| EXCESS POST-OXYGEN CONSUMPTION (EPOC) |
|
Definition
| Known as oxygen debt, refers to oxygen uptake remaining elevated above resting levels for several minutes durning exercise recovery. |
|
|
Term
|
Definition
| A period in which the level of oxygen consumption is below what is necessary to supply appropriate ATP production required of any exercise. |
|
|
Term
|
Definition
| The point at which the body can no longer meet its demand for oxygen and anaerobic metabolism is accelerated. |
|
|
Term
|
Definition
| The ability of the body to remove oxygen from the air and transfer it through the lungs and blood to the working muscles; related to cardiorespiratory endurance. |
|
|
Term

Definition
| The volume of blood ejected by each ventricle of the heart durning a single sysole. |
|
|
Term
|
Definition
| The volume of blood pumped by each ventricle in one minute. |
|
|
Term
|
Definition
| The pumping action of the muscles in the extremities & respiratory system along with venconstriction to move oxygen-poor blood back to the heart. |
|
|
Term
|
Definition
| A condition caused by ceasing vigorous exercise too abruptly so that blood remains in the extremities and may not be delivered quickly enough to the heart and brain. |
|
|
Term
|
Definition
| The greatest volume of air that can be forcibly exhaled after the deepest inspiration. |
|
|
Term
|
Definition
| A dangerous condition that can occur if an individual holds thier breath, causing the glottis to close and stomach muscles to contract, forming an unequal pressure in the chest cavity, reduced blood flow to the heart, and insufficient oxygen supply to the brain. Dizziness, temporary loss of consciousness may occur. |

| WHAT IS THE BLOOD PRESSURE NORMS |
|
Definition
Rest blood pressure of the healthy person averages around 120/80 mmHg
A resting blood pressure of 140/90 is concidered to be high. |

Term
|
Definition
| Bending of a joint between two bones that decreases the angle between the two bones. |
|
|
Term
|
Definition
| A motion of increasing the angle between two bones, straightening of a muscle previously bent in flexion. |

| Are the muscles performing the work. |
|
|
Term
|
Definition
| Are the muscles that help perform the same task. |
|
|
Term
|
Definition
| Help prevent undesired or unnecessary motions. |
|
|
Term
|
Definition
| No joint movement occurs, however energy is expended & calories are burned to maintain the contraction. Muscle will only be strong at the joint angle used. |
|
|
Term
|
Definition
| The muscle fibers are shortening & positive work is done against gravity or an external resistance. Requires the most energy. |
|
|
Term
|
Definition
| Or negative work, occurs when the muscle fibers lengthen & the bony levers move into the direction of gravity. Requires the least amount of energy. |
|
|
Term
|
Definition
| Is one in which the tension remains constant as the muscle shortens or lengthens (Free weights/resistance machines) |
|
|
Term
|
Definition
| Controlled or movements are those in which the muscle shortens at a constant rate, and cannot be done without the use of specialized equipment. |

| What fibers are designed for prolonged, submaximal aerobic activities & are slow to fatigue, they are used for long term, low to moderate intensity activites ranging from maintaining proper posture to long distance running. |
|
|
Term
|
Definition
| What fibers are ablt to generate quick, high intensity contractions but are more easily fatigued because they rely predominately on anaerobic metabolic system for energy. |

Definition
| (Bent backward) Is increased concave curve in the lumbar portion of the spine. |
|
|
Term
|
Definition
| A reaction in which two receptors, the muscle spindle and the golgi tendon organ (GTO) detect when a muscle has been extended or stretched & respond by cuing the muscle to contract or release. Anytime a muscle stretched, a signal is sent to contract that same muscle. |
|
|
Term
|
Definition
| Could strain the muscle. It includes bouncing or explosive movement unsustained. Causes muscle soreness. The muscle spindles sense the changes in muscle length & causes a muscular contraction. |
