PERFORMANCE NUTRITION GLOSSARY
Adrenal glands
- A pair of ductless glands located above the kidneys.
Through hormonal secretions, the adrenal glands regulate
many essential functions in the body, including
biochemical balances that influence athletic training
and general stress response.
Adrenalin
- Popular term used to describe the various hormones
secreted by the adrenal glands in response to stress.
Aerobic
- literally "with oxygen". Commonly used to describe an
exercise intensity where muscles can use oxygen to
convert glucose and fat into energy. Aerobic training is
carried out at a comfortable pace to ensure that the
muscles have sufficient oxygen available.
Anabolic
- Pertaining to the putting together of complex
substances from simples ones, especially to the building
of muscle protein from amino acids.
Anaerobic
- literally "without oxygen". A high-intensity energy
system where the muscles lack sufficient oxygen to
successfully burn fuel, resulting in the production of
lactic acid. Anaerobic exercise is very intense and can
only be sustained for short periods of time.
Alpha-L-polylactate
- CytoSport's proprietary formula that provides a
long-lasting source of carbohydrate energy and buffers
lactic-acid production in the working muscles. The
principal ingredient in Cytomax.
ATP
- Adenosine tri-phosphate. A high energy phosphate
molecule required to provide energy for cellular
function. The energy source your muscles use for short
bursts of power.
Amino acids
- Nitrogen-containing compounds that are the building
blocks of proteins. There are 22 different amino acids
from which every protein in the body is made up of.
There are nine so-called essential amino acids that are
not manufactured by the body and must come from the
diet.
Bonk
- depletion of glycogen and blood sugar while
exercising. Symptoms include a dramatic reduction in
performance and feeling disoriented and weak. Occurs
when not using enough CytoSport.
Carbohydrate
- Sugars and starches that are the most efficient source
of food energy. Stored in the muscle and liver as
glycogen and in the blood as glucose.
Catabolic
- The aspect of metabolism which converts nutrients or
complex substances in living cells into simpler
compounds with the release of energy, such as cortisol
catabolizing muscle protein into glucose for quick
energy.
Cell
- The smallest structural unit of living material.
Creatine
- The fuel source for ATP, an energy system used for
short bursts of power. Dehydration - The abnormal
depletion of body fluids. Results in a severe decline in
athletic performance and can lead to life-threatening
circumstances.
Electrolytes
- Minerals (e.g - sodium, potassium, magnesium, calcium)
that regulate bodily functions. Small amounts are lost
in sweat and need to be replaced through the use of
energy drinks like Cytomax.
Enzymes
- Proteins necessary to bring about bio-chemical
reactions.
Fat
- A type of caloric energy found in food, essential for
a variety of body functions including organ protection,
hormone balances, and as a long-lasting fuel source for
low-intensity exercise. Dietary fats are classified as
saturated (animal flesh, butter, margarine, processed
and fried foods) and unsaturated (vegetable oils).
Unsaturated fats are the preferred food for health
reasons.
Gastric emptying
- The action of the stomach contents emptying into the
small intestine. Most energy drinks and supplements are
absorbed into the body via the intestine. The
carbohydrate content of energy drinks affects their
gastric emptying rate. Recommended carbohydrate content
is 7% (one scoop of Cytomax in a 500ml bottle = 7%),
which allows a gastric emptying rate nearly equal to
that of waters.
Glucose
- The form in which all carbohydrates are used by the
body for energy.
Glucosamine
- The basic molecule that comprises your connective
tissue. Glucosamine helps you make new proteoglycans,
enabling your worn connective tissue to become smooth
and resilient. The principal ingredient in CytoSport's
Joint Matrix.
Glycogen
- The storage form of glucose found in the liver and
muscles.
Gram
- A measurement of weight equal to about 1/28th of an
ounce.
Hormone
- A chemical substance that is secreted into body fluids
and transported to another organ, where it produces a
specific effect on metabolism.
Hypoglycemia
- A deficiency of sugar in the blood caused by too much
insulin or too little glucose.
Insulin
- A hormone secreted by the pancreas that helps regulate
carbohydrate metabolism.
Kilogram
- A measurement of weight equal to about 2.2 pounds.
Lean body mass
- Body weight minus body fat; primarily muscle, bone and
other non-fat tissue.
Medium chain triglycerides
- known as the "fatless fat", these fat molecules are
easily mobilized in the bloodstream to provide
long-lasting energy, rather than being stored as fat.
They also help limit the conversion of excess
carbohydrates into fat. One of the "Lean Lipid"
ingredients in Muscle Milk.
Metabolism
- The chemical and physiological processes by which the
body builds and maintains itself and by which it breaks
down food and nutrients to produce energy.
Minerals
- Organic substances needed in the diet in small amounts
to help regulate body function.
Mitochondria
- Specialized subcellular structures located within body
cells that contain oxidative enzymes needed by the cell
to metabolize foodstuffs into energy sources.
Organic
- Being composed of, or containing matter of plant or
animal origin.
Phosphatidylserine
- a custom-engineered phospholipid extract that blunts
the exercise-induced spike of the adrenal hormone
cortisol into the bloodstream, reducing its catabolic
effects. One of the active ingredients in MusclEnergy.
Phospholipid
- A fat in which one fatty acid is replaced by
phosphorus and a nitrogenous compound.
Pituitary gland
- Small gland in the brain which secretes substances
necessary for basic life processes, such as growth.
Protein
- The major structural component of all body tissue;
necessary for muscular growth and cellular repair.
Proteins are also a functional component of enzymes,
hormones, etc. Used for energy only when carbohydrates
and fats are not available.
Stress
- Any real or perceived adverse stimulus, physical or
psychological, that tends to disturb an individuals
homeostasis.
Triglyceride
- The storage form of fat consisting of three fatty
acids and glycerol.
Vitamins
- Organic compounds that function as metabolic
regulators in the body. Classified as water soluble or
fat soluble. Vitamins cannot be manufactured by the body
and must be obtained through diet or supplements.
VO2 Max (Maximal oxygen consumption)
- The highest volume of oxygen a person can consume
during exercise. Often used as a predictor of potential
in endurance sports.
