Yes it does. greater oxygen consumption and greater oxygen deficit after exercise must be compensated after workout. There are also other reasons vasodilation occur. With different intensities You can usually see greater artery diameter and longer time of vasodilation with higher intensities of resistance training. 

For example You can look at this study by Van Beekvelt et al. :

I hope it will help.

Hello Henrique

I agree with Jan

The research shows that the amount of nitric oxide, increases more than 13 times after 1 h  of physical activity (aerobic or resistence training) in consequence of shear stress. Nitric oxide is a potent vasodilator released by the endothelium which pIay a

pivotal role in maintaining vascular homeostasis.

Hi Henrique, with increased work one can think of different scenarios. i.e. it may be increased intensity or simply increased volume. By way of increased intensity, yes with  more muscle recruited or recruited to a higher level, one may suggest that blood flow is increased. However, acutely. i.e. during the contraction, if it is of high intensity, you may in fact restrict blood flow. Also one can imagine that with increased volume, there may well be an increase in body temperature, this also would affect the blood flow kinetics as well as the other factors that have been mentioned ie nitric oxide release. If you think about it when the engine (muscle) demands more fuel by way of either intensity or volume increases, the way the body supplies it is to increase supply i.e. increase blood flow to those tissues that need it

It depends of the type of your resistance training, and also your population. For sure, the effect of interval resistance training among recreational weight lifters will not be same with effect of split patterns of resistance training among bodybuilders. In plus, intensity and load of resistance training are very important to predict the physiological parameters. 

In general, I am agree with previous answers, but I am not sure if this increasing in blood flow is significant in all types of resistance training.

Hamdy and Stephen, gave you very good references.
