Exercise and Arterial Modulation in Youth

The project is designed as a large scale, cross-sectional study. The aim of the study is to investigate the association of micro- and macrovascular function with physical fitness and body composition in primary school children.

The investigators will examine whether physical fitness, body composition and blood pressure differently affect large and small arteries in young children. Furthermore, the investigators will examine whether pulmonary dysfunction is associated with vascular disorders and if subcutaneous advanced glycation endproducts (AGE's) mediate some of the vascular alterations observed.

Inclusion Criteria:

• primary school children aged 6-8 years who can participate in physical education lessons with written consent from their parents.

Exclusion Criteria:

• children with a medical certificate that prohibits physical exercise with no consent from their parents.
