Objectives: This study investigate the effects of a high intensity interval training (HIIT) and 2 weeks of detraining in functional and body composition parameters, lipoproteins, glucose metabolismand inflammation markers in postmenopausal women with metabolic syndrome (MS). Design: 17 untrained women with MS underwent a HIIT program for 12 weeks. Methods: The training was performed in treadmills, 3 days per week, with intensity ranging from 70-90% of the maximum heart rate (HRmax) and 2 weeks untrained (inactive). Functional and body composition parameters were evaluated before and after the training, while maximal oxygen uptake, lipoprotein and inflammation markers were analyzed before, after training and also in detraining. Results: The HITT program resulted in changesparameters as glucose, HbA1cand NOx after training. In addition, a reduction in pro-inflammatory interleukins and an increase in IL-10 after the HIIT program were found. However, an increase in plasma levels of lipoprotein was found and body composition parameters remain unaltered.Besides, only 2 weeks of detraining are able to revert the effects on inflammatory parameters afforded by the HIIT program. Conclusions: The HIIT program used here positively affected inflammatory profile and other parameters, as glucose, HbA1cand NOx, on postmenopausal women with MS. Moreover, 2 weeks of detraining can reverse the beneficial effects of HIIT program. Our results point out the necessity to aply acontinuous HITT program, in order maintain the benefits detected, to post menopausal women with MS.
