Chapter 15: Supplementation Flashcards
Vitamins
Organic compounds essential for normal growth and nutrition.
Minerals
Elements in food that the body needs to develop and function.
Dietary Supplement
A product containing one or more dietary ingredients that is intended to supplement a person’s nutrition plan.
Dietary Ingredient
A vitamin, mineral, herb, botanical, or amino acid used to supplement a nutrition plan to increase total dietary intake of ingredients.
Herb
Any plant with leaves, seeds, or flowers used for flavoring food and medicine.
Botanical
Substance obtained from a plant and used as an additive.
Amino Acid
A simple organic compound known as the building block of proteins.
Performance Supplements
Supplements intended to help enhance athletic performance.
Ergogenic Aids
Substances that enhance energy production and provide athletes with a competitive advantage.
FDA
A US federal department that regulates the production and distribution of food, pharmaceuticals, tobacco, and other consumer products.
Anemia
A condition marked by a deficiency of red blood cells or of hemoglobin in the blood resulting in extreme fatigue.
Dietary Reference Intakes
A set of standards estimating how much of a nutrient should be ingested that is used in planning eating patterns for healthy individuals.
Recommended Daily Allowance
The average daily level of intake that is sufficient to meet the needs of nearly all (97%-98%) healthy people.
Multivitamins
Supplements or pills containing a combination of vitamins and minerals.
Daily Value (DV)
Reference amounts expressed in grams, milligrams, or micrograms of nutrients to consume or not to exceed each day.
Fortified
Having had vitamins or other supplements added so as to increase the nutritional value.
Upper Limit (UL)
The highest level of nutrient intake that is likely to pose no risk of adverse effects for almost all individuals in the general population.
International Units (IU)
The quantity of a substance that has a biological effect. Amount varies depending on the substance.
Intrinsic Factor (IF)
A substance secreted by the stomach that enables the body to absorb vitamin B12.
Satiety
The feeling of fullness and satisfaction.
Energy Balance
The state achieved when energy intake is equal to energy expenditure.
Creatine Monohydrate
An organic compound that increases phosphocreatine levels and adenosine triphosphate (ATP) energy production leading to enhanced strength and power.
Antioxidant effect on exercise and performance
Minimizes free radical damage to skeletal muscle
Reduces muscle fatigue, inflammation, and soreness
Arginine effect on exercise and performance
Increases blood flow and delivery of oxygen and nutrients to muscle
Increases secretion of human growth hormone
Beta-alanine effect on exercise and performance
Increases synthesis of carnosine, a dipeptide that buffers changes in muscle pH, reducing muscle fatigue
Nitrate effect on exercise and performance
Dilates blood vessels in exercising muscle
Improves energy production
Branched-Chain Amino Acids effect on exercise and performance
Metabolized by mitochondria in skeletal muscle to produce energy during exercise
Branched-Chain Amino Acids
A group of three essential amino acids (leucine, isoleucine, and valine) that help the body build muscle and decrease muscle fatigue.
Caffeine effect on exercise and performance
Reduces perceived pain and exertion and increases fat metabolism
Calcium effect on exercise and performance
Improves bone and joint health and helps muscles contract
Citrulline effect on exercise and performance
Increases delivery of oxygen and nutrients to muscle
Creatine effect on exercise and performance
Helps muscles generate energy for short-term anaerobic activity
Glutamine effect on exercise and performance
Metabolism and energy production
Improves immune function and preserves protein stores
Reduces fatigue and decreases muscle soreness
Iron effect on exercise and performance
Increases oxygen uptake
Reduces heart rate and decreases lactate concentration during exercise, which in turn increases blood flow
Catabolic
Metabolic activity involving the breakdown of molecules such as proteins or lipids.
Anabolism
The building of complex molecules in the body from more simple, smaller molecules.
Muscle Protein Synthesis
A process that produces protein to repair muscle damage and oppose muscle breakdown.
Biological Value
The percentage of protein used by the body.
Bioavailability
The amount of a substance that enters the circulation when introduced into the body and is effective.
Protein Digestibility-Corrected Amino Acid Score
Measures the nutritional quality of protein.
Digestible Indispensable Amino Acid Score
Measures the amount of amino acids absorbed by the body.
Incomplete Proteins
A food source that lacks one or more of the nine essential amino acids.
Complete Protein
A food source containing all nine essential amino acids the body needs.
Anticatabolic
Properties that protect muscle mass from being broken down.
Refractory Period
A window where muscle protein synthesis (MPS) becomes resistant and amino acids are used for other processes.
Cell Proliferation
The process by which a cell grows and divides to produce new cells.
Polyunsaturated Fats
Fat molecules containing more than one unsaturated carbon bond, are liquid at room temperature, and solid when chilled.
Anabolicandrogenic Steroids
Synthetic variations of the male sex hormone testosterone.
Beta-Alanine
A nonessential amino acid that is naturally produced by the body.
Acidosis
When the kidneys and lungs cannot keep the body’s pH in balance due to excess acid in body fluids.
BCAAs
Leucine, Isoleucine, and Valine
Stimulants
A class of drugs that temporarily improve physical or mental function.
Cannabidiol (CBD) usage
