u201316 years old, the percentage of students that reach the physical activity health-related criteria (at least 60 minutes of MVPA\/day) was significantly higher in both boys (77.3% vs 93.9%; p&lt; 0.05) andgirls (50% vs 79.3%; p&lt; 0.01) when the youth\u2019s cut-off point was used. The youth-specific cut-off points used could be an important improvement in studies that develop prescription guidelines for children and adolescents. This still needs to be refined, and as a result healthrelated criteria for young people need to be based on further research evidence.<\/jats:p>","DOI":"10.1177\/1356336x03009001181","type":"journal-article","created":{"date-parts":[[2003,4,28]],"date-time":"2003-04-28T06:30:40Z","timestamp":1051511440000},"page":"75-85","source":"Crossref","is-referenced-by-count":11,"title":["Assessment of Children\u00eds and Adolescents\u00ed Physical Activity Levels"],"prefix":"10.1177","volume":"9","author":[{"given":"Sandra","family":"Guerra","sequence":"first","affiliation":[]},{"given":"Paula","family":"Santos","sequence":"additional","affiliation":[]},{"given":"Jos\u00c8 C.","family":"Ribeiro","sequence":"additional","affiliation":[]},{"given":"Jos\u00c8 A.","family":"Duarte","sequence":"additional","affiliation":[]},{"given":"Jorge","family":"Mota","sequence":"additional","affiliation":[{"name":"University of Porto, Portugal"}]},{"given":"James F.","family":"Sallis","sequence":"additional","affiliation":[{"name":"San Diego State University, USA"}]}],"member":"179","published-online":{"date-parts":[[2003,2,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1097\/00005768-200009001-00004"},{"key":"atypb2","volume-title":"Young and Active?
