【奧林匹克式舉重動作不能捨棄的理由】
分享《The System: Soviet Periodization Adapted for the American Strength Coach》書中對奧林匹克式舉重的看法。該書的作者們並沒有否定專項訓練的重要性,但強調現階段(美國許多力量教練)用其他動作「取代」奧林匹克式舉重是不智的作法,主要的理由是上膊和抓舉能訓練到「大範圍動作」與「全身性」的「爆發力」與「速度」。下面附上原文、我的譯文和懸垂式上膊的訓練側拍影片:

近年來,隨著人們越來越重視力量訓練中的安全性,以及所謂的「專項力量」訓練,奧林匹克式舉重動作已不再受到許多力量教練的青睞。主要的理由是,如果運動員不是要參加奧林匹克舉重比賽,有更好的爆發力訓練動作可以選,它們更容易轉化為運動賽場上的成績,而且這些動作不用移動那麼大的重量,所以對身體的壓力與風險會低很多。
為了甩開風險,有許多擲藥球或更有創意的動作已經在許多運動團隊的力量課表中取代上膊、抓舉、挺舉。在我們看來,這個鐘擺甩得太遠了,這些動作一直都能培養出世界上最強、最具爆發力運動員,現在卻要完全捨棄,實在太過極端。
我們要瞭解奧林匹克式舉重動作的主要目的是:通過「大範圍的動作」(特別是下肢)在全身產生最大的爆發力。
專攻奧林匹克式舉重選手和特別注重專項力量訓練的選手,這兩者的訓練課表,你最常發現的區別是:舉重選手是透過大範圍且快速的動作來訓練下肢;換言之,後者的動作幅度大都比較小。很多教練出於善意,使用了許多替代舉重的練習動作,但這些練習並沒有辦法達到舉重動作所需的柔韌性、協調性與力量輸出。
使用奧林匹克式舉重動作可以訓練到關節在較大彎屈幅度時的爆發力和穩定度,那也是身體在賽場上可能會碰到的幅度。(譯者註:當然對純跑者和泳者來說就並非如此了,不過自行車選手和大部分的球類運動相當符合)
一位運動員在進行完整的抓舉、挺舉時,如果進步太快或是沒有經過正確的指導再加上大重量,的確會導致受傷。但所有的訓練動作都是這樣,只要進階太快、操作不當或重量太重都會受傷,所以問題不在動作,而在於教練沒讓運動員準備好。
像美式足球或籃球這種運動的動作幅度很大,執行動作時需要高度的柔軟度與力量;在提升這些能力上,奧林匹克式舉重動作會比擲藥球的訓練更有效率。這些動作並不危險,只要你能先評估他們的身體是否有能力安全完成這些動作,事先對舉重動作進行規劃與指導,以及循序漸近地增加重量和動作難度,那麼很多顧慮都會消失。
當你能有效且適當地進行奧林匹克式舉重訓練,你會發現它的好處遠遠大於缺點。
(但作者也強調並不是每個人一開始都適合練奧林匹克式舉重動作)
一開始先別進行大量且高強度的奧林匹克式舉重訓練,最好先等到運動員們至少已經練了幾年之後才能大量的練。如果他們在早期要發展爆發力,可在運動員學習和改善舉重動作時先進行「跳躍」與「增強式訓練」。
無論什麼動作,練熟了動作的技術之後,接下來「速度」是第一位。雖然體育界很重視力量和肌肥大,但力量所表現出來的速度才是真正分出運動員實力差異的關鍵所在。
在健力(powerlifting)比賽中,動作的速度並不重要,目標是舉得更重,不管花多長時間,比賽結果只看重量。但在美式足球場上,最強壯的線鋒球員若不能迅速將力量轉化為控制對手防守球員的能力,他們就不能算是成功的進攻組球員。同理,一位能肩推數百磅重的鉛球選手,如果他不能用全身的力量來加速擲出鉛球,他也將無法把獎牌帶回家。

