[The effect of endurance training on the neovascularization of skeletal musculature].
OBJECTIVE
To quantify the capillaries in the skeletal muscular tissue of mice with induced peripheral arterial insufficiency, after endurance training.


METHODS
It was used Wistar mice in 70 days age range, subjected to the total occlusion of right femoral artery. The animals were divided into two groups: sedentary group (SG; n = 05), subjected to activities in the cage; and trained group (TG; n = 05), subjected to an endurance training in cycle ergometer twice a day 17m/min, by 5 minutes, 5 days per week during 10 weeks. The analysis was realized by the histologic observation of the vastus medialis muscle of injured member.


RESULTS
The average number of capillaries in the muscular tissue was greater in TG (5,2 +/- 0,83) than in SG (1,6 +/- 1,14) (p < 0,05).


CONCLUSIONS
In animals with induction of peripheral arterial insufficiency, the endurance training provides a process of muscular adaptation which is observed by the increase in the number of capillaries of animals subjected to this kind of training.
