What was the purpose of the cardiovascular responses to exercise lab?

To determine cardiovascular responses to aerobic exercise at different exercise intensities.

Which to arteries were marked?

The radial and brachial arteries

What is the formula for pulse pressure and what does it indicate?

PP = SBP - DBP




Pulse pressure is an indication of the stroke volume of each heart beat.

What is the formula for mean arterial pressure and what does it indicate?

At rest: MAP = 1/3(SBP - DBP) + DBP


During exercise: MAP = 1/2(SBP - DBP) + DBP




MAP is an indication of the average pressure exerted against arterial walls during the cardiac cycle.

What is the formula for the rate pressure product and what does it indicate?

RPP = (HR * SBP) / 100




RPP is an indication of myocardial VO2

How does exercise impact blood pressure?

Raises systolic blood pressure while diastolic blood pressure remains relatively the same.

How does exercise impact stroke volume?

There is a rise in stroke volume until the subject reaches about 40% VO2 max. After reaching 40% VO2 max, stroke volume reaches a steady state.

How does exercise impact cardiac output?

There is an increase in cardiac output.

How does exercise impact heart rate?

There is a steady increase in heart rate.

Describe the procedure for the cardiovascular responses to exercise lab.

Start at 1.0 kp at 60 rpm; Increase kp by 1.0 for each three minute stage. During the last min of each stage, measure HR and BP. Subject was taken to exhaustion (can no longer cycle at 60 rpm).

How was the subject's heart rate taken during the lab?

Lab partner counted the HR via the radial artery for 10 secs and then multiplied that number by 6.

When taking an individual's blood pressure, how does one identify systolic blood pressure?

The first point at which a steady, continuous heart beat can be heard.

When taking an individual's blood pressure, how does one identify diastolic blood pressure?

The first point at which a steady, continuous heart beat can no longer be heard.

What does "plethys" mean?

old green word for pressure

What does the Archimedes' principle state?

"An object immersed in water is buoyed up by a force equal to the weight of the water displaced."

What is Boyle's Law?

P1V1 = P2V2




States that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.

What is Charles' Law?

V1T2 = V2T1




States that the temperature and the volume will directly related to each other when the pressure is held constant. Gases tend to expand when heated.

How does one calculate the volume of an individual using the Bod Pod?

The volume of air inside of an empty bod pod is calculated. Then, the volume of air inside of the bod pod with the subject inside is calculated. Volume_empty - Volume_subject = Subject body volume.

How does an increase in volume impact density?

Density is decreased.

How does an increase in temperature impact density?

An increase in temperature would increase the volume. Therefore, the density would decrease.

What factor influences the accuracy of BIA the most?

The individual's level of hydration.
