Is physical activity or aerobic power more influential on reducing cardiovascular disease risk factors?
Why the study?
Does higher aerobic power or physical activity reduce cardiovascular disease risk factors in adults?
Population
1,664 law enforcement trainees, including a subset of 576 low-fit adults (VO2max < 30 mL.kg-1.min-1)
Comparison
Higher aerobic power and physical activity… vs Lowest tertile of VO2max and PA; low-fit…
Design
Cohort
Follow-up
9 weeks

Implication
Higher VO2max may aid cardiometabolic risk stratification; leaves open whether fitness gains reduce risk factors in prospective trials.
Structured PICO
Does higher aerobic power or physical activity reduce cardiovascular disease risk factors in adults?
P
Population
1,664 law enforcement trainees, including a subset of 576 low-fit adults (VO2max < 30 mL.kg-1.min-1)
I
Intervention
Higher aerobic power (VO2max) and physical activity (PA) levels; 9-week exercise program for low-fit individuals
C
Comparator
Lowest tertile of VO2max and PA; low-fit individuals who did not increase VO2max after the exercise program
O
Outcome
Cardiovascular disease risk factors (total cholesterol, blood pressure, smoking, and obesity)surrogate
Aerobic power (VO2max) is more strongly associated with reduced cardiovascular risk factors than self-reported physical activity levels, and improving VO2max through exercise reduces risk factors in low-fit individuals.
