This probably stupid question but I heard something for the 1st time the other day. I was told that if a pitcher is also playing volleyball that she should taking pitching easy while she is playing volleyball. Problems with the shoulder could arise if she is pitching at top speed during volleyball season. I have never heard this before but after I did. I remember that my DD complained of her shoulder being sore last winter, she had never had any shoulder soreness before, but last year was her 1st year of volleyball. I guess this makes sense I am just not sure why or why I had never heard this before. Is this something I should be concerned about?
