You throw like a girl

This year I have noticed that several of the kids on my oldest son's baseball team don't know how to throw. Although some can still throw it far and fast their form is horrible. This is something learned rather than inborn.
My youngest (who doesn't play) and I where playing catch before practice last night. I've been trying to help him develop a decent throwing form. While he isn't much into sports, I could tell he was really thinking about his form and the instructions I was giving him. Several times he made some really good throws and catches too. His friend showed up (the younger brother of a player), and I asked him if he wanted to go play with him. I knew he would want to and I wasn't going to make him stay there and play catch with me. He said he did want to play with him, but "after one more catch". It took a couple of tries but he did end on the positive note of having made one last catch. In contrast, when playing catch with my oldest son, at some point I usually have to say OK, I've had enough I'm too tired. After two hours or more it wears me out.
For kids in sports proper form is important for many reasons. In games that require throwing, it can cause great strain on the elbow, especially pitchers. Like most things proper form is for safety and optimal function.
I'm not sure how the term "you throw like a girl" started, but if you look at women's sports today it would be a compliment. There are many video clip examples of throwing,kicking and hitting techniques for various sports and yes, even books, imagine that. So even if you can't throw, try to give your child instruction on proper form for their benefit and self esteem. Nothing worse than playing school yard baseball or softball and being criticized by other children about the way you throw.
