A tic-tac involves using an obstacle to "gain position" on another obstacle. For instance if you want to jump over a wall that is too high, but there is a bench you can jump to first, then you could "Tic-Tac" off the bench to clear the wall. A Tic-Tac can also be done off a wall to change direction or to clear an object that couldn't be cleared from the ground. This technique is commonly used to overcome a low object or gap, to vault a higher object, or leading into a cat leap.
三角跳
三角跳是一種利用一個障礙物去幫助穿越另一個障礙物的技巧. 譬如說, 你需要跳過一道高到你無法直接跳過的牆, 但是牆前面有一個你跳得上的矮板凳, 那你就可以從板凳上三角跳過這道高牆. 三角跳也可以用在一道牆上來改變方向或是跳過一個從地上跳不過的障礙物. 這個技巧一般是用來跳過一個較低的障礙物或深溝, 跨越一個較高的障礙物, 或是緊接著進入一個貓抓的動作.
首先, 以差不多45度角跑向一道牆; 眼睛看著牆上的著腳點. 你並不需要跑很快; 只要小跑步就可以了. 你跑向牆的角度越大 (越接近垂直), 你在牆上的那一步就會越扎實. 反之, 你跑向牆的角度越小 (越接近平行), 你沿著牆橫向的距離就可以達到越遠.
單腳從地上跳起, 同時將另一隻腳往牆的方向伸. 身體稍微朝牆反向傾斜以免撞上去. 在不犧牲穩定度的前提下試著在牆上踩越高越好.
當你的前腳接觸牆時, 大部份的重心應該放在腳掌上. 當你起跳的那隻腳開始向前時, 就開始用牆上的那隻腳吸收動力. 但是, 小心不要吸收太多否則反彈出來時就會沒有力量. 還有, 你腳在牆上的角度會因你三角跳之後要做的動作而有變化, 但是一般來講它應該會在 9 點鐘到 12 點鐘之間的角度.
眼看著你的降落點, 一腳用力踢牆同時將另一隻腳再你前面彎曲升起. 把身體拉起; 確定落地時身體與地面成垂直狀. 三角跳往往可以給你更多高度與距離, 所以試著把它當作一個 "跳出" 的動作而不是一個 "跳下" 的動作.
落地時, 確實記得所有落地共通的要領: 將雙腳向地面延伸然後 (1)吸收動力直到蹲姿; 或(2)在地面上滾動後繼續前進.
First, run towards the wall at about a 45 degree angle while looking at the spot on the wall where you will place your foot. You don't need a lot of speed; a brisk jog is fine to start out. The greater the angle the more "stick" you will have to the wall, the shallower the angle, the greater distance you will cover across the wall
Leap off the ground with one leg; the other leg extended up towards the wall. Lean away from the wall slightly so you don't just run smack into it. Try getting as high up as possible on the wall while maintaining a solid step.
When your front foot makes contact with the wall, most of your weight should be on the ball of your foot. Begin absorbing as your leaping leg comes forward but don't absorb too much or you will take a lot of the punch out of the leap down. Also the angle of your foot on the wall will vary depending on what comes after the tic tac but generally the direction of the toes will range from 9:00 to 12:00.
Looking at your landing spot, kick off the wall powerfully while bringing your other leg up bent in front of you. Also, straighten your body up to meet the ground vertically. The term "leap down" is a little misleading because you can often get additional height and distance, so think of it as more of a leap out.
Follow the steps for any good landing, extending towards the ground to absorb into a crouch or prepare to roll and continue on your way.
