Table 2. Peak oxygen uptake and oxygen uptake kinetics for peak and submaximal treadmill test.

Variable Control (n = 25) HF (n = 25) P-value
Maximal treadmill test
 VO2peak, mL/kg per min 22.5 ± 1.2 12.9 ± 0.7 0.0001
Submaximal treadmill test
 VO2peak, mL/kg per min 7.4 ± 0.3 7.2 ± 0.3 0.57
 tcdeficit 29.9 ± 3.6 60.0 ± 8.3 0.002
 tcEPOC 33.8 ± 3.1 52.2 ± 3.8 0.001

Data are presented as mean ± SE. tcdeficit: lag in oxygen uptake at the beginning of exercise (oxygen deficit); tcEPOC: excess oxygen uptake above rest following exercise (excess post-exercise oxygen consumption); VO2peak: peak oxygen uptake.
