Nilsson, Andreas; Anderssen, Sigmund A.; Andersen, Lars Bo; Froberg, Karsten; Riddoch, Chris J.; Sardinha, Luis B.; Ekelund, Ulf (Peer reviewed; Journal article, 2008-02-03)To examine differences in levels of physical activity (PA), time spent at moderate-to-vigorous intensity PA (MVPA) and time spent sedentary between and within days in children from four European countries, 1954 9 - and ... -
Comparison of equations for predicting energy expenditure from accelerometer counts in children
Nilsson, Andreas; Brage, Søren; Riddoch, Chris J.; Anderssen, Sigmund A.; Sardinha, Luis B.; Wedderkopp, Niels; Andersen, Lars Bo; Ekelund, Ulf (Peer reviewed; Journal article, 2008-01-14)Several prediction equations developed to convert body movement measured by accelerometry into energy expenditure have been published. The aim of this study was to examine the degree of agreement between three different ... -
