Čtverný skok, nebo ve sportovním slangu čtverák, je figura v krasobruslení s alespoň třemi, ale méně než čtyřmi otáčkami.[1] Většina čtverných skoků má 3 a půl otáčky; čtverný axel má 4 1/2 otáčky, ačkoli žádný krasobruslař nedokončil tento skok v soutěži. Čtverný toe loop a čtverný salchow jsou dva nejčastěji skákané v této disciplíně. Čtverné skoky jsou stále častější mezi jednotlivými krasobruslaři na světové a olympijské úrovni, a to do té míry, že neskočení jednoho v programu je považováno za vážný handicap.[2][3] První osobou na světě, která zvládla čtverný skok a byl schválen, byl kanadský krasobruslař Kurt Browning v roce 1988. V roce 2002 se Miki Ando stala první ženou, která zvládla čtverný skok a zůstává jednou ze dvou žen, kterým byl v soutěži skok schválen.

Historie prvních skoků[editovat | editovat zdroj]

V singlové soutěži mužů:

  • Žádný čtverný axel zatím nebyl schválen.
  • Žádná kombinace čtverných skoků (čtverný skok následovaný čtverným loopem nebo toe loopem nebo jakákoliv kombinace čtverných skoků) nebyla zatím uznána.

V soutěži žen:

  • 14. prosince 2002 ve volné jízdě ve finále Junior Grand Prix v Haagu v Nizozemsku Miki Ando ustála prvního uznaného salchowa v soutěži.
  • 10. března 2018 ve volné jízdě na mistrovství světa juniorů v krasobruslení v Sofie, Bulharsko, Alexandra Trusova skočila první uznaný čtverný toe loop v soutěži. Dále jako druhá žena zvládla čtverný salchow, jako první žena zvládla dva čtverné skoky v jednom programu a dva různé tipy čtverných skoků v programu.[11]
  • 7. září 2018 ve volné jízdě na Junior Grand Prix v Kaunasu, Litva, Alexandra Trusova jako první žena zvládla kombinaci se čtverným skokem v soutěži, skočila čtverný toe loop a vzápětí trojítý toe loop.

Execution[editovat | editovat zdroj]

A jump harness is often employed in training quads.[85] Max Aaron stated that the smallest error may make the difference in the success of a quad attempt: "The minute your left arm is behind you, or your three-turn is too fast, if your hips don't turn in time, if your foot isn't in the right place, anything will throw you off."[85] Ross Miner stated that the quality of the ice sometimes plays a role but more on the quad salchow than the toe loop.[85] Practicing quads increases the risk of injury as well as wear and tear on a skater's body.[85][86]
