Study Guide Flashcards
Obesity
The condition of being considerably overweight, and refers to a person with a body mass index of 30 or greater, or someone who is at least 30 pounds over the recommended weight for their height.
The condition of subcutaneous fat exceeding the amount of lean body mass.
Overweight
Refers to a person with a bodymass index of 25 to 29, or, who is between 25 to 30 pounds over the recommended with for their height.
Proprioception
The cumulative sensory input to the central nervous system from all mechanoreceptors that sense body position and limb movements
Super Set
Set of two exercises that are performed back-to-back, without any rest time between them.
Human Movement System
Nervous System, Muscular System, Skeletal System
Neuron
The functional unit of the nervous system.
Mechanoreceptor
Sensory receptors responsible for sensing distortion in body tissues.
Muscle Spindles
Receptors sensitive to change in length of the muscle and the rate of that change.
Golgi Organ Tendon
Receptors sensitive to change in tension of the muscle and the rate of that change.
Joint Receptor
Receptors surrounding a joint that respond to pressure, acceleration, and deceleration of the joint.
Arthrokinematics
- Joint motion.
2. The motions of joints in the body.
Slow Twitch (Type 1 muscle Fibers)
Another term for type 1 muscle fibers, fibers that are characterized by a greater amount of capillaries, mitochondria, and myoglobin. These fibers are usually found to have a higher endurance capacity than fast twitch fibers.
Fast Twitch (Type 2 muscle Fibers)
Muscle Fibers that can also be characterized by the term type IIA and IIB. These fibers contain fewer capillaries, mitochondria, and myoglobin. These fibers fatigue faster than type I Fibers.
Atrium
The superior chamber of the heart that receives blood from the veins and forces it into the ventricles.
Ventricle
The Inferior chamber of the heart that receives blood from its corresponding atrium and, in turn, forces blood into the arteries.
Sinoatrial SA Node
A specialized area of cardiac tissue, located in the right atrium of the heart, which initiates the electrical impulses that determine the heart rate; often termed the pacemaker of the heart.
Cardiac Output
Heart rate x Stroke Volume, the overall performance of the heart.
Gluconeogenesis
The formation of glucose from noncarbohydrate sources, such as amino acids.
Adenosine Triphosphate
Energy storage and transfer unit within the cells of the body.
ATP-PC System
Energy storage and transfer unit within the cells of the body.
Glucose
A simple sugar manufactured by the body from carbs, fats, and to a lesser extent proteins, which serves as the bodies main source of fuel.
Excess Post Oxygen Consumption
The state in which the body’s metabolism is elevated after exercise.
Sagittal Plane
An imaginary bisector that divides the body into left and right halves.
Frontal Plane
An imaginary bisector that divides the body into front and back halves.
Transverse Plane
An imaginary bisector that divides the body into top and bottom halves.
Posterior
On the back of the body.
Anterior
On the front of the body.
Lateral
Positioned toward the outside of the body.
Medial
Positioned towards the middle of the body.
Superior
Positioned above a point of reference.
Inferior
Positioned below a point of reference.
Flexion
A bending movement in which the relative angle between two adjacent segments decreases.
Extension
A straightening movement in which the relative angle between two adjacent segments increases.
Abduction
A movement in the frontal plane away from the mid-line of the body.
Adduction
A movement in the frontal plane back toward the midline of the body.
Concentric
When a muscle is exerting force greater that the resistive force, resulting in shortening of the muscle.
Eccentric
An eccentric muscle action occurs when a muscle develops tension while lengthening.
Isometric
When a muscle is exerting force equal to the force being placed on it leading to no visible change in the muscle length.
Isokinetic
When a muscle shortens at a constant speed over the full range of motion.
Length-tension relationship
The resting length of a muscle and the tension the muscle can produce at this resting length.
Force Couple
Muscle groups moving together to produce movement around a joint.
Motor Learning
The integration of motor control processes with practice and experience that lead to relatively permanent changes in the capacity to produced skilled movements.
Motor Behavior
The manner in which the nervous, skeletal, and muscular systems interact to produce an observable mechanical response to the incoming sensory information from the internal and external environments.
Motor Control
The involved structures and mechanisms that the nervous system uses to gather sensory information and integrate it with previous experiences to produce a motor response.
