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.

Interventions

DIETARY_SUPPLEMENT

Blueberry Plus Exercise (BB-EX)

Pre-packaged blueberry powders are from U.S. Highbush Blueberry Council and are packaged in sealed single-serving packets (18 g/packet) to prevent exposure to light and moisture. All supplement packets are stored under refrigeration until distribution to study participants. Participants will be asked to increase physical activity through a weekly supervised exercise class and increasing baseline daily step counts gradually over the course of the intervention.
