Hur aktiv är befolkningen – egentligen? Håller dagens rekommendationer?

Abstract

Successful public health interventions demand a clear understanding of how, and to what extent, people are physically active. Physical activity is, however, dif. cult to measure accurately. We have tested various methods. New insights into how, and to what extent, people are active were achieved. The data raised many issues regarding lifestyle physical activity. Is it the total time spent in moderate intensity that is important, or the achievement of continuous bouts? What is the implication for the current recommendations? There is obviously a need for a discussion about the current recommendations. A better understanding of the objective measurement of lifestyle physical activity is needed to clarify how, and to what extent, people are active.
