Common Questions
I have been told to avoid
electrolyte mixes with sugar. Is this
problem with Perform ‘N Win?
It
is true that supplements containing large amounts of sugar should be avoided
when using that supplement before, during or after exercise to replace sweat
losses. This kind of supplement may
cause sugar highs and lows. However, a
supplement without any glucose (a simple sugar) will not be absorbed
efficiently. There are transporters in
the small intestine that carry sodium, potassium and water, with glucose across
the intestinal wall into the bloodstream.
The amount of carbohydrates in PNW (approximately 3%) is balanced to
ensure rapid absorption of sodium, potassium, and water (for comparison, Gatorade
has 6% carbohydrates to promote electrolyte transport in humans). The rapid absorption of the PNW supplement
has been confirmed by research at the Equine Research Centre, by using tracers
to follow the absorption of sodium and potassium. The ingestion of up to 3 ounces of PNW in ¾ gallon of water will
not cause sufficiently large increases in plasma glucose to get a sugar
high. It is recommended that during
exercise, not more than 2 ounces in ½ gallon water be administered at once.
Why can’t you make it into a
paste?
Some supplements are sold as a
salt paste. This highly concentrated
material in the stomach will empty much more slowly than water. It may take twice as long to be emptied into
the intestine an the recovery process is delayed considerably. Also some pastes are manufactured in a corn
syrup (high sugar) base and as mentioned above, high sugar intake is not
recommended for the horse during exercise.
These pastes also cause dehydration of body fluids unless given with
adequate amounts of water.
We do not recommend using salt
pastes during exercise as they disturb the fluid balance of the horse. This has been confirmed by a team in Sweden
(Nyman et al.) doing research on endurance horses during competition. They recommend against using salt pastes
before and during exercise.
Can I make my own recipe at
home for less money?
Yes, you can. However, the ration of salts, the form of
salts and the proportions of salts vs. Carbohydrates is important for designing
a supplement that will work optimally during
exercise. The PNW resulted in increased
time-to-fatigue (23% longer exercise duration at a constant speed) when used on
horses under controlled treadmill conditions.
The study also showed rapid uptake and distribution into the blood and
of K+ into the blood cells and skeletal muscle. Controlled tests have found this supplement
to be effective at quickly restoring water and salt losses in exercising
horses.
Powders in general, and PNW in
particular, ounce for ounce are about 10% of the cost of most commercially
available pastes when administered for a given ride distance.
What type of horse is this
supplement suited for?
All horses undergoing prolonged
(2 hour or more) exercise, including training and long walks in warm weather
sufficient to cause sweating. PNW is
designed to be fed on a per hour of exercise basis. This makes it ideally suited to the performance horse. No guessing is needed about your horse’s
weight where the dose of the supplement is based on body weight.
How is weight loss related to
performance decrements?
The amount of weight lost during
exercise is predominantly due to sweat losses.
If a 450 kg (1000 lb.) horse loses 14 kg (30 lbs), this means that about
14 L of sweat has been lost or a 3% body mass loss has occurred. Recent research show that even a 3% body
mass loss can have a negative effect on performance in horses. A 3% decrease in body mass is equal to about
a 5% decrease in body water ( 5% dehydration).
At the Race of Champions, horses that lost more fluids (body mass) in
the early part of the ride finished at slower speeds than the horses that
maintained their body mass. In other
words, a high sweat loss that is not replaced early in the ride results in a
slower ride speed (poorer performance).
It is important to keep water and electrolytes going into the horse,
even during the early part of the endurance ride if a strong finish is desired.
Isn’t water sufficient? Why do I have to add electrolytes?
Intake
of water alone will actually dilute the remaining fluids in the horse,
decreasing the concentrations of sodium, potassium and chloride in the
blood. This dilution can be a serious
health concern because it leads to an imbalance of electrolytes and increases
the time it takes for full rehydration and electrolyte replacement. It may also reduce the thirst response,
which is affected by the sodium concentration in the blood. The composition of PNW with electrolytes and
carbohydrates ensure that rehydration occurs rapidly, and the bloodstream is quickly
absorbing the water and electrolytes it needs to recovery. The Na is retained in the bloodstream and
the rest of the extracellular fluid where it retains water. The K+ helps retain water in the
muscle and the rest of the intracellular fluids. Testing has even confirmed that the K+ tracer is given with water. The maintenance and restoration of K+ and water into the muscle is critical for
optimal and continued performance.
Do I need to give electrolyte
supplements during the week when training?
If your work-outs cause sweating
that last for more than one hour each day, then using PNW in the water after
your work-outs will aid in faster recovery.
PNW is not designed as a daily all-purpose electrolyte supplement, but
many like to use it during the week as well as during competitions and training
to maintain consistency.
Can I give PNW in any other
manner?
Yes,
as long as you know the hydration status of your horse. If you prefer to administer the PNW as a
slurry or paste by syringe directly into the mouth, only do so after the horse
has had a good drink. PNW can be given
in the feed in the morning for pre-loading.
We know of one endurance rider that makes PNW “cookie” to give his horse during the endurance
competitions. As such, they can be
useful rewards for the horse AFTER the horse has had a drink of water. They could also be used at home to train the
horse to drink.
Do I need to give my horse
electrolytes on short rides (< 30 miles ) ?
The answer to this question
depends on the conditions. If it is
hot and humid, then giving your horse PNW will help the horse during exercise
and to help enhance recovery. Even
though the distance may seen short, if the speed is higher, or it is hot and
humid, the horse can still lose more than 20 L (5 gallons) of water.
Will horses get enough salt
from a salt block to replace the sweat losses?
If your horse is sweating more
than 2 hours a day, then it is unlikely to get enough salt in a short period of
time. Salt blocks are made for
cattle. The horse may not be able to
lick enough salt to replace the losses.
This is frequently why you see horses chewing or scraping their teeth on
the salt block to get more. Providing
free choice loose salt can help avoid this problem. Also, some of the blocks contain other minerals and
substances. If the horse licks or chews
the block enough to satisfy the sodium requirements, it may be getting too much
of the other minerals that are not lost in sweat.
Isn’t it bad to give the horse
electrolytes during the week? Don’t we
make the horse lazy in saving electrolytes?
Electrolytes
cannot be “saved” or “stored” for long periods. The only way we know of
to “store” electrolytes is to put them into the g.i. tract, with water,
before exercise. There is no evidence
to show that giving a horse electrolytes during the week makes him “lazy”
during the endurance ride. In fact, the
opposite may occur. If the horse is
lacking in electrolytes from the hours of training, it may be in a fluid and
electrolyte deficit before the ride even starts. The loss of water and electrolytes is an obligatory result of
heat dissipation. These losses, if not
replaced, can negatively impact on the performance and health of the animal.
