Front Back
Myocardial Infarction
Hear attack occurs due to lack of blood flow through the coronary arteries to the heart muscle
lack of blood flow
Stroke Volume
the amount of blood pumped with each beat or systole
Cardiac Output
heart rate x stroke volume. usually measured in liters (or milileters) of blood pumped per minute
Venous Return
The amount of blood returned to the heart by the veins
Valsalva Maneuver
occurs when a person holds his or her breath during a strenuous activity, such as lifting weights or shoveling snow
Minute Ventilation
total amount of air breathed per minute
Residual lung volume
amount of air remaining in the lungs after a complete and total forced exhale
Forced vital capacity
amount of air that can be forcefully exhaled after a maximal inahle
Total lung capacity
sum of the residual volume and the forced vital capacity
body\'s usable form of carbohydrate
Lactic Acid
produced in muscles during rapid exercise when the body cannot supply enough oxygen to the tissues
a metabolic process that breaks down carbohydrates and sugars through a series of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of ATP
a subcellular structure where oxidation takes place
Beta oxidation
A metabolic sequence that breaks fatty acids down to two
Krebs cycle
the acetyl CoA formed in the first component of aerobic metabolism enters into the citric acid cycle
Electron transport system
the final sequence of reactions in the aerobic production of ATP
Maximal oxygen uptake
the maximum amount of oxygen consumed and utilized by the body during an all
Excess Post
Exercise Oxygen Consumption
each section of a myofibril in muscle
structural protein that makes up the thin filaments of myofibrils; functions in muscle contraction
Anatomical Position
standing position with hands down and palms facing forward
lying on the spine
lying face down
Axial Skeleton
part of the skeleton that contains skull, vertebral column, ribs, and sternum
Synovial joints
have a small space between the articulating bones that allows for a greater range of motion
a white, semi
Synovial membrane
secretes synovial fluid which provides nourishment, lubrication, and hydrotastic cushioning for the joint
band of fibrous tissue that connects bone to bone and provides joint stability.
dense, fibrous connective tissue that forms the end of a muscle and attaches muscle to bone
fibrous connective tissue that forms sheaths for individual muscles.
Circuit Weight Training
resistance exercises performed one after the other without rest for approximately 20 minutes
Muscular Strength
maximum force a muscle or muscle group can generate at one time
Muscle Endurance
capacity to sustain repeated muscle actions, as in push
Muscle Power
explosive aspect of strength, is the product of strength and speed of movement
Muscle Stability
ability of a muscle or muscle group to stabilize a joint and maintain its position without movement. (to perform a sustained isometric contraction)
Muscle hypertrophy
an increase in the muscle fiber size, specifically an increased cross
Overload Principle
increasing the intensity (resistance), frequency, or duration of the training above the levels normally expected
specific adaptions in the metabolic and neuromuscular systems depending on the type of program or exercises that are performed
total number of repetitions performed multiplied by the total amount of weight, or resistance, used during a single training session. (Reps x Weight = Volume)
Progressive resistance exercise
resistance must be gradually, progressively increased as the muscles adapt to a given exercise
variations in the training program over the course of several months or a year, that help to improve performance and prevent injury, staleness, and burnout
a point where further increases in strength become difficult and progress seems to stop
Set System
Set system
Set System
Set System
Dynamic Constant Resistance
external resistance or weight that does not vary through the range of motion
Dynamic Variable Resistance
attempts to match the external resistance to the exerciser\'s strength curve. Strength varies throughout the range of motion of each muscle
