NCT03182712

Brief Summary

The aim of this study was to verify the effect of a combined supplementation \[n-3 PUFA (known to induce anti-inflammatory effects) plus vitamin E (known for its antioxidant properties)\] on lipidic, glycemic, redox status and inflammatory parameters in type 2 diabetic patients. In addition, considering that exercise, at high intensities, can induce a transient inflammatory state and increase oxidative stress (OS) markers, the investigators tested if our nutritional intervention could attenuate this response within this population (thus, using high intensity exercise as inductor of acute inflammatory/OS state).

Model Details: The selected subjects were referred to the University laboratory. During their first visit, the subjects were submitted to perform the first high intensity sub-maximal test. In the same day, volunteers received the supplementation capsules that should be taken throughout eight weeks, as described in the supplementation section. The subjects were randomly assigned to two groups: (1) group placebo and (2) n-3 PUFA group. After the supplementation period, all subjects reported back to hospital to biochemical testing and thereafter to the university exercise laboratory for the second high intensity sub-maximal test, following the same protocol described above.
