ABSTRACT
PURPOSE:
The aims were to (1) compare peak oxygen uptake ([Formula see text]peak) predicted from four standard equations to actual [Formula see text]peak measured from a cardiopulmonary exercise test (CPET) in obese patients with metabolic syndrome (MetS), and (2) develop a new equation to accurately estimate [Formula see text]peak in obese women with MetS.METHODS:
Seventy-five obese patients with MetS performed a CPET. Anthropometric data were also collected for each participant. [Formula see text]peak was predicted from four prediction equations (from Riddle et al., Hansen et al., Wasserman et al. or Gläser et al.) and then compared with the actual [Formula see text]peak measured during the CPET. The accuracy of the predictions was determined with the Bland-Altman method. When accuracy was low, a new prediction equation including anthropometric variables was proposed.RESULTS:
[Formula see text]peak predicted from the equation of Wasserman et al. was not significantly different from actual [Formula see text]peak in women. Moreover, a significant correlation was found between the predicted and actual values (p < 0.001, r = 0.69). In men, no significant difference was noted between actual [Formula see text]peak and [Formula see text]peak predicted from the prediction equation of Gläser et al., and these two values were also correlated (p = 0.03, r = 0.44). However, the LoA95% was wide, whatever the prediction equation or gender. Regression analysis suggested a new prediction equation derived from age and height for obese women with MetS.CONCLUSIONS:
The methods of Wasserman et al. and Gläser et al. are valid to predict [Formula see text]peak in obese women and men with MetS, respectively. However, the accuracy of the predictions was low for both methods. Consequently, a new prediction equation including age and height was developed for obese women with MetS. However, new prediction equation remains to develop in obese men with MetS.Palabras clave
