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.
