Strength Training and Resveratrol
Sponsor: Texas Tech University
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.
Official title: Resveratrol-mediated Changes in Extracellular Vesicle microRNA Cargo as a Novel Contributor to Resistance Training-induced Skeletal Muscle Adaptations in Older Adults

Interventions
Resistance training
After pre-testing, participants will perform full-body strength training three times per week for two 6-week blocks. The acute program variables (sets, repetitions, training frequency) will follow a non-linear periodized, progressive design consisting of muti-joint and single-joint exercises. Exercise stress will be varied by using different exercises and loads. The two training blocks will be separated by a mid-intervention testing week, allowing for the study team to monitor participants' progress, communicate progress to participants to promote adherence, and adjust target loads as appropriate for the second half of the intervention. An additional testing week will follow the second 6-week block.
Resveratrol 500 mg oral once daily.
Participants will be randomized to consume resveratrol (500 mg) daily for 14 weeks (two 6-week blocks of resistance training \[supervised, full-body, 3 days/week\] + one testing week \[3 days\] following each block) after the pre-testing period. Participants will be provided with 7 days' worth of supplements at a time in pre-filled pill boxes. Pill boxes will be refilled weekly and adherence monitored.
Placebo
Participants will be randomized to consume placebo capsules (cellulose, visually identical to resveratrol capsules) daily for 14 weeks (two 6-week blocks of resistance training \[supervised, full-body, 3 days/week\] + one testing week \[3 days\] following each block) after the pre-testing period. Participants will be provided with 7 days' worth of supplements at a time in pre-filled pill boxes. Pill boxes will be refilled weekly and adherence monitored.
