Summary

The knowledge gap on sedentary behavior and sedentary breaks includes whether detrimental effects of sedentary behavior can be fully attenuated by 1.) sedentary breaks 2.) physical activity or 3.) both combined. Specifically, when breaking sedentary time which physical activity pattern- and intensity modifies the negative effects of sedentary behavior on glucose- and lipid metabolism? This lack of quantitative evidence calls for prospective experimental studies investigating the physiological and biological impacts of sedentary behavior, as well as the effectiveness of different strategies to reduce sedentary time. Thus, quantifying effects of the intensity, frequency, volume of sedentary breaks and/or physical activity on predefined outcomes is of importance.

Aims:

Our primary aims are to investigate the effects of breaking up sedentary time on glucose- and lipid metabolism and thus examine whether physical activity intensity breaks during sedentary breaks matter. Specifically, the aims of the PhD-project are to provide knowledge on the following questions:

• How does high- or low physical activity intensity sedentary breaks acutely influence glucose- and lipid metabolism under iso-caloric conditions?
