Effects of Exercise With or Without Blueberries on Cardiovascular Risk Markers
A study testing Blueberries in people with Risk Factors Cardiovascular Disease and Inflammation, run by University Hospital, Linkoeping at 1 site in Sweden.
Trial summary
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. Read more about this study

About this study
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.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
markers for cardiovascular disease (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
