There were fist fights?
Janeway running around pretending to be Ripley in Macro Virus showed that if the scripts told hr to be action girl that Kate could carry the issue.
Apart from the boxing episode? Chuckles was always the peace maker because Janeway was insanely violent starting wars with everyone they met.
It took 6 years for me to see Tim Russ do some Kung Fu in Gravity and I lept for joy utterly.
Voyager just didn't have that much bare knuckles violence.
