Discussion
1- Define the key terms. For those terms which are measurable variables, describe in your ownwords what they mean (not how they are obtained or calculated). Indicate the unit(s) ofmeasurement.
a. Diastolic Blood Pressure (DBP):
b. Mean Arterial Pressure (MAP):
c. Rate Pressure Product (RPP):
d. Systolic Blood Pressure (SBP):

2- on the basis of your analyses, compare and contrast the patterns of cardiovascular responses
(HR, SBP, and DPB) between the different types of exercise:
a) between incremental aerobic exercise based on Lab 3 *: Maximal Oxygen Consumption (ifthe subject from this lab did not do the VO2max test, comment on what responses wouldhave been seen in an incremental aerobic exercise test to maximum) versus incrementalresistance exercise measured in this lab
*(from Lab 3 VO2maxwas:
? Relative maximal (VO2) = 21.21 mL/kg/min
? Absolute maximal (VO2) = (21.21 x 95)/1000 = 2.01 L/min
? Maximal HR = 192 bpm )

and

b) between steady state submaximal aerobic exercise and constant load dynamic resistanceexercise.

3- Explain what RPP means (indicates) physiologically.

4- Why does DBP react differently to a continuous rhythmical activity (i.e. cycle ergometry)compared to a static or dynamic resistance activity? Be sure to include how DBP reacts toeach of these exercise conditions.
5- Explain the patterns of response for each of the major cardiovascular variables (cardiac output,stroke volume, heart rate, SBP, DBP, MAP, and RPP) during dynamic resistance exercise. Besure to explain the physiological mechanisms for each response.

6- Among the instructions given for taking blood pressure during the bicycle ergometer ride wasthe caution not to grip the handlebars when the blood pressure measurement was being taken.What is the physiological reason for this caution and how would you expect the values yougraphed to change if the subject were gripping the handlebars tightly?
