Sedentary behavior (SB) is a major contributing factor to obesity and significant morbidity and mortality in adolescence and into adulthood, yet measuring SB is difficult. The purpose of this study was to assess the degree of construct validity of the ActiGraph GT3X+ inclinometer function and accelerometry metrics in objectively measuring SB and physical activity in young adult university students while performing semi-structured activities: lying, sitting, reading, playing seated video gaming, video watching, seated conversation, standing, stationary biking, and walking. These nine activities were objectively assessed using inclinometry and four output metrics from the ActiGraph based on the axis used to …
