Study Summary
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.
Primary Outcome
Change in carotid-femoral pulse wave velocity will be assessed using applanation tonometry, (SphygmoCor Pulse Wave Velocity System)
Interventions
- DIETARY_SUPPLEMENT Blueberry Plus Exercise (BB-EX)
- DIETARY_SUPPLEMENT Blueberry Placebo Plus Exercise (P-EX)
