We've been new to our gym (a little over 2 years) and to gymnastics as a whole. There has been problems within our gym and about 2/3 of our gymnasts have left. There are so many rumors and bad mouthing that went around at our gym, it is hard to tell which way is up. Of concern to me right now is that our equipment is outdated and can cause injury to our gymnasts. Visually, it is obvious that our vault is getting thread bare and so is the trampoline. We also do not have any pits. There is also talk about our floor being "cracked" in some places. Some have claimed landing on these cracks and straining/spraining their ankle. Apparently, a parent complained and all management did was "nail it down"--whatever that means. I know my dd has said certain parts of the floor is much bouncier than other parts. With unhappy parents telling their own experience and these stories getting passed from one person to another, the accuracy or validity becomes questionable. It is also hard to go to the owners as they do get offended and I don't know if they would even admit to this if it were true. Can anyone tell me (1) what is underneath the floor and could there be a concern based on this story; and (2) which apparatus, equipment (including mats, spring boards, tumbletrack, etc.) have a limited life and need to be replaced, or checked, or updated on a regular basis. Thanks for your help.
