Specifically, superstitious reinforcement.
A player happens to grunt (or some equally meaningless vocalization) and then wins a point.
Thus reinforced, they do it again.
If they are also successful in competition (which I believe was the case) then other players will imitate them; not necessarily because of a conscious decision, but because we have a tendency (learned, genetic, or some interaction of the two) to imitate successful people.

Is the grunt that emanates when female tennis players at Wimbledon hit
the
ball
a) learned behavior
b) fixed action biological pattern
c) displaced targeted aggression
d) an aha! experience
e) other.Please explain

I suspect that their trainers have encouraged them to "grunt" as a way of
(supposedly) getting more "oomph" into their strokes. It doesn't only
apply
to female tennis players (whose higher pitch produces what I would call more like a screech) but also to several male players (though again it
doesn't sound like a "grunt" to me -- I'm not sure what to call it).
