Front 9

Maximal Oxygen Uptake

Back 9

The Greatest Amount of Oxygen that:
- Can be used at the Cellular Level for the Entire Body

- Correlation is accepted as Measurement of Cardiorespiratory Fitness

Front 10

Diastolic Blood Pressure

Back 10

Used to estimate the:
- Pressure exerted against the arterial walls when
- No Blood is being forcefully ejected through the walls
- AKA Diastole

Front 11

Systolic Blood Pressure

Back 11

Estimates the Pressure Exerted against the:
- Arterial Walls as Blood is Forcefully Ejected during the Ventricular Contraction
- aka Systole

Front 12

Mean Arterial Pressure (Definition/Equation)

Back 12

The average blood pressure throughout the Cardiac Cycle

Mean Art. BP = (SBP-DBP/3) + DBP

Front 13

Total Peripheral Resistance

Back 13

The resistance of the Entire Systematic Circulation

ion = Increased Resistance

vasodilation = Decreased resistance

Front 14

Adaptation to Acute Aerobic Exercises

Back 14

Increased:
- Cardiac Output
- Stroke Volume
- HR
- Vo2
- SBP
- Blood Flow to active muscles
- Decrease in DBP

Front 15

Minute Ventilation

Back 15

The Volume of Air Breathed in a Minute

Front 16

Tidal Volume

Back 16

The Amount of Air Inhaled and Exhaled with each breath

Front 17

Ventilatory Equivalent

Back 17

The ratio of:
- Minute Ventilation to
- Oxygen Uptake

Ranges between:
20-25L of Air/liters of O2 consumed

Front 18

Physiological Dead Space

Back 18

The Alveoli in which Poor:
- Blood Flow
- Ventilation
- Other problems with Alveolar Surface

Impair Gas Exchange

Front 19

Aerobic Gas Exchange Process

Back 19

Large Amounts of O2 Diffuse from:
- Capillaries to Tissues

Increased levels of CO2 move from:
- Blood to Alveoli

Minute Ventilation Increases to Maintain Appropriate Alveolar Concentrations of these Gases

Front 20

Diffusion

Back 20

The Movement of O2 and CO2 Across
- Cell Membrane

Is a function of the Concentration of Each Gas

Molecular motion is determined by Partial Pressure

Front 21

Aerobic Training Adaptions

Back 21

Increased:
- Max Cardiac Output
- Increased Stroke Volume

Reduced:
- Heart Rate at Rest/submax exercise

Front 22

Vasoconstriction

Back 22

Narrowing of Blood Vessels as a result of:
- Contraction of the Muscular wall of the vessel

Front 23

Vasodilation

Back 23

Widening of Blood Vessels as a Result of:
- Relaxation of the Muscular wall of the Vessel

Front 24

Venous Return

Back 24

The amount of Blood Returning to the Heart

Front 25

Ventilatory Equivalent

Back 25

The Ration of:
- Minute Ventilation to
- Oxygen Uptake

Front 26

Alveoli

Back 26

The functional unit of the Pulmonary System

Where gas exchange occurs

Front 27
