Summary:

      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.
