Official title
Effects of Blueberry Consumption on Vascular Function, Physical Activity, and Cognition in Sedentary Older Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recent evidence suggests that increased berry intake results in a variety of health benefits, across multiple health domains. This 3-month randomized, double-blind, placebo-controlled trial assess the effects of combining daily blueberry intake with weekly exercise (BB-EX) on cardiovascular function, as well as physical activity and cognitive function, in sedentary older adults (\>60 years). We will compare these effects to the same outcomes with a control group consuming a blueberry placebo (P-EX) at 0, 4, 8 and 12 weeks.
