Active recovery
Continuing to move immediately after an exercise segment is completed but at a lower intensity.
Activities of daily living (ADL)
Activities normally performed for hygiene, bathing, household chores, walking, shopping. and similar activities.
Acute
Descriptive of a condition that usually has a rapid onset and a relatively short and severe course; opposite of chronic.
Acute myocardial infarction (AMI)
A myocardial infarction resulting from acute obstruction of a coronary artery. See also Myocardial infarction.
Adduction
Movement toward the mid line of the body.
Adenosine triphosphate (ATP)
A highenergy phosphate molecule required to provide energy for cellular function. Produced both aerobically and anaerobically and stored in the body.
Adequate Intake (Al)
A recommended nutrient intake level that, based on research, appears to be sufficient for good health.
Adherence
The extent to which people follow their plans or treatment recommendations. Exercise adherence is the extent to which people follow an exercise program.
Adhesion
A fibrous bond of scar tissue forming between two surfaces.
Adipocyte
A fat cell.
Adiponectin
A hormone related to energy metabolism regulation that facilitates the action of insulin by sending blood glucose into the body’s cells for storage or use as fuel, thus increasing the cells’ insulin sensitivity or glucose metabolism.
Adipose
Fat cells stored in fatty tissues in the body.
Adulterated
A supplement is considered adulterated if it, or one of its ingredients, presents a “significant or unreasonable risk of illness or injury” when used as directed, or under normal circumstances.
Aerobic
In the presence of oxygen.
Affiliate
A facility or business that is connected or attached to a larger organization or company.
Affirmation
A positive statement to accentuate a client’s strengths or effort.
Agility
The ability to move quickly and easily; a skill-related component of physical fitness.
Agonist
The muscle directly responsible for observed movement; also called the pnme mover.
Agreement to participate
Signed document that indicates that the client is aware of inherent risks and potential injuries that can occur from participation.
Air displacement plethysmography (ADP)
A body-composition assessment technique based on the same body volume measurement principle as hydrostatic weighing; uses air instead of water.
Allergen
A substance that can cause an allergic reaction by stimulating type-1 hypersensitivity in genetically susceptible individuals.
Altitude sickness
An altitude-induced illness caused by exercising at a moderate to high altitude without acclimatizing to the decreased partial pressure of oxygen in the air, resulting in less oxygen being carried in the blood. Symptoms include shortness of breath, headache, lightheadedness, and nausea.
Alveoli
Spherical extensions of the respiratory bronchioles and the primary sites of gas exchange between the lungs and the blood.
Ambient temperature
The temperature of the surrounding air; room temperature.
Ambivalence
A state of having mixed feelings about a change; arguing both for and against change simultaneously.
American Society of Composers, Authors, and Publishers (ASCAP)
One of two performing rights societies in the United States that represent music publishers in negotiating and collecting fees for the nondramatic performance of music.
Amino acid
Nitrogen-containing compound that is one of the building blocks of protein.
Amortization phase
The transition period between the eccentric and concentric actions during plyometrics; a crucial part of the stretch-shortening cycle that contributes to power development.
Anabolic
Muscle-building effects.
Anaerobic
Without the presence of oxygen.
Anaerobic efficiency
The ability to use the energy systems that do not require the presence of oxygen to contribute to the total energy needs during physical activity.
Anaerobic glycolysis
The metabolic pathway that uses glucose for energy production without requiring oxygen. Sometimes referred to as the lactic acid system or anaerobic glucose system, it produces lactic acid as a by-product.
Anatomical position
Standing erect with the arms hanging by the side and the head, eyes, feet, and palms facing forward.
Android
Adipose tissue or body fat distributed in the abdominal area (appleshaped individuals).
Anemia
A reduction in the number of red blood cells and/or quantity of hemoglobin per volume of blood below normal values.
Anemic
See Anemia.
Aneurysm
A localized abnormal dilation of a blood vessel; associated with a stroke when the aneurysm bursts.
Angina
A common symptom of coronary artery disease characterized by chest pain, tightness, or radiating pain resulting from a lack of blood flow to the heart muscle.
Angioplasty
A surgical procedure that involves inserting a catheter into a blocked coronary artery. A narrow balloon is then inflated inside the artery, to widen the artery. Also called percutaneous transluminal coronary angioplasty (PTCA).
Angiotensin II receptor antagonist
A class of drugs used to treat high blood pressure and other conditions by preventing angiotensin II from binding to angiotensin II receptors, thereby allowing blood vessels to dilate; also referred to as angiotensinreceptor blockers.
