Does blocking add strength?

I am considering blocking my deck in which I am putting a hot tub on. The 2x10 joists span 12' out from house. I am putting 3 posts with 4x6 beam directly under the tub and was curious if blocking would add additional support, or if it was just to prevent twisting.

The blocking is there to prevent the joists from twisting.
