1

Atrium

An upper chamber of the heart that functions to pump blood to the lower chamber of the heart (i.e., ventricle). (NSCA CPT, pg. 37)

2

Ventricle

A lower chamber of the heart that functions to pump blood from the heart (right ventricle pumps to the lungs, left ventricle pumps to the body).
(NSCA CPT, pg. 37)

3

Total Peripheral Resistance

The impedance of blood flow caused by exercise, nervous stimulation, metabolism, and environmental stress. (NSCA CPT, pg. 39)

4

Systolic Blood Pressure (SBP)

The pressure exerted against the arterial walls as blood is forcefully ejected during ventricular contraction (systole). (NSCA CPT, pg. 40)

5

Diastolic Blood Pressure (DBP)

The pressure exerted against the arterial walls between beats when no blood is ejected from the heart or through the vessels (diastole). (NSCA CPT, pg. 40)

6

Rate-Pressure Product (RPP)

An estimation of the work of the heart (i.e., double product; HR 􏰀 SBP). (NSCA CPT, pg. 40)

7

Mean Arterial Pressure (MAP)

The average blood pressure throughout the cardiac cycle (i.e., [(SBP − DBP) ÷ 3] + DBP). (NSCA CPT, pg. 40)

8

Cardiac Output

The quantity of blood pumped by the heart per minute expressed in liters or milliliters (i.e., SV 􏰀 HR). (NSCA CPT, pg. 40)

9

Sympathetic Nervous System

A part of the nervous system that, when stimulated, speeds up various systems of the body (increases heart rate). (NSCA CPT, pg. 40)

10

Stroke Volume

The quantity of blood ejected by the left ventricle expressed in milliliters of blood per beat.(NSCA CPT, pg. 40)

11

End-Diastolic Volume

The volume of blood from the left atrium that is available to be pumped by the left ventricle. (NSCA CPT, pg. 40)

12

Venous Return

The return of the blood to the right atrium from the body (periphery). (NSCA CPT, pg. 41)

13

Maximal Oxygen Uptake (VO2 Max)

The highest capacity for oxygen consumption or utilization by the body during maximal physical exertion; also referred to as aerobic capacity, maximal aerobic power, maximal oxygen consumption, or V. O2 max and sometimes functional capacity. (NSCA CPT, pg. 45)

14

Electrocardiogram

A way to record the electrical activity of the heart at the surface of the body using electrodes on the chest. (NSCA CPT, pg. 38)

15

Cardiac Output equation

Q = SV X HR. (NSCA CPT, pg. 40)

16

Stroke Volume equation

SV = EDV - ESV. (NSCA CPT, pg. 40)

17

Cardiac Output other equation

Q = (EDV - ESV) X HR. (NSCA CPT, pg. 40)

18

Spirometry

A method used to examine the static lung volumes. (NSCA CPT, pg. 41)

19

Oxygen Uptake

The amount of oxygen used by the tissues of the body. (NSCA CPT, pg. 44)
