OAP LEVERS & TORQUE 單引力臂與力矩
Let's discuss how we can adjust the one-arm pull-up to make it as efficient as possible. To simplify this we take a look at two different things from one perspective, which leads to the 'strange' way the loading arms are marked. Note that this is more a qualitative way to look at it, it's not showing the real dimensions.
讓我們一起探討如何更有效率地調整單手引體動作(以下簡稱單引)。在簡化這個動作之前,我們來用同一個觀點看這兩個不同的作法:這樣做會導致承重手(圖中有標記)呈現一個「奇特」的姿勢。請注意這是用一個更有品質的方式去觀察這個動作,而非呈現真實的尺寸。
重要單字:
Torque U/n. 力矩
Discuss vt. 討論
Adjust vt. 調整
Efficient adj. 有效率的
Simplify vt. 使簡化
Perspective C/n. 觀點、看法
Qualitative adj. 品質上的;性質上的
Dimension C/n. 維度;尺寸
縮寫解釋:
OAP = One-arm Pull-up 單手引體向上
LEVEL OF HORIZONTAL ARM ADDUCTION (FRONT VIEW) 上臂水平內收的程度(前面觀)
I know want you to imagine you are looking from the left side of the picture to the front side of my body. The less my arm is horizontal adducted, so the bigger the distance of my elbow to the line of force is, the longer the force arm is. A long force arm means we need to produce more force to move the same weight.
我想讓你去想像你正在從左邊這張圖,正面看我的身體。我的上臂水平內收的程度越少,我的手肘與拉力線(黃色虛線)的距離就越長,力臂也就越長。一個長距離的力臂意味著,在相同的重量下,我們需要用更大的力氣去移動。
重要單字:
Level C/n. 高度;數量;能力水準;樓層;力臂(這個字也有形容詞與動詞的解釋,但在這邊以名詞的「力臂」解)
Imagine vt. 想像(You cannot imagine + 子句… 你無法想像(強調))
Horizontal adj. 水平的
Adduct vt. 內收(向身體中線移動,名詞為Adduction)
Distance U,C/n. 距離
Produce vt. 製造,產生
Force U/n. 力(在此作為名詞解)
Weight U/n. 重量
LEVEL OF HORIZONTAL ARM ADDUCTION (SIDE VIEW) 上臂水平內收的程度(側面觀)
Now just take a look at the picture as it's taken. By opening up the angle between our elbow and body, so by using less horizontal addition (adduction), we are increasing the leverage on the elbow and so we are putting more stress on our arm flexors. Also from the side view, you can see, that the upper arm gets 'shorter' which creates an advantageous load arm.
現在來看這張圖,藉由打開我們的手肘與身體的夾角、減少水平內收,我們增加了手肘的槓桿作用,因此我們放更多的壓力在我們的手肘屈肌。同樣地從這個角度,你能發現上臂變得「較短」,讓手臂創造出一個優勢的承重狀態。
重要單字:
Open up 打開
Increase vt. 增加
Leverage U/n. 槓桿作用
Flexor C/n. 屈肌(例如肱二頭肌,那麼相對來說叫做Extensor 伸肌,如肱三頭肌)
Advantageous adj. 有利的,有優勢的
Takeaway:
if you want to make oap's (OAP’s) efficient and do them with minimal force output, keep your pulling arm close to your body. Advanced athletes can use this concept the other way around to increase the difficulty of this element.
簡化版:如果你想讓單手引體有效率,並且用最少的力量輸出以達成這個動作,讓你的承重手接近你的身體。進階的運動員能夠使用這個觀念來增加困難度。
重要單字:
Minimal adj. 極小的;極少的;極簡的
Output C/n.; vt. 輸出
Advanced adj. 先進的;高等進階的
Athlete adj. 運動員
Concept U/n. 概念
Difficulty U/n. 困難度
Element C/n. 元素
