Why was this study done? To investigate if resveratrol-based polyphenol supplement (Vivix) for 4 weeks can attenuate exercise-induced muscle damage symptoms and facilitates performance recovery. What did the study find? Daily supplementation of Vivix for 4 weeks in 22 men and women attenuated soreness caused by the exercise-induced muscle damage, which may help recovery…
Why was this study done? Supplementing with nutrients that support nitric oxide (NO) production are known to help improve the efficiency of muscles in both athletes and non-athletes. However, when to start supplementation and how much to supplement is an unanswered question. What did the study find? This study found that supplementing with a natural…

Why was this study done? “Sports Anemia” is a phenomenon that occurs during strenuous exercise, it is especially prevalent in women. This study was designed to investigate supplemental iron as a way for avoiding anemia in athletes. What did the study find? Supplementing with iron (either 9mg or 19 mg of ferrous fumarate) had no…
Why was this article written? Athletic events today are so competitive that the difference between gold and silver medals is often measured in hundredths of seconds. Elite athletes must push themselves as never before to the limits of physical endurance, and now more than ever nutrition is one of many factors which may be optimized…
Why was this study done? Athletes need optimal nutrition in order to perform at their best. This study analyzed the diets of current elite male and female Nordic skiers. What did the study find? The study found that this group of elite athletes were consuming enough calories, but not enough carbohydrates, and too much fat…
Why was this study done? Iron depletion is common female athletes and may be common in male athletes. Reasons for lowered iron status in athletes are unknown, but hypothesized to be a result of red blood cell destruction, or increased iron uptake by myoglobin and other enzyme systems. This study was designed to see the…
Why was this study done? Proper hydration is of key importance to athletes and is closely tied to athletic performance and time to fatigue. Water is a good hydration source, but hydration occurs faster when electrolytes (primarily sodium) and carbohydrates are included in drinks. This study was designed to investigate varying concentrations of sodium and…
Why was this study done? Astronauts commonly experience dehydration during long flights. It is important to understand the role of rehydration formulas and their ability to prevent dehydration (maintenance of plasma volume). This study was designed to better understand the role of differing concentrations of rehydration formulas on dehydrated subjects. What did the study find?…
Why was this study done? Glycogen (short-term glucose storage) replenishment is of utmost importance to competitive athletes as it is closely related to endurance and time to fatigue. It has long been known that consuming carbohydrates following an exercise bout was a successful strategy for replenishing glycogen. This study was designed to understand the role…
