We evaluated the late effects of multi-needy malnutrition imposed during lactation and the possible effects and / or changes to both the aging process as of moderate aerobic training on the luminal diameter and the tunica media area of the left common carotid artery, horizontal aorta and thoracic aorta of rats in the aging process. Twenty-four Wistar male rats were separated according to diet and physical training: SNG -Sedentary Nourished Group, TNG -Trained Nourished Group, SMG-Sedentary Malnourished Group and TMG -Trained Malnourished Group. At 10 months, the TNG and TMG were submitted to aerobic training in water for 8 weeks. Then the mice were anesthetized and sacrificed and the arterial fragments were collected for histological processing. The area of the tunica media was measured by the difference between external and internal areas of the arterial wall and luminal diameter was measured from the average of two diameters measured from four points marked on the internallayer of the vessel. The area of tunica media decreased in the horizontal aorta when compared groups SNG x SMG (p = 0.015) and increased in left common carotid artery between groups SNG and TNG (p = <0.001). The thoracic aorta showed an increase in luminal diameter when comparing the SMG with the TMG (p = 0.041). Multi-needy malnutrition induced both to partial changes in the horizontal aorta wall, as well as physical training was able to promote changes in the tunica media area of the left common carotid artery and luminal diameter of the thoracic aorta.
