Brief Summary
Individuals who participate in regular physical exercise possess a lower prevalence of cardiovascular risk factors such as hypertension, type 2 diabetes, obesity and hypercholesterolemia, and aerobic exercise is therefore considered an important adjuvant therapy in risk factor modification and to promote health. The main focus of the present study is therefore to detect how rapid it is possible to increase aerobic capacity with interval running exercise. The hypothesis is that it is possible to improve maximal oxygen uptake faster when increasing training frequency. The total gain in maximal oxygen uptake will however be the same between the two groups when they have performed the same amount of training
