Recently, I attended an exhibition on human physiology, and it was mentioned that the ends of our bones are more sponge like when we are growing, and this is where new bone is created. I wasn’t sure whether the comparison to a sponge was because that part of the bone is softer, or because there are many hollow cavities like a sponge.Julian Y wrote:Current coaching theory warns _heavily_ _against_ Juniors using anything larger that a 22 and goes further to recommend that even 22 is limited. The reason for this is that recoil creates significant strain with repetitive impact on the growth points of all the bones in the arm and hands. This in turn can, and has in the past, lead to permenant damage.
Anyway, the theory mentioned by Julian Y goes against much of the practice here in the USA. IPSC has its junior program, for instance, where youngsters are firing 9mm and .38 Super. I have a few questions, for either Julian or anyone else who wants to chime in.
1. Are there any published studies or literature discussing the possible injuries mentioned above? I don’t mean this as a hostile challenge, I’m geniunely curious.
2. Many IPSC competitors probably started fairly young. If these people are still competing is it because -
a. Not everyone has these problems (just like not everyone who smokes gets lung cancer)
b. In IPSC you use two hands, so that might soften recoil.
c. They have had damage, but never knew it because IPSC does not require the precision that ISSF does.
3. What is the theory regarding trap and skeet? Are these different because they are fired from the shoulder?
Thanks.
