The primary goal of this investigation is to assess whether Solarplast (R) supplementation will improve recovery following heavy resistance exercise in active adults. The primary questions to be addressed are: Does Solarplast (R) decrease muscle damage and inflammation associated with heavy resistance exercise? Does Solarplast (R) reduce the decline in performance associate with heavy resistance exercise? Researchers will compare Solarplast (R) to a placebo (a look-alike substance that contains no active ingredients) to see if Solarplast (R) is effective at improving recovery. Participants will be asked to: Take Solarplast (R) or placebo daily for 4 weeks Visit the laboratory at least once per week to receive their supplement Report to the lab for 3 consecutive visits following supplementation to complete a heavy resistance training session and follow-up testing.
