Maybe you dont understand me. Here is the question rephrased another way. Do you think that it might be safer for vaulters if no chalk was allowed to be used on the vault runway due to the fact that sometimes it is hard to be completly removed, and could possibly confuse the vaulter????
yes, it would be safer if no chalk was used. in fact, i haven't seen it used in quite some time most places i go. velcro and tape are used. the coach just lifts/pulls it off.
now for the other problems you referred to. if the tape measure breaks away from being taped down, or the table moves away from the start of the vault runway and where that tape measure must start someone is certain to be hurt. at vault...the safety is in the math measurements from the beginning to end. and for yurchenkos, 2 inches either direction can mean the difference between landing on ones feet or face. or coming on to high or all sorts of other problems related to entry. again, these are issues that must be looked after by coaches and judges alike. imagine if the athlete, due to factors out of her control that all things listed found her hurdle line at 27 instead of 25 and her hand mat 6 inches back and the board 6 inches back, were now to find herself a math total of 3 feet back from where she normally is. now, if for the grace of god she can make it to the table from 3 feet further away, that would place her on the front of the table. it is more likely than not that this athlete will now hit the table during the post flight of her vault. and just how many of you have seen this happen? for me it is more times than i care to remember.
and i stand firm on the responsibility of the athlete. it is their job to do gymnastics. notwithstanding an obvious departure from where an individual athlete may have their bars set and they happen to notice...it is not their responsibility to notice. if athletes had to worry about if their equipment was set straight away they all would need medication. understand? again, the sacred trust between athlete and coach. and if the athlete is standing 75 feet away, and the judge raises the green flag, you can not expect the athlete to guage whether their hand mat is in the correct place, or that their board is in the correct place, or that the tape measure broke away and they can't see that from where they stand or that the table is 6 inches away from the vault runway. understand? they are sprinting down the runway at an average of 12 miles an hour and have a miniscule moment in time to perform their yurchenko layout full or whatever. you can't just 'pull up' once you commit. and gymnasts are taught not to pull up and execute to the end. this is one of the primary safety nets ingrained in gymnasts so that they DON'T become injured. this is well known, published and understood in the coaching community and says as much in the safety manual. to not practice this time honored safety technique would then lend itself to the practice of 'balking'. and ALL of you must be aware of the inherent safety concerns as it relates to balking, yes?
and gymster...i'm glad that this post did not get pulled. this is important stuff for all. turns out it went downthread to page 2 and i didn't see it right away.
and gymdog...the kids should know their bar settings, vault settings, etc; in the event that they are separated from their coach as you described. shame on that coach for accepting the responsibility of another athlete and failing to follow thru. unacceptable! this means that it is their job to ensure that everything is where it belongs.
