Oxygen uptake efficiency slope as a useful measure of cardiorespiratory fitness in morbidly obese women.

摘要: Cardiopulmonary assessment through oxygen uptake efficiency slope (OUES) data has shown encouraging results, revealing that we can obtain important clinical information about functional status. Until now, the use of OUES not been established as a measure cardiorespiratory capacity in an obese adult population, only cardiac and pulmonary diseases or pediatric patients. The aim this study was to characterize submaximal maximal levels sample morbidly women analyze its relationship with traditional measures fitness, anthropometry function. Thirty-three (age 39.1 ± 9.2 years) performed Exercise Testing (CPX) on treadmill using ramp protocol. In addition, anthropometric measurements function were also evaluated. Maximal measured, being calculated from obtained first 50% (OUES50%) 75% (OUES75%) total CPX duration. one-way ANOVA analysis, did significantly differ between three different exercise intensities, observed Bland-Altman concordance 58.9 mL/min/log(L/min) OUES75% OUES100%, 0.49 mL/kg/min/log(l/min) OUES/kg75% OUES/kg100%. A strong positive correlation (r = 0.79) 0.81) OUES/kg consumption at peak (VO2peak) ventilatory anaerobic threshold (VO2VAT) observed, moderate negative hip circumference -0.46) body adiposity index -0.50) verified. There no significant difference OUES, showing correlations each other (peak VAT). These results indicate be useful parameter which could used cardiopulmonary fitness subjects severe limitations perform CPX, for women.
