Equations

100

Equation for cardiac output

CO = HR x SV

200

Equation for Mean arterial pressure

MAP = diastolic + 1/3 pulse pressure

Pulse pressure = systolic - diastolic

300

What is the Fick equation (for V_O2 max)

V_O2= Q x a-V_O2

Q = cardiac output

a-V_O2 = arterio-venous difference

400

What is the Rate pressure product 

RPP = HR x SBP

- calculated during exertion

500

What is the pulmonary ventilation equation

V_E = RR x V_T

RR = respiratory rate

V_T = tidal volume

Terminology

100

This type of muscle is adaptive for strength and power activities

Type IIB Fast-twitch Glycolytic

200

This is the % of blood pumped from ventricle/beat

Ejection fraction (EDV-ESV)

300

This term relates to conductivity (+ or -)

Dromotropic

400

This type of muscle is for endurance type activities

Type I Slow-twitch oxidative

500

This is the force/resistance the muscular wall of a ventricle has to exert/overcome to contract [systolic load]

Afterload

More terminology

100

This refers to the response when the right atrium dilates and right atrial pressure increases

- HR inc. 10-15 bpm if heart is @ normal rate

- inc. heart contractility

Bainbridge's Reflex (volume reflex)

200

This is the oxygen utilized by the muscles/tissues, the "peripheral" component that is important for improving functional capacity in severely compromised left ventricular function

a-V_O2 (Arterio-Venous Difference)

300

This is a major determinant of CO during moderate-maximal exercise

HR

400

This refers to increased ventricular stretch that will lead to increased force of contraction

Frank-Starling principle

500

This is the amount of tension on the ventricular wall before it contracts [EDV]

Preload

Some mo' terminology

100

What is an augmentation of the energy utilization of the muscle by means of an exercise program?

Conditioning (a process)

200

This term relates to contractility (+ or -)

Inotropic

300

Doubly Labelled Water (DLW), calorimetry and CPET are three methods for this measurement

Energy expenditure (EE)

400

This term relates to rate/timing (+ or -)

Chronotropic

500

What is the normal % for Ejection fraction?

55-70%

Etc.

100

What classifies as a severe dysfunction % of ejection fraction?

30-35%

200

T/F: number of capillaries surrounding each skeletal fiber decrease w/ adaptations to exercise training

False

300

What classifies as a critical dysfunction % for ejection fraction? 

<30 %

400

T/F: Hemoglobin initially decreases then increases

True

500

T/F: It's common/normal for SBP to plateau w/ prolonged (30-45 minutes) exercise at the same workload

True
