Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

After pre-testing, participants will be randomized to supplement with resveratrol (500 mg) or placebo for 14 weeks. All participants will complete two 6-week blocks of supervised strength training (full body, 3 days/week); each block will be followed by one week of testing.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Resveratrol (RSV) group

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.

Group Type EXPERIMENTAL

Resistance training

Intervention Type BEHAVIORAL

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.

Intervention Type DIETARY_SUPPLEMENT

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.
