Study Questions
1. Compare the results of the Rockport Walking test and the 1.5-mile run test. What
are the similarities and differences between the tests?
They both give you results on fitness using distance traveled and HR as
Rockport test would not press an individual to go faster and work harder
so it may more suitable for seniors
1.5 mile test is more strenuous because intensity is higher
You will raise your HR higher for 1.5 mile run test
2. Choose an ergogenic aid that is reported to improve aerobic power. It could be
one of those mentioned in the Study Guide or a different one. Discuss the claims
made, and the accuracy of these claims.
1. hormone that is given to patients of kidney failure
2. Stimulates growth of more red blood cells (raises hemocrit levels)
which also makes blood more thick (can be dangerous)
3. On television, you occasionally see professional football players breathing pure
oxygen during their time-out periods. Would you recommend this practice?
No, it is minimally benefiecial
Hemoglobin in blood is already almost fully saturated with oxygen
Partial pressure of oxygen in the air would be increased so there may be
very minimal benefit
4. A 25-year-old man has been on an aerobic conditioning program for the past six
months. During that time, his maximum oxygen uptake and running performance
have been continuously improving. For the next few months, he will be quite busy
and he won’t have as much time to train, but he wants to maintain his current
aerobic fitness level. What advice would you give him?
Maintain intensity if nothing else
Try to exercise during transportation (cycle rather than drive)
Try to increase trips up and down the stairs
5. Why does cigarette smoking have a negative effect on maximum aerobic
Carbon monoxide displaces oxygen when oxygen is attaching to
hemoglobin. Body cannot use as much oxygen
Causes bronchiole constriction so air resistance is increased, so muscles
have to work harder to ventilate
6. An individual undergoes four months of aerobic training. Describe the
cardiorespiratory effects of this training program you would notice:
At rest (e.g., resting heart rate would be lower).
1. Reduced resting HR
2. Increased SV
3. Increase blood volume
