After obtaining 10–20 s of stable heart rate values, rise rapidly to a standing position. Continue to record data until the baseline heart rate has been achieved, or until the end of the run. Data will be collected for at least 200 s. Determine the baseline heart rate. Tap and drag over the area of the graph where the resting heart rate is displayed to select the data. Choose Statistics from the Analyze menu and record the mean heart rate, to the nearest whole number, in Table 2. Choose Statistics from the Analyze menu to turn off statistics. Determine the maximum heart rate over the entire run. Choose Statistics from the Analyze menu and record the maximum heart rate in Table 2. Choose Statistics from the Analyze menu to turn off statistics. Determine the baroreceptor response time for squatting. Tap the data point that represents the heart rate immediately prior to squatting and record the time component of this point. Tap the point that represents the maximum or minimum heart rate (first peak or valley) that follows squatting and record the time component of this point. Determine the difference between the two time values, and record this value in Table ∆x, 3 (to the nearest whole number) as time “Response 1.” Repeat Step 10 for the following regions: From the maximum or minimum heart rate following squatting to the beginning of a new stable heart rate. Record the value (time) in Table 3 as time ∆x “Recovery 1.” The region just prior to standing and the maximum heart rate after standing. Record the value (time) in Table 2 as time ∆x “Response 2.” The region between the maximum heart rate after standing and the point at which the heart rate has re-stabilized (i.e., stable for at least 40 s). Record the value (time) in ∆x Table 3 as time “Recovery 2.” Observations/Data: Table 1 - Exercise Resting Heart Rate (bpm) Maximum Heart Rate (bpm) Recovery Time (s) Table 2 Baroreceptor Stimuli – Baseline Heart Rate (bpm) Minimum Heart Rate (bpm) Maximum Heart Rate (bpm) Table 3 Baroreceptor Stimuli – Baroreceptor Baroreceptor response time 1: Recovery time 1 (s) response time 2: Recovery time 2 (s) Squatting (s) Standing (s)
