Oxygen consumption during constant-load exercise.
Previous investigators have reported that oxygen consumption (VO2) continues to rise after the initial 2- to 3-min transient period of exercise when work exceeds approximately 60% of VO2 max. The purpose of this investigation was to examine the possible causes of this slow rise in VO2. Eighteen subjects exercised for 20 min at 65% and at 80% of VO2 max on the bicycle ergometer. VO2, ventilation...
متن کاملThe value of expired gas analysis is never expired.
Complications of mechanical ventilation increase with duration. Delayed weaning and premature weaning are both associated with increasing complications. In addition, adverse events and deterioration relating to the ventilator system could happen any time. Therefore, accurate monitoring of the patient’s respiratory condition and adjustment of ventilator settings are essential during mechanical v...
متن کاملEffect of inspiratory threshold loading on ventilatory kinetics during constant-load exercise.
Humoral factors play an important role in the control of exercise hyperpnea. The role of neuromechanical ventilatory factors, however, is still being investigated. We tested the hypothesis that the afferents of the thoracopulmonary system, and consequently of the neuromechanical ventilatory loop, have an influence on the kinetics of oxygen consumption (VO2), carbon dioxide output (VCO2), and ve...
متن کاملKinetics of mixed venous CO2 pressure in constant-load exercise.
We have studied the kinetics of mixed venous C02 pressure (Pi-,co2) at constant work rates of 300, 450 and 600 kpmlmin (Yano, 1986). The PVco, increased at the onset of exercise, and reached a steady state at 300 and 450 kpmlmin. However, at 600 kpmlmin, the PVco2 indicated a relatively high steady state in comparison with those at other work rates, and decreased after 5 min of exercise. This o...
متن کاملLocal Pain Dynamics during Constant Exhaustive Exercise
The purpose of this study was to delineate the topological dynamics of pain and discomfort during constant exercise performed until volitional exhaustion. Eleven physical education students were tested while cycling and running at a "hard" intensity level (e.g., corresponding to Borg's RPE (6-20) = 15). During the tests, participants reported their discomfort and pain on a body map every 15s. "...
