RESUMO
To determine the effects of continuous aerobic exercise training (CON) vs interval aerobic exercise training (INT) on glycemic control and endothelium-dependent vasodilatation, 43 participants with type 2 diabetes were randomly allocated to the sedentary, CON, and INT groups. The CON and INT exercise training programs were designed to yield the same energy expenditure/exercise session and included walking on treadmill for 30 and 40 min/day, 3 times/week for 12 weeks. Body fatness and heart rate at rest decreased and leg muscle strength increased (all P < 0.05) in both the CON and INT groups. Fasting blood glucose levels decreased (P < 0.05) in both exercise groups but glycosylated hemoglobin levels decreased (P < 0.05) only in the INT group. Maximal aerobic capacity, flow-mediated dilation, and cutaneous reactive hyperemia increased significantly in both exercise groups; however, the magnitude of improvements was greater in the INT group. Only the INT group experienced reductions in erythrocyte malondialdehyde and serum von Willebrand factor and increases in plasma glutathione peroxidase and nitric oxide (all P < 0.05). We concluded that both continuous and interval training were effective in improving glycemic control, aerobic fitness, and endothelium-dependent vasodilation, but the interval training program appears to confer greater improvements than the continuous training program.

In conclusion, the present study describes a controlled series and demonstrates the safety of incidental appendectomy at cesarean section. A slight increase in operative time accompanied appendectomy group, but the length of hospital stay and postoperative morbidity were not different. It's our recommendation that at cesarean section if the abnormal appendix is found, appendectomy should be done. Normal appendix can also be removed whenever the opportunity presents in non-risk patients.
