Abstract
<jats:sec sec-type="background"><jats:title>Background:</jats:title><jats:p>Evidence suggests that a substantial proportion of children meet guidelines for sufficient physical activity, but also exceed TV guidelines. Health-related consequences of this combination are unknown.</jats:p></jats:sec><jats:sec sec-type="methods"><jats:title>Methods:</jats:title><jats:p>843 children, (age 10-11 y), were surveyed for health-related fitness [endurance performance (20 m MST), skinfolds, waist girth], daily TV and moderate-to-vigorous physical activity (MVPA). Children were grouped using daily TV (≤ 120 min) and MVPA (≥ 60 min) guidelines: hiTV-hiMVPA/“technoactives”’; hiTV-loMVPA/“screenies”; and loTV-hiMVPA/“sporties.” Groups were compared on health-related fitness measures.</jats:p></jats:sec><jats:sec sec-type="results"><jats:title>Results:</jats:title><jats:p>There was a trend (<jats:italic>P</jats:italic> = 0.07) towards higher girls’ skinfolds among “screenies” than “sporties.” Boys’ waist girths were higher among “technoactives” than “sporties” (<jats:italic>P</jats:italic> = 0.008). Male “technoactives” outperformed “screenies” on the 20 m MST (<jats:italic>P</jats:italic> = 0.03). Female “sporties” (<jats:italic>P</jats:italic> = 0.004) and “technoactives” (<jats:italic>P</jats:italic> = 0.0002) outperformed “screenies” on the 20 m MST.</jats:p></jats:sec><jats:sec sec-type="conclusions"><jats:title>Conclusions:</jats:title><jats:p>“Technoactives” were no different than “sporties” on endurance fitness but exhibited less favorable fat distribution among boys. Overall, “screenies” exhibited the least favorable health profiles.</jats:p></jats:sec>
