In my opinion it was poorly done and was not explained well.
Why do girls throw like girls is they have not been trained to throw like an athlete. The female glutes do not their fire the knee. It is a trained skill. Their knee works more like a ball joint and the male knee works more like a hinge as their glutes do fire their knee. The quads on a female are usually more dominate and the hamstrings are under developed creating an imbalance. Listen to a female come down the stairs and they sound very loud compared to a male. The female must be trained how to land on a flexed front knee not only for throwing however for hitting also.
It starts with balance. The female spine adjusts to the loads during pregnancy so they can adjust to the load. The male spine is tilted more forward at the sacrum for caring heavier loads. This is why you can not teach the female to stand more erect for hitting or throwing as they can not get balanced.
Notice in the clips they do not show the flex in the females front knee when throwing withe the female pitcher as they did in the male although she did it! You might want to ask how she did it and in my opinion they did not teach it or explain it well enough.
Most of our girls that are 14 years old plus throw 59 to 60 plus and do not have arm problems.
Trust me the girls can be taught and I agree throwing like a girl is an insult, especially to the coaches who do not understand how weight shift works. Poor throwing is usually carried over to poor hitting as the sequence of ground up is not fully understood.
Another point is the boys are allowed to go out into the neighborhood and play with the boys and they throw rocks, run on uneven surfaces up and down hills. The girls are not usually allowed to do that. This puts them at a disadvantage as to neurological and physiological skills per Dr. David Marshall Children's Hospital Atlanta.
Most of my girls who played baseball are the better players as they tried to emulate what the boys were doing without actually understanding what it was they were doing. Most of the girls do not even start softball until they are 9 or 10.
We use a drill called the flamingo drill and our girls catch on pretty quick as to landing on a flexed front knee.
By the way Bustos played baseball until she was 12 years old and she was a pitcher. Her Dad George sort of suggested she play softball as they would not allow her to play baseball as a girl in high school.
