Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

About 32 healthy subjects are subjected to 4 weeks of exercise, 4 weeks of washout and 4 weeks of sedentary life style, randomization decides whether they start with exercise or with being "couch potatoes". All participants are also randomized to also consume 150 g of blueberries on exercise days or not. The exercise is constituted of 5 km running 5 days a week during the 4 week period. The exercise period and the "couch" period are started and ended with a 5 km run at maximal speed and the fasting blood samples for cardiovascular risk factors are measured before and after this run, ie 8 times in total.
