I wouldn't say advantage but my experience is that women have greater aptitude for Wudang sword which is often subtle and indirect.
(For this reason it is also important to train in Shaolin sword if starting young enough, for its emphasis on building physical strength, and techniques such as aggressive thrusts and lunges, even if lunges are not recommended for historical fencing.)
- Wudang fencing heavily relies on the concept of "inviting your opponent's blade" by letting it get within a few inches of your body.
This allows more decisive counters, and the best strike in swordplay is the safest—not an initial thrust, hoping to hit before your opponent reacts, but having countered definitively, such that a riposte can be delivered with no possibility of reply.
As footwork and posture can be said to be even more crucial in wudang sparring than other internal arts b/c swords can be instantly fatal, having more grace, lower risk tolerance, and even some dance training, is a huge asset, speaking as a teacher, both in terms of poise and flexibility.
- Women have been shown to be slightly more risk-averse on average, which is a huge advantage in any contest that can be instantaneously lethal.
(Sometimes women students have trouble making cuts like they mean it, but they typically have better basics than the guys.)
Here's a video of Cheng Man-Ching doing an internal fencing exercise designed to develop "sticky" (maintaining contact with the opponent's blade to control it and counter decisively) and teaching intention (swordplay is the channeling of intention through body and blade.)
Although sword sparring comes mostly to wrist cuts, point fighting, and occasional wave counters, having developed the stickiness and intention shown in the wudang fencing video is ever more essential.
FIE fencing, because of the use of non-combat weight weapons, and lack of consequences for getting hit, clearly makes pure speed definitive in competition, but HEMA longsword suggest that historical weight weapons can mitigate that advantage.
Wudang is advantageous here because it utilizes the waist, not arms, to make "drawing" cuts, thus lower strength shouldn't be a factor. Waist is also use to power and enhance the power of a variety of cuts and thrusts and counters, pretty much everything. As for cuts which purely rely on wrist strength, it doesn't require all that much to slice into skin and flesh with a sharp edge.
- Speaking as someone who trained under a master 5' tall, lower center of gravity is definitely an advantage is countering (deflecting to gain advantage)
At least in this style, which is close fighting, and, aside from the primary technique of wrist cuts, prefers to attack from inside.
In the recent HEMA program, Knight Fight, which featured armored melee, hip throws were a regularly applied technique, and lower center of gravity can be definitively advantageous in grappling.
If I lock blades with someone down by the guard, putting them on the ground is my goto. (Wudang fencers typically spend as much or more time practicing grappling in the form of tai chi & bagua as they do on blade training.)
