The oxygen cost of the treadmill speed and grade was calculated using equations commonly applied for predicting oxygen uptake from treadmill and cycle ergometer work. An example of the ramp test is illustrated in Figure 1. With the exception of the protocol, all exercise data, including hemodynamic, gas exchange, and perceived exertion were collected as…
Exercise Testing Each subject performed 2 exercise tests. They were requested to abstain from food, coffee, and cigarettes for at least 3 h prior to testing. The first test was performed to familiarize subjects with the testing procedure and gas exchange apparatus, and to determine maximal oxgyen uptake. This test consisted of a modified Balke…
A test that facilitates this approach is the ramp test, in which gradual changes in work can be individualized considering the patient’s age, fitness, disease status, and the purpose of the test. Recently our laboratory compared individualized ramp treadmill and cycle ergometer tests with commonly used standard protocols. Ws noted that the slope of the…
The quest for an “optimal” test for assessing electrocardiographic and/or gas exchange responses to exercise spans 7 decades. Several protocols have evolved that have become common, and while the treadmill is the most frequently used mode in the United States, the cycle ergometer remains popular in Europe. Advantages and disadvantages of various exercise modes and…
