Anaerobic Glycolysis
the bioenergetics system that supplies ATP during short term, high-intensity exercise through the breakdown of glycogen
Anaerobic Threshold
the point during progressively intense exercise at which the muscles lose the ability to utilize oxygen to create energy (i.e. ATP) and blood lactate levels begin the sharply rise
Anatomical Position
standing in an tall position, feet hip-width apart with the toes pointing forward, the arms hanging to the sides of the body, palms of the hands facing forward, and the head and eyes looking straight ahead
Angular Momentum
the reluctance of a bodey segment or object to stop rotating around an axis of rotation as determined by the product of the object’s mass, the distance from the axis of rotation, and the velocity of the object
Anorexia Nervosa
an eating disorder characterized by self-starvation, failure to maintain a minimally normal weight, an irrational fear of gaining weight or becoming fat, and a preoccupation with body shape
Antagonist
the muscle or group of muscles which oppose the agonist muscles
Anterior
a point or body part located in the front of the body

rotational movement of the pelvis such that the anterior superior iliac spine of the pelvis moves forward relative to the pubic bone
Appendicular Skeleton
the 126 bones that include the upper and lower extremities as well as the shoulder and pelvic girdles
Appreciative Inquiry
an approach to coaching behavioral change that focuses on exploring and amplifying an individual’s strengths and that which is good
Arterial-Venous Oxygen Difference
the amount of oxygen removed from the arterial blood and taken into the mitochondria within the skeletal muscle. Also called oxygen extraction
Asthma
a chronic inflammatory disease that affects the lining of the airways within the lungs
Autogenic Inhibition
decreased muscle tension or relaxation of a muscle that is facilitated by stimulation of the golgi tendon organs
Automated External Defibrillator
a small portable electronic device used to analyze the heart’s rhythm and provide defibrillation of irregular heartbeats through the delivery of a small electrical shock
Axial Skeleton
the 80 bones that include the skull, spinal column, sternum and ribs
Balance
the ability to control the position of the body against external forces

Base of Support
the points of contact between the body and the ground or another surface or object

regular pulsation that creates an even rhythm within music. Also referred to as a count
Beats Per Minute
the number of beats of the heart per minute. Also refers to the number of beats that occur within one minute of music
Binge-Eating Disorder
an eating disorder characterized by recurrent episodes of eating significantly more food in a short period of time than most people would eat under similar circumstances, with episodes marked by feelings of lack of control
Blood Pressure
the pressure exerted by the circulating blood against the walls of the blood vessels, equal to the product of the cardiac output and the total peripheral vascular resistance
Body Composition
the relative amount of fat mass and lean body mass throughout the body, expressed as a percentage of body fat
