Oxygen Uptake Kinetics During Incremental- and Decremental-Ramp Cycle Ergometry
Oxygen uptake-work rate gain incremental-ramp exercise decremental-ramp exercise system linearity
2015/5/7
The pulmonary oxygen uptake (VO2) response to incremental-ramp cycle ergometry typically demonstrates lagged-linear first-order kinetics with a slope of ~10-11 ml·min-1·W-1, both above and below the l...
VO2 Off Transient Kinetics in Extreme Intensity Swimming
Swimming oxygen uptake kinetics recovery front crawl
2015/5/7
Inconsistencies about dynamic asymmetry between the on- and off- transient responses in oxygen uptake are found in the literature. Therefore, the purpose of this study was to characterize the oxygen u...
The article “MRS evidence of adequate O2 supply in human skeletal muscle at the onset of exercise” (7) concluded that metabolic inertia—not O2 supply—is the major factor controlling the kinetics of V˙...
