The Yurchenko double pike versus the Yurchenko double twist : a theoretical comparison of landing decelerations

Rood, Samantha (author)

This paper theoretically examines the factors that most affect the average deceleration experienced by an elite level gymnast upon landing either a Yurchenko double twist (YDT) or a Yurchenko double pike (YDP) on vault using real input data. Five factors were evaluated: the gymnast’s height, vault height, flip time, twist time, and landing time. This study analyzed all vaults performed during the 2023 Xfinity U.S. Gymnastics Championships in San Jose, CA, on August 25th and 27th to determine reasonable ranges for the five noted variables. Landing time was found to have the largest effect on the landing decelerations. Lengthening the landing time from 0.12 seconds to 0.3 seconds theoretically reduces the G-forces experienced on landing from 6-8 G’s to approximately 2 G’s. Further research is needed to confirm these theoretical results.

• Title: Preskok dvojni Jurčenko sklonjeno v primerjavi z Jurčenkom z dvojnim obratom : teoretična primerjava blaženja doskoka

Abstract

Članek proučuje teoretične dejavnike, ki najbolj vplivajo na povprečno blaženje, ki ga doživi vrhunska telovadka pri doskoku preskoka Jurčenko z dvojnim obratom (YDT) ali dvojni Jurčenko sklonjeno (YDP), pri čemer so uporabljeni dejanski podatki resnične izvedbe obeh preskokov. Ocenjenih je bilo pet dejavnikov: višina telovadke, višina mize za preskok, trajanje premeta, trajanje vrtenja v letu in trajanje doskoka. Raziskava je razčlenila vse skoke, izvedene med ameriškim telovadnim prvenstvom v San Joseju v Kaliforniji med 25. in 27. avgustom 2023, da bi določila razumne razpone za zgoraj omenjene spremenljivke. Ugotovljeno je bilo, da ima trajanje blaženja največji vpliv na ustavljanje pri doskoku. Podaljšanje časa blaženja z 0,12 sekunde na 0,3 sekunde teoretično zmanjša G-sile, ki delujejo na telovadko pri doskoku, s 6–8 G na približno 2 G. Za potrditev teh teoretičnih rezultatov so potrebne nadaljnje raziskave.
