Carbohydrates provide the best and most
readily available source of energy for your
body during intense training or competition
and are vital for keeping your muscles and
mind operating at peak performance. Just as
recovery and muscle repair are important,
carbohydrate intake ensures that event
fatigue does not set in. Training and
post-exercise nutrition are essential for
consistent performance, but to prevent and
delay event fatigue carbohydrate
replenishment is equally important.
Carbohydrate loading helps endurance
athletes to avoid "hitting the wall."For
the past two decades, research has confirmed
that carbohydrates ingested during exercise
can improve endurance performance. During
activity lasting longer than 60 minutes
glycogen levels begin to diminish and there
is a progressive shift from muscle glycogen
over to blood glucose as the body's primary
fuel source. When muscle glycogen levels are
low the consumption of carbohydrates serve
to maintain proper levels of blood glucose
and delay the onset of fatigue. In addition
to this system, carbohydrate intake also
exerts its benefits at higher intensities of
exercise by delaying and/or preventing
muscle glycogen depletion (otherwise known
as glycogen sparing).
Depending on the chemical composition and
the rate of digestion and absorption,
carbohydrates differ in their ability to
raise blood glucose level. Thus, foods
containing the same quantity of
carbohydrates can differ markedly in effects
on raising the blood glucose level. The
glycemic index (GI) concept was introduced
as a means of classifying different sources
of carbohydrates that are present in the
diet. This method was assumed to apply to
foods and drinks which primarily deliver
available carbohydrates (available refers to
completely digestible). Accordingly, low-GI
carbohydrates are classified as those which
are digested and absorbed slowly and which
lead to a low glycemic response, whereas
high-GI carbohydrates are rapidly digested
and show a high glycemic response.
Athletes have been cautioned that eating
carbohydrate foods in the hour before
exercise may alter exercise metabolism by
stimulating insulin production, which in
turn increases the rate at which the muscles
burn carbohydrate. As a result of this
faster rate of carbohydrate oxidation, blood
glucose levels may actually fall (a
condition known as hypoglycemia) shortly
after exercise begins. Many guidelines for
athletes now recommend that endurance
athletes choose low glycemic carbohydrate
foods for their pre-event or pre-training
meals. The low-glycemic food does not cause
a high rise in insulin, so muscle burns more
fat, preserves their stored sugar supply and
can be exercised longer.
Carbo Booster contains Isomaltulose, a
novel slowly digestible sugar sweetener,
which can help reduce both the glycemic and
insulinemic response in foods and beverages.
Isomaltulose is absorbed more slowly and
metabolized slower than other sugars, is
tooth friendly and well-tolerated without
side effects. Isomaltulose is the first slow
digestible sugar that, like sucrose,
delivers both glucose and fructose but
results in a low sugar and low blood insulin
response.
