Study Details

The purpose of this clinical trial is to determine how certain food items affect oxidative stress, inflammation, and performance recovery from exercise induced muscle damage in a resistance trained population. The main questions The investigators aim to answer are the following: * Do Haskaps speed the recovery of oxidative stress and inflammation markers after an intense lower body workout in resistance trained adults? * Do Haskaps speed the recovery of performance measures after an intense lower body workout in resistance trained adults? * The data collected in this investigation may also be used to ask additional questions not yet identified. For example, the investigators may use the stored samples to evaluate how the blood metabolites of participants differ before and after intense exercise. These additional questions are called secondary analyses. Please note that no genetic analysis will be conducted and racial and ethnic differences among participants will not be used in any secondary analyses. Researches will compare Haskap juice to a color, flavor and carbohydrate matched placebo to see if Haskaps speed recovery in inflammation, oxidative stress and performance. * Participants will be asked to drink either Haskap juice or placebo and follow a low polyphenolic diet * Participants will perform an intense resistance workout * Participants will have their blood drawn before and after the workout * Performance will be analyzed at 24, 48 and 72 hours after the workout

Arms

  • Placebo Comparator: Placebo Control
    The placebo supplement will have no polyphenol content and will be carbohydrate-matched to the experimental group. A twice daily dose (10-12 hours apart) will be consumed for 11 days.
  • Experimental: Haskap
    The haskap supplement will consist of a haskap berry smoothie. A twice daily dose (10-12) hours apart will be consumed for 11 days.
