EXW 344 HILL'S CRITERIA QUESTIONS WITH
VERIFIED ACCURATE ANSWERS
Select the Hill's Criterion which fits this description best: Aerobic training increases the
stroke volume of the heart and the mitochondrial density in muscle fibers. These factors
allow for more oxygenated blood to be delivered to working muscles and for those
muscles to extract and use the oxygen. This leads to an improved VO2max. - Answers -
Plausability
Select the Hill's Criterion which fits this description best: A study in China found that an
additional 30 minutes of walking per day can improve the cardiorespiratory fitness of
elderly women. A study in England found that an additional 30 minutes of walking per
day can improve the cardiorespiratory fitness middle aged men. - Answers -
Consistency
Select the Hill's Criterion which fits this description best: Distance runners tend to have
high VO2max values. It therefore stands to reason that physical activity levels across
the general population correlate positively with cardiorespiratory fitness. - Answers -
Coherence
Select the Hill's Criterion which fits this description best: People who accumulate 40
MET/hrs per week of aerobic training tend to have better cardiorespiratory fitness
compared to people who accumulate only 20 MET/hrs per week of aerobic training. -
Answers - Dose Response
Select the Hill's Criterion which fits this description best: Drug X is associated with
decreased LDL cholesterol levels, but not with decreased triglyceride levels. - Answers -
Specificity
Select the Hill's Criterion which fits this description best: The correlation between
physical activity levels and cardiorespiratory fitness is 0.5, which makes this a
moderately strong relationship. - Answers - Strength
Select the Hill's Criterion which fits this description best: A sample of 100 people is
randomly divided into a control group and an exercise group. The baseline VO2max
values of both groups are the same. After 12 weeks of intervention, only the exercise
group showed an improvement in VO2max. - Answers - Experiment
