Residential building code requires the use of cross bracing or blocking for floor joists exceeding 2 inches by 12 inches but many homes especially older ones have.
Even if your joists already have a row of bridging at the center of the span adding a row on each side of the existing bridging will stiffen the floor.

When the joists twist they pull away from the subfloor sheeting and the structural integrity of the floor is compromised. Bridging or x bracing allows joists to share weight. True floor joist span calculations can only be made by a structural engineer or contractor.
