A lot of this is akido based, and therefore judo and jiujitsu based. As someone who trained akido for over 3 years I can tell you that a lot of the techniques shown are virtually useless in real life. The untrained opponent can be manipulated pretty well to a point, but basic and quick is always best. Spinning around in wasted movement will get you hurt or killed really quickly.
As far as if women can learn these techniques, I see absolutely no reason why not. But, that said if I were directing a woman, or anyone for that matter, to an unarmed self defense training I would suggest you seek out the best legit MMA (mixed martial arts, or UFC as it is often mistakenly called) or Brazilian Jiu-jitsu gym in your area and put in a ton of hard work. Having trained AKido, Judo and boxing in the past and having trained Brazilian Jiu-jitsu and limited MMA for the last 2+ years I have gained anew perspective on self defense. Anyone can be trained to incapacitate a much larger/stringer untrained opponent in only a few weeks of quality training. Case in point, after training for several months and being a big strong guy, 6 foot 235 lbs with long athletic background, I was quite easily choked into submission my a 40+ year old women who had been training for roughly a year. It's a humbling experience, but I never underestimate people anymore.lol
Knowing how to put the combination of grappling, striking and defense together makes a huge difference in your ability to quickly end a conflict. I wish more people who choose to carry a firearm would take unarmed self defense as seriously as they do armed defense.
Sorry for the long post.
