This measures pressure in your arteries when your heart beats (heart is contacting). The bottom number is the diastolic pressure. The diastolic blood pressure measure the pressure in the arteries between heartbeats (heart muscle is resting). A health blood pressure is when the systolic number is not greater than 120 and the diastolic number is less than 80. 2.
The range of resting SVR for the subjects in this experiment is 10.2–12.03 mmHg per min/L. Did SVR increase, decrease, or not change with exercise? The SVR decreased with exercise. DISCUSSION 1. Explain what caused the observed changes in systolic BP and MAP with the exercise.
Read the following information and study the examples provided before completing this activity. Obtain your Maximum Heart Rate (MHR) by subtracting your age from 220. Example 220 – 21 = 199 Your Information 220 - _16___ = __204__ (your MHR) Subtract your resting heart rate (RHR) that you calculated in Part II above from the maximum heart rate (MHR) that you just determined in Step 1. Example 199 - 70 (RHR) = 129 Your Information (MHR – RHR = ____) __204__ - _68___ = _136____ Determine the percent of heart rate reserve at which you choose to train. The lower limit of heart rate reserve for training purposes is 50% of your answer from Step 2.
Did the tidal volume increase, decrease, or not change with exercise? increace with exercise 3. Did the expiratory reserve volume increase, decrease, or not change with exercise? decreased with exercise 4. Did the inspiratory reserve volume increase, decrease, or not change with exercise?
