About
Resveratrol, a compound found in red wine and dark-skinned grapes, will improve the function of mitochondria (energy producing components) within the leg muscles of moderate functioning older adults.
The investigators will look at the role Resveratrol plays in improving physical function by studying the connection of changes in mitochondrial function and changes in physical function.
Full description
An initial telephone screening indicated that the subject may be eligible to participate in the study. The first study visit ("Screening visit") will further determine if the subject is eligible to participate. Should the subject be eligible to participate in the study, the subject will be asked to participate in a daily resveratrol or placebo supplementation program for approximately 90 days. The subject will also be asked to return to the clinic for two additional assessment visits to monitor his/her safety and measure study results.
Details regarding the tests to be conducted during this screening visit and other study visits are described below. Visits will take place at the University of Florida Institute on Aging (IOA).
The Screening Visit is approximately 1.5 to 2 hours and will include:
Blood Draw: The subject is asked to fast before the appointment because blood will be collected during this visit. The investigator will collect approximately 2 tablespoons of blood. The purpose of this blood draw is to determine levels of certain compounds in the subject's blood that will help determine eligibility.
Questionnaires: The subject will be asked questions about medical history and medications as well as mood and will also be asked to complete a short test of memory and reasoning.
Physical Measurements: measurements of the subject's height, body weight, waist circumference, pulse, and blood pressure.
Physical Exam: A licensed health care provider will perform a brief physical exam to determine if it is safe to continue with the study. This exam will include a review of medical history, medications, and measurement of height, blood pressure, radial pulse, weight, and waist circumference.
Tests of physical performance: The subject will be asked to complete tests of physical ability that include:
Baseline Visit 1: Should the subject be eligible for the study, they will be asked to return to the clinic for the first baseline study visit. This visit is expected to take 2 to 3 hours and will include:
Measurement of pulse and blood pressure
Measurement of body weight and waist circumference
Collection of fasting blood samples
Questions about the subject's health
Tests of physical performance, including:
Physical Activity Monitor: The subject will also be asked to wear an armband physical activity monitor during a typical seven day period to assess baseline physical activity habits. The monitor will be returned at Baseline Visit 2.
Baseline Visit 2 will take approximately 2 hours and will include:
Measurement of pulse and blood pressure before procedure
Muscle Tissue Sample: The procedure to collect muscle samples will be performed by a licensed healthcare provider with experience conducting the procedure. The procedure includes numbing a small area on the thigh with a local anesthetic and then using a needle about the size of a pen to collect a small amount of muscle tissue approximately equal to the size of the head of a pencil eraser.
After the tissue sample is taken, the subject will receive detailed instruction on how to care for the incision site. Several follow-up phone assessments will be made inquiring about any problems that the subject may be experiencing related to the procedure.
Measurement of pulse and blood pressure after procedure
Randomization: Subjects who are eligible and safe to continue with the study, will be randomly assigned to one of three conditions: (1) resveratrol (1000 mg/day) (2) resveratrol (1500 mg/day) or (3) placebo (vegetable cellulose).
The subject will be provided with a supply of the study drug capsules of at least 30 days and will be asked to return any remaining study drug capsules to the clinic at the next appointment. Subjects will be asked to orally consume one study drug capsule following each main meal (i.e. breakfast, lunch and dinner) with a glass of water.
30-Day & 60-Day Visits last approximately 1 hour and include:
90-Day Visit 1 is similar to the Baseline 1 visit and will last approximately 2-3 hours. This visit includes:
Measurement of pulse and blood pressure
Measurement of body weight and waist circumference
Collection of fasting blood samples
Update medical history and ask questions about any adverse experiences the subject may have had since last visit
Counting of any remaining study drug capsules that were not taken since last visit
Tests of physical performance, including:
The subject will receive an armband physical activity monitor to wear for seven days, and will be asked to return this monitor at the 90-Day Visit 2.
90-Day Visit 2 will be similar to the Baseline 2 visit and will last approximately 1.5 to 2 hours.
Follow-Up 10-Day & 30-Day Visits are approximately 30 minutes to 1 hour
