Background: Public health research on sedentary behavior (SB) in youth has heavily relied on accelerometers. However, ithas been limited by the lack of consensus on the most accurate accelerometer cut-points as well as by unknown effectscaused by accelerometer position (wrist vs. hip) and output (single axis vs. multiple axes). The present study systematicallyevaluates classification accuracy of different Actigraph cut-points for classifying SB using hip and wrist-worn monitors andestablishes new cut-points to enable use of the 3-dimensional vector magnitude data (for both hip and wrist placement).
Methods: A total of 125 children ages 7–13 yrs performed 12 randomly selected activities ...

Beginning with the work of Webb (1969), a line of research has developed attempting to explain how the socialization experiences of children and adolescents help transform their attitudes toward play. In Webb's view, the transformation to a state of being "professionalized" has occurred when an emphasis on equity and fairness, which are pronounced at earlier stages of development, has been replaced by a focus on winning. The body of research that hasdeveloped from this original formulation has consistently identified age and gender differences (Loy , Birrell, & Rose, 1976; Maloney & Petrie, 1972; Mantel & VanderVelden, 1971) in play attitudes, with males being more highly professionalized than ...
