     Summary:   
         New research has found that olive fruit water, a by-product   
         typically thrown away during olive oil production, could have   
         exercise benefits.   
      
         The study tested olive fruit water during exercise and found it   
         had positive effects on several key markers of running performance.

   FULL STORY   
   ==========================================================================   
   New research has found that a natural by-product of olive oil production   
   could potentially have antioxidant benefits and support exercise.   
      
      
   ==========================================================================   
   The study, led by nutrition researchers at Anglia Ruskin University   
   (ARU) and published in the journal Nutrients, is the first to examine the   
   benefits of natural olive fruit water for recreationally active people.   
      
   Olive fruit water is a waste product derived from producing olive   
   oil. Olives contain polyphenols which have antioxidant properties, and   
   a commercially available olive fruit water product, called OliPhenolia,   
   contains a number of phenolic compounds and is particularly rich in   
   hydroxytyrosol.   
      
   The first study into its potential benefits for people who exercise   
   involved 29 recreationally active participants who consumed either   
   OliPhenolia or a placebo, matched for taste and appearance, over 16   
   consecutive days, and it found positive effects on several key markers   
   of running performance.   
      
   OliPhenolia consumption improved respiratory parameters at the onset   
   of exercise as well as oxygen consumption and running economy at lower   
   levels of intensity (lactate threshold 1).   
      
   Respiratory parameters at higher intensity (lactate threshold 2) were   
   largely unaffected, but perceived exertion -- how hard participants   
   thought their body was working -- was improved, as was acute recovery   
   following incremental exercise.   
      
   Lead author Dr Justin Roberts, Associate Professor in Health & Exercise   
   Nutrition at Anglia Ruskin University (ARU), said: "For a long time I've   
   been interested in the exercise benefits of polyphenols, such as those   
   derived from cherries and beetroot. To gain similar benefits from olives   
   you would have to consume large quantities daily, which isn't realistic,   
   so we were keen to test this concentrated olive fruit water.   
      
   "Like olive oil it contains hydroxytyrosol, but this olive fruit water is   
   a sustainable by-product. It's typically thrown away during the production   
   of olive oil, and we found a company in Italy -- Fattoria La Vialla,   
   a biodynamic farm in Tuscany -- who decided to turn this waste water   
   into a dietary supplement.   
      
   "Ours is the first study to investigate the use of this olive fruit water   
   in an exercise setting and we found that 16 days of supplementation   
   could have a positive influence on aerobic exercise, most notably at   
   submaximal levels.   
      
   "We found that reduced oxygen cost and improved running economy, as well   
   as improvements in acute recovery, indicate it could potentially benefit   
   those who are undertaking regular aerobic exercise training.   
      
   "We now intend to carry out further research at Anglia Ruskin University   
   to corroborate these findings. We are also looking to investigate   
   whether this product can be used for marathon training and recovery,   
   as well as test its effectiveness in suppressing inflammation associated   
   with exercise."  Dr Roberts carried out the work with researchers Jorge   
   Pinto and Joe Lillis.   
      
   The research was funded by Fattoria La Vialla, Arezzo, Italy. The funders   
   had no role in the design of this peer-reviewed study; in the collection,   
   analysis or interpretation of data; in the writing of the manuscript;   
   or in the decision to publish the results.
