Underwood has shared this pole vault cheat sheet. It was compiled by John F.
Shirley, Pacific Association. Rich
Schornstein is a Master Official from Colorado. He has shared the following to
help working: High Jump, Pole Vault and Clerk's areas. Check
the Pole Vault Preps page for Custom Bar Lifters
by Chris Marcellus of the South West Track Officials Association. I have a pair
and they are great! Fellow
High Jump Officials,
I have attached the latest issue of George
Kleeman's newsletter on track and field equipment and
specifications. The reason you are getting it is that one of our high jump
friends - Dan
Moy of Illinois - did a study on the force needed to dislodge a crossbar with
the "sag" up versus with the "sag" down. It is an interesting study,
but doesn't definitively answer the question. Below is my response to Dan. I
thought you would find the study interesting. I would appreciate any comments
you have on it. Mike
Armstrong (Arkansas)
************
(using
the data in Dan's study):
Example of bar with sag down:
Height in middle - 2.00 meters, height at ends - 2.02 meters, height at one
meter from each end - 2.01 meters.
Example of bar with sag
up: Height in middle - 2.00 meters, height at ends - 2.00 meters, height at one
meter from each end - 2.00 meters.
In my thinking, though
the bar would be more stable with the sag down, unless the athlete jumped
directly over the middle of the bar, he/she would have to jump a higher height
- as much as 2 cm higher at the end of the crossbar and 1 cm higher half way
down the crossbar.
So the question becomes, which is the
greater liability: lower height with less stability or greater height with more
stability. Dear
Coach or Potential Coach:
You will find the information regarding my annual
USATF
Level I coaching school at UNC.
It will be held December 12-14, 2008.

For more information log on www.usatf.org/groups/Coaches/education/ INSURANCE - MEMBERSHIP - CERTIFICATION As most of you know by now, Liability Insurance is scheduled to be in effect for Officials who also are members of USATF, starting on 11/08/08. This benefit was approved at the 2007 Convention where membership for officials was also overwhelming approved by the Officials in attendance. The cost of this policy will be borne and payment will be processed by USATF in Indianapolis. The bottom line here is the fact that membership will be required in order to be eligible for the Liability Coverage provided by USATF. Certification will not be valid once the expiration date on you membership card has been reached. Certification Chairs will be processing certifications and recertification documentation as usual but will also be requiring that you provide your membership number with your request. Membership can be purchased on an annual, two, three and four year basis with respective discounts with increasing years. You may however provide membership number information on a yearly basis to the certification chair. Should you have any questions regarding this matter please contact your Association's Certification Chair. The details of the Insurance Policy and the Proposal have been posted on this site. Final wording and other particulars are being worked out in Indianapolis. This coverage will not , as rumored, cost you, the official, another $10. USATF is picking up the cost. Further expansion of the Membership Benefit Package is also underway. Further details regarding contacts and appropriate action to be taken should an incident arise, will be provided shortly. The NOC Insurance Committee appreciates all your input and wishes to thank all those who so kindly provided their support to bring this effort to a successful closure. Bob Tice, Chair - NOC Insurance Committee |
