One of the key tenets of exercise physiology recently got
turned on its head. For years
exercise physiology students were taught that improving oxygen delivery to
muscles was one of the keys to improved athletic performance and work capacity.
It was established that oxygen delivery to muscles could be
improved through several different processes such as increased lung
capacity allowing lungs to take in larger quantities of air and oxygen; the heart
becoming stronger allowing it to pump more blood to the muscles which carries
oxygen; or increasing the amount of red blood cells and hemoglobin in the blood
which allows the blood to carry more oxygen to the muscles. But It
had been assumed that the fundamental amount of energy a human can create using
a given amount of oxygen remained constant so all improvements came from the
ability to deliver more oxygen to the muscles.
A 2009 study shattered this assumption! The study (http://www.ncbi.nlm.nih.gov/pubmed/19661447
) looked at 8 men who were given either
2 cups of beet root juice or 2 cups of black currant drink as a placebo for 6
consecutive days and completed a series of moderate-intensity and
severe-intensity exercise tests on the last 3 days. Something amazing happened: the men taking the beet root juice showed
the ability to do the same amount of work with 19% less oxygen consumption and
their time-to-exhaustion was extended by 15.7% compared to the placebo group! Before this study there was no known
substance that could increase energy creation based on a given amount of oxygen
delivery! To see a great video

Since this time many studies have confirmed the positive
impact beet juice can have on human physiology, and several companies have
developed beet products based on beets grown to maximize their content of
Nitrates which are responsible for most of the benefits! Nitrate aids your body in producing more
Nitric Oxide which helps to open your blood vessels prior to and during
exercise. This allows you to get more
energy from a given amount of oxygen so your muscles feel stronger for longer
and your time to exhaustion increases! This
can allow you to train harder for a longer period of time!
There are other substances such as the amino acid arginine
that can increase nitric oxide levels but this requires a complex process. However Nitric Oxide can be formed from
dietary nitrate in a much simpler process that does not require any co-factors
like Nitric Oxide creation from arginine.
Beetroot Health
Benefits
Beetroot is an excellent source of iron and folate, both of
which are key nutrients for everyone but particularly woman!
Helps lower blood pressure
Contain betaine, which has been shown to have significant
anti-cancer properties and is effective in inhibiting the formation of cancer
cells and in particular colon and stomach cancer.
Helps relieve constipation
Helps detoxify the liver
How do I get the
benefits?
If you like beets eating them can provide the same benefits
as beet juice and cooking them does not reduce the benefits either! If you want the maximum benefits there are
now several companies making beet root powders that mix easily with water or
juice, and several of these companies use specially grown beets that have
extremely high and consistent levels of Nitrate. There are several companies including
“Beet Elite” https://neogenissport.com/
that produce powders available in black cherry flavor for those who do not like
the taste of beets. You can also mix
the powder into a smoothie with frozen berries.
It is best to ingest it an hour before exercise.
