Background and Purpose: Oxygen uptake efficiency slope (OUES) is an index for evaluating cardiorespiratory fitness without performing maximal exercise and correlates well with the individual's peak oxygen uptake (□O(superscript 2peak)). The purpose of this study was to determine the clinical usefulness of OUES for determining the cardiorespiratory fitness of obese adults without cardiovascular diseases by investigating (1) the correlation between OUES and weight (2) the change in the OUES after a weight-reduction program. Methods: Fifty-eight obese subjects (13men and 45women) were enrolled in a 12-week weight-reduction program, including diet, exercise and psychological programs. They underwent maximal cycle ergometer exercise testing, …
