Applications of CPX to exercise training

One of the recommended applications of CPX from the aforementioned guidelines is to help establish the exercise prescription. The direct physiologic response to the exercise test permits a more precise target exercise intensity during rehabilitation. CPX responses can be used to optimize exercise programming considering symptoms of dyspnea the AT and other gas exchange responses. Ventilatory abnormalities during exercise described above have been used to better quantify the response to, and mechanisms to explain, improved function capabilities after training particularly among patients with CHF. An increase in VO2,at the AT after periods of rehabilitation has been described by many investigators(12,17,22,29,32,49,50), and this response has been associated with a lessening or dyspnea and perceived effort at matched submaximal levels (12.29).A number of studies in recent years have demonstrated a steeper VO2 work rate relationship, a reduction in the VE/VCO2 slope, or both, after exercise training ,indicating better cardiovascular , ventilatory, and gas exchange efficiency. Several, but not ail.

studies have demonstrated higher submaximal and maximal cardiac output responses to exercise after training in CHF (17,29,48). The higher cardiac output response have been associated with reductions in VD/VT (29),,suggesting better ventialion perfusion matching,in part explaining more efficient ventilation

in response to exercise.

For patients with pulmonary disease.non-invasive measurement of arterial oxygen saturation is now available on metabolic systems, and this measurement can provide an evaluation of exercise intensities associated with desaturation,in addition to assessing the need for supplemental oxygen .In patients with chronic obstructive pulmonary disease (COPD) training programs have been shown to improve resting pulmonary function.symptoms of dyspnea , peak VO2 and the VE/VCO2 slope, all

of which can easily be quantified with modern metabolic systems[1,20],In patients with more severe forms of COPD,various ventilatory muscle training techniques, including ventilatory muscle strength and endurance training.flow resistive breathing

training.positive pressure breathing.and other breathing techniques have shown mixed results but there is evidence of improved ventilatory responses to exercise in addition to improved maximal sustainable ventilatory capacity, ventilatory muscle

endurance ,and resting pulmonary function following training(2O),there are a number of CPX parameters that are useful in gauging the efficacy of training.First as mentioned above peak VO2 not Only provides the most accurate measure of a change in exercise capacity, but it also has been shown to be superior to other clinical, hemodynamic, and exercise variables in stratifying risk, particularly for patients with CHF [34]. Improvements in peak VO2 and other ventilacory responses after training have paralleled improved clinical outcomes in both cardiovascular and pulmonary disease []. Second, the AT increases with training and represents a submaximal measure that some consider a better reflection of a patient’s ability to perform daily activities. In addition, other CPX variables, notably the V E/VCO2 slope and VO2 kinetics, have gained interest as both functional and prognostic markers that respond favorably to training [29].
