Domain I: Interviews and assessments Flashcards
Fast twitch muscle fiber
Muscle fibers that contract rapidly with low oxidative capacities. Also called type II fibers.
Fascia
The fibrous connective tissue that covers muscle while providing structural support.
Isometric
A muscular contraction in which the joint angle and muscle length doesn’t change.
Hyperextension
An extension of a part of the body beyond the normal range of motion.
Plantarflexion
A movement that flexes the toes toward the sole of the foot from the ankle.
V02 Max
The maximal oxygen uptake the body can use during a specified timeframe. Measures cardiovascular endurance through 1 minute per kilogram of bodyweight. Also referred to as maximum aerobic capacity.
Transverse Plane
An imaginary horizontal line that divides the body between upper and lower sections. Also referred to as the horizontal plane.
Adduction
Movement of a limb toward the midline or middle axis of your body.
Abduction
Movement of a limb away from the midline or middle axis of the body such as extending your arms outward.
Anaerobic Threshold
When the level of exercise intensity places demands on the body causing lactic acid to build up faster than it can be cleared away.
Basal Metabolic Rate
The amount of energy needed to maintain the basic functions of living.
Antagonist
When a muscle action counteracts the contraction produced by another muscle.
Base of Support
The area beneath your feet that includes all points of contact.
Axis of Rotation
The center line around which a joint or other body part moves in rotation.
Bone Mineral Density
Measures the mineral density in your bone. Indicates bone strength through calcium content.
Co-contraction
The simultaneous activation of antagonist muscles.
Distal
The furthest distance from the origin of a muscle; away from the center of the body.
Contusion
Injured tissues or skin where blood capillaries may have broken but the skin is not. Similar to a bruise.
Contraindication
Any physical condition that makes a movement or exercise inadvisable or inappropriate.
Delayed Onset Muscle Soreness
Describes muscle pain and soreness that typically occurs within 24 to 48 hours following strenuous exercise. It can result in restricted range of motion, tenderness and muscle weakness for a short period.
External Rotation
A movement of the body away from the midline; turning outward.
Dyspnea
Having difficulty in breathing; shortness of breath or labored breathing.
Elasticity
One of the functional characteristics of muscles that explains when a muscle is stretched, it returns to its original resting length.
Dorsiflexion
A movement that flexes the foot in an upward direction from the ankle.
