KNPE 255 PHYSICAL ACTIVITY AND HEALTH EXAM 2025 |150
QUESTIONS WITH ACCURATE SOLUTIONS
1. If a moderately fit adult has a maximum aerobic capacity of 10 METS, what
would be the percentage of their aerobic capacity used when walking at
the same speed of 5.6 km/hr?
38%
56%
14%
27%
2. Describe how confounding can impact the results of prospective cohort
studies.
Confounding can lead to incorrect conclusions about the
relationship between exposure and outcome.
Confounding has no effect on study results.
Confounding ensures accurate measurement of exposure.
Confounding simplifies data interpretation.
3. Which of the following is true regarding breast cancer and PA
Great than 90 min of vigorous exercise is necessary for a
reduction in the risk of developing breast cancer
Some evidence suggests that the relation between the odds of
developing breast cancer and lifetime PA is different for post-
menopausal versus premenopausal women
Most studies show exercise contributes to the onset or worsening
of lymphedema
,There is a 50% reduction in the risk of developing breast cancer
with 7 h/week or greater of moderate or vigorous exercise
,4. What is the general finding regarding physical activity and endometrial
cancer risk?
No relationship found
Lower risk among active persons
Higher risk among sedentary persons
Increased risk among active persons
5. The accumulation of at least ___ minutes per week of moderate physical
activity is related to lower mortality.
100 min
75 min
150 min
250 min
6. Describe how aging affects the ability to gain muscle strength.
While we lose muscle as we age, it is still possible to gain
muscle strength, though not as much as in younger years.
Muscle strength cannot be improved at any age.
Aging completely prevents any muscle gain.
Older adults can gain muscle mass at the same rate as younger
individuals.
7. What does relative risk (RR) measure in health studies?
The average age of onset for a disease in different populations.
The total number of events in a population over time.
The percentage of individuals who engage in physical activity.
, The ratio of the probability of an event occurring in the exposed
group versus the non-exposed group.
8. What type of association exists between cardiorespiratory fitness (CRF)
and breast cancer mortality risk?
Positive correlation
Negative inverse association
Direct correlation
No association
9. If an individual increases their CRF from 4 METs to 6 METs, what impact
might this have on their risk for adverse cardiovascular events?
It will increase their risk by 10 to 30%.
It may lower their risk by 50%.
It may lower their risk by 10 to 30%.
There will be no change in their risk.
10. If a study finds that older adults have similar reductions in blood
pressure from physical activity as younger adults, what implication can
be drawn regarding exercise recommendations for older populations?
Older adults should avoid intense exercise due to potential BP
risks.
Exercise recommendations should be made without age as a
limiting factor for BP improvements.
Older adults need to engage in more physical activity than
younger adults to see BP improvements.
Younger adults should be prioritized for exercise programs
aimed at BP reduction.
