Introduction: Obesity is considered one of the main health problems of modern society, there are several treatments to reverse it, being bariatric surgery (BS) the most effective method in cases of severe obesity. Cardiorespiratory fitness (CRF) is an aspect of physical condition assessed through maximum oxygen consumption (VO2max); the kinetics of VO2 is a less studied aspect of CRF; it has been described that this variable allows estimation of the CRF without high physical efforts in comparison with other forms of evaluation; In spite of the above, there is no information regarding the impact that sleeve gastrectomy (SG) has on the CRF evaluated through this variable. Objective: To determine the impact of SG on the VO2 kinetics of women with obesity. Material and method: Quasi-experimental study, 15 women with an age of 32,9 ± 10,3 years and an initial BMI of 35,2 ± 3,9 kg/m2 participated. The sample is non-probabilistic through a group of volunteers evaluated at three times: before surgery (pre), 30 and 90 days post vertical gastrectomy (30post and 90post respectively). Body weight, body mass index (BMI), waist circumference (WC), VO2peak and VO2 kinetics were evaluated. Results: After surgery, the variables body weight, CC and BMI reported a significant decrease (p <0,001) compared to the pre-surgery moment. The relative VO2peak (ml/kg/min) increases between 30post and 90post (p <0,001); the absolute VO2peak (L/min) decreased between the pre moments with 30post and pre with 90post (p <0,05); the kinetics of VO2 showed an increase in time at 30post (p <0,05). Conclusion: The VO2 kinetics is increased in obese women undergoing SG at 30post surgery, which shows a deterioration of this capacity.
