Strength Training and Resveratrol

Summary

The main goal of this study is to find out if supplementing with resveratrol improves skeletal muscle adaptations to strengthening exercise (resistance training or strength training) in adults age 60+, and to determine whether circulating vehicles of inter-organ communication (extracellular vesicles) and their cargo might help explain those responses. The investigators will also examine whether resveratrol supplementation improves blood vessel function and cognitive function (brain health) in response to strength training.

Detailed Description

After screening and providing informed consent, participants (healthy older adults, age 60+, minimally active) will be familiarized with the procedures and undergo pre-testing. After pre-testing, participants will be assigned to supplement with resveratrol or placebo (double-blinded) daily while undergoing a strength training intervention. Strength training will be performed 3x/week for two 6-week blocks, and each visit will be supervised by a member of the study team. An additional week of testing will follow each of the two 6-week blocks.
