Optimizing the exercise protocol for cardiopulmonary assessment
Why the study?
Does the choice of ergometer and work rate increment affect maximal O2 uptake and anaerobic threshold during cardiopulmonary exercise testing in normal men?
Population
12 normal men
Comparison
1-min incremental exercise tests to exhaustion… vs Comparison between treadmill and cycle…
Design
Other, Randomized design for the work rate increment comparison

Implication
Modality and duration may influence CPET values in healthy men; leaves open standardization for clinical populations.
Structured PICO
Does the choice of ergometer and work rate increment affect maximal O2 uptake and anaerobic threshold during cardiopulmonary exercise testing in normal men?
P
Population
12 normal men
I
Intervention
1-min incremental exercise tests to exhaustion on treadmill and cycle ergometer with various work rate increments
C
Comparator
Comparison between treadmill and cycle ergometer, and comparison of different work rate increments (treadmill: 0.8-4.2%/min; cycle: 15-60 W/min)
O
Outcome
Maximal O2 uptake (VO2 max) and anaerobic threshold (AT)surrogate
For optimal cardiopulmonary exercise testing, work rate increments should be selected to bring the subject to exhaustion in approximately 8 to 17 minutes.
