I think it can help train the muscles of the back and neck to keep your head under severe overloads in flight.
Because when coming out of a peak, inertia will pull her head down.
I also sometimes saw in books and movies how a character wears weights all the time to train his muscles. And it’s very epic when, in the middle of a fight, the character removes the restraints and begins to act with full force.
That makes sense, the weight training reminds me of Dragon Ball^^
