A fair number of them do, actually. Many of the kicking forms like Taekwondo, Muay Thai, and other forms of Kickboxing are really good for women because they teach one to use the full body. The joint lock disciplines are also excellent, because joint locking relies on leverage, accuracy, and body placement, not physical strength.
Women are also very good at wrestling because of their lower center of gravity, which once mastered, can be used to destabilize their opponents. One of the physical female advantages is having a lower center of gravity than their male counterparts as a simple part of their physiological makeup. You have to learn how to make your body work together to take advantage of it though.
Female power comes from the center and below the waist (which doesn’t negate the upper body) by focusing on martial arts that focus on those things (which is most of them) and having an instructor who won’t handicap his or her female students by forcing them to fight one way instead of adjusting their teaching style to the students technique.
Techniques will only get you so far to learn well one needs a good instructor. Also, learning how to think and fight with the entire body is important. I wish I could say that it was as simple as just a physical match up of statistics, but it’s not.
