HERS 380 Laboratory Methods
in Exercise Science
Exercise Blood Pressure
Measure blood pressure for one person at
rest, during exercise, and recovery as described in the laboratory manual on page 185, Table 17.2. Another member
of the group should measure the subject's heart rate (via heart
rate monitor or palpated at the wrist) as the blood pressure
readings are taken. This should be done while the subject is
exercising on the cycle ergometer or on the treadmill. You will
need one data sheet. Your lab assignment should be written using only
data from the cycle ergometer data.
In order to answer the discussion questions you
will need the following information for each subject: age,
gender, exercise intensity for each measurement, SBP and DBP for
each measurement, heart rate for each measurement, and if
possible, fourth-phase pressures.
Determine the following:
- Heart rate values for all measured time points
- Rate-pressure product
and mean arterial pressure for each time point (rest, exercise and
recovery), and present these in table format.
- Present SBP and DBP data for one
subject in a graph illustrating the effect of exercise intensity
(Do not graph recovery values) on blood pressure. Sample Graph. Place those not included in the graph (recovery values) in a table.
Discussion items:
- Did systolic blood pressure change as
expected during exercise? Explain. Do not simply answer yes or
no, but discuss this. As with other discussion questions of this
nature on lab reports your expectations should be based on what
you know about your subject before taking these measurements -
age, gender, weight, height, training status, and health status. How did your subject's responses compare to values provided in Table 17.1 of your text?
Look at the changes seen with each power increase during
exercise. Explain.
- Did systolic blood pressure change as
expected during recovery? Explain. Do not simply answer yes or
no, but discuss this.
- Did diastolic blood pressure change as
expected during exercise? Explain. Do not simply answer yes or
no, but discuss this. How did your subject's responses compare to values provided in Table 17.1 of your text?
Look at the changes seen with each power increase during
exercise. Explain.
- Did diastolic blood pressure change as
expected during recovery? Explain. Do not simply answer yes or
no, but discuss this.
- Did your subject experience
blood pressures ( consider both SBP and DBP separately) that are considered warning signs
for termination of the test? What were the highest values for SBP & DBP for your subject? How do these compare to values that would prompt termination of a test? Was this expected for your subject? Explain why or why not.
