create > conserve > convert. Convert as much energy as possible to the vault itself.
actually, each athlete has an optimal speed of run. Not all are fast enough to handle their maximum run speed.
visual – what do they see?
rigid body
shapes at each phase
tempo, rhythm
arms as straight / tight as possible on Round-off
knees as straight / tight as possible on the Springboard
hips up quickly on the preflight
head watches the board before preflight, but eyes watching hands on contact
watch the horse on post-flight. (Lifting the head too soon can later cause early twist problems.)
Extending the hips while on the Springboard generates rotation through an indirect reaction force of the feet on the board. Nick has gymnasts train backward layouts on Tramp without using the arms — requiring them to use hip extension to generate rotation.
Gainer backward layouts would be an alternative to this, requiring hip extension on takeoff.
Note that Nick doesn’t actually show the full Yurchenko vault. As Edouard Iarov first made clear to me, once the hands leave the horse it’s too late to change height, distance or total rotation. The flight phase is more related to trampoline basics than vault.
Here’s some advice on what to do when allowed to reopen sports facilities. It’s quite general, information for coaches of all Olympic sports.
USOPC Return to Training Considerations Post COVID-19
Phase 3:
small groups allowed to train. But no general public access.
athletes, coaches, and staff have NO symptoms of COVID-19 (Appendix 2) in the past 14 days
anyone who had a case of documented COVID-19 infection needs a note from their doctor indicating they are cleared to participate in training
ideally participants should have 2 negative COVID-19 tests separated by 24 hours before resuming training
athletes record signs and symptoms (including temperature) on a paper or electronic log that is monitored by coaches or staff
athletes interviewed each time on arrival for symptoms
athletes should use their own equipment and avoid touching each other as much as possible
Use own water bottle, towel, personal hygiene products, etc.
Rigorous, frequent cleaning schedule/protocol of equipment with disinfectant before, during, and after training
cleaners wear appropriate personal protective equipment (e.g., gloves, face mask, etc.) to prevent contact with contaminated surfaces and protect against toxicities associated with cleaning products
coaches maintain physical distance from athletes, as much as possible. No spotting, if possible.
Lorraine Currie of Futures Gymnastics in Canada has organized an interesting event — an online Gymnastics Congress.
The theme …
Resilience 2020
Five days – May 11-15, 2020.
Cost is low:
$15 for any one stream: Business, Competitive, Recreational
$25 all access.
Proceeds going towards COVID-19 vaccine research at University of Pittsburgh and Sunnybrook Hospital.
Many big name presenters whom I’d love to hear. This is a COVID-19 alternative for coaches who normally book themselves for one of the annual Congress events.
