Homework Assignment
Chapter 08: Cardiorespiratory Responses to Acute Exercise
1. List 6 components of the cardiorespiratory system that occur during acute exercise.
1) Heart Rate
2) Stroke Volume
3) Cardiac output
4) Blood Pressure
5) Blood Flow
6) The Blood
2. As heart rate INCREASES or decreases, the intensity of exercise INCREASES or decreases.
3. Define maximum heart rate (HRmax). The Highest HR value achieved in an all-out effort to the point of volitional fatigue.
4. Why is the 208-(0.7 x age) equation recommended to predict HRmax, instead of 220-Age equation?
The 220-age equation formula calculates the HRmax was the too broad with highest HRmax that isn’t achieved …show more content…
Stroke volume – increase, maintain or DECREASE
b. Heart rate – INCREASE, maintain or decrease
c. Cardiac Output - increase, MAINTAIN or decrease
d. Arterial blood pressure - increase, maintain or DECREASE
18. Why would those alterations above be a problem? We are trying to avoid dehydration and increased body temperature.
19. What are three changes that occur in the blood during exercise? (HINT: Brown box on p. 196)
1) The (a-v)02 difference increase.
2) Plasma volume decreases
3) Hemoconcentration occurs as plasma volume decrease
20. How does pulmonary ventilation respond to increasing intensities of exercise? (pg. 196-197; Fig. 8.13)
a) At light intensities: accomplished by increase in tidal volume
b) At moderate intensities: increase ventilation rate to steady state value at light and moderate.
c) At higher intensities: rate of respiration increase
21. Define the terms:
a. Dyspnea – shortness of breath (labored or difficulty breathing)
b. Hyperventilation – breathing rate or tidal volume greater than necessary for normal function.
c. Valsalva maneuver – holding breath and try to compress contents of abs and thoracic cavities.
d. Ventilatory threshold – ventilation increase disportionately to increase in oxygen