#原文如下
THE OLYMPIC LIFTING CONTROVERSY
In recent years with the increasing emphasis on safety in strength training and what is termed “sport specific” training, the Olympic lifts have fallen out of favor with many strength coaches. The argument is that if you are not competing in Olympic lifting, there are better options for training explosive strength that translate more readily to sports performance, without the risks and strain inherent in rapidly moving heavy weights.
Variations of medicine ball throws or more creative exercises have taken the place of cleans, snatches, and jerks in the strength programming of many teams as coaches try to reduce those risks. In our opinion, the pendulum has swung too far away from using the movements that have consistently produced the strongest and most explosive athletes in the world.
The main goal of the Olympic lifts is to generate maximal power and explosive strength in the entire body through large ranges of motion, particularly for the lower extremities.
The differences you will most often find between the training regimen of an Olympic weightlifter and of athletes performing more “sport specific” training are that weightlifters consistently take the lower extremities through high-speed, large range-of-motion exercises. Many of the substituted movements and exercises used by a well-intentioned strength coach do not come close to demanding and developing the flexibility, coordination, and force output demanded by the weightlifting exercises.
It is true that subjecting an athlete to a full snatch or jerk with a substantial amount of weight without the proper instruction or progression will often result in injury. However, that holds true for any exercise. It is not the fault of the exercise, but rather the coach’s fault for failing to prepare the athlete to succeed.
Dynamic sports like football or basketball require suppleness and strength expressed through large ranges of motion; the Olympic lifts are more effective at facilitating those qualities than a medicine ball toss. If you assess an athlete to be physically capable of performing the movements safely and if the lifts are programmed and coached effectively and progressed in both weight and complexity, many concerns diminish.
You will discover that when implemented effectively and appropriately, the benefits of the Olympic lifts far outweigh the drawbacks.
A significantly high volume of Olympic lifting is best left to the athletes with at least a few years of training under their belts. For developing athletes such as these, the power and explosive qualities can be addressed through jumping or plyometric training as the Olympic lifts are coached and refined over time.
After mastering technical efficiency and form, no matter what the movement, speed should always be the priority. Although strength and muscle hypertrophy are important in the world of sports, the rapid expression of that strength is what separates athletes on the field of play.
In the sport of powerlifting, the speed of the movement is not critical. The goal is to lift the maximum weight, however long it takes. On the football field, the strongest linemen will rarely succeed if they cannot rapidly translate that strength to control an oncoming defender. A shot putter who can military press hundreds of pounds will not take home a medal without the ability to explosively accelerate the entire body to throw the shot.

台灣最大公約數 – 反共去統不反中
The True Common Denominator of Taiwan
我察覺到一個新的台灣共識(最大公約數)正在成形,而且已經接近完成。雖然許多人還沒意識到這點,也還有一些人尚處在無感、或雖然有感但心理上拒絕的階段。
I sensed a New Taiwan Consensus is forming and near completion, although many are still not fully aware of it, some at the psychological stage of ignoring it and some even in total denial .
這新共識可以用三個原素的一句話來總結:反共、去統、不反中國平民。三元素環環相扣,構成了一個具有主旋律的直白命題:那些已經把台灣視為自己家鄉的人,已經把台灣當成一個與他方無涉的主體。
This New Consensus can be summarized in one expression with three parallel elements: opposing communism, de-unification and neutralness toward Chinese civilians. These three elements constitute an organic whole with a common theme that simply says, people who took Taiwan as their home deemed themselves as one distinct entity .
為了讓人們充分理解這三元素的意義,需要做一些進一步闡釋。我們這就開始。
I understand some elaboration may be needed to allow the three elements to be fully appreciated, especially the third one. Let me begin.
1. 反共。台灣其實並沒有那麼反對自由的社會主義;事實上,台灣社會本身在日常生活型態中就含有明顯的自由社會主義的痕跡。但是,台灣絕不會容忍社會主義精神脫序到共產主義的地步。若然,那種社會主義就是敵人,沒有討論的餘地。台灣海峽彼岸的中國共產黨(CCP),就屬於這一類。
1. Opposing Communism – Taiwan is not that much against liberal socialism. In fact,there is a rather obvious strain of it already existing in its social life. However, Taiwan would not tolerate socialism when carried away to the extent of communism, and would take it as enemy. Period. Chinese Communist Party (CCP) on the other end of the Strait falls into this category.
2. 去統。在台灣,不但老一輩了解中共天天掛在嘴邊玩弄的「統一」,只不過是其用來維持政權、控制已經被洗過腦平民的一種虛偽口號,而年輕一輩只會以荒謬視之。因而,此處並沒有用過去的「反統」一詞,而是用「去統」,表示了一種將「統一」概念徹底由腦中去除的意思。就像「大掃除」的意思一樣,老早就該扔掉的東西就把它扔掉。
2. De-Unification – Not only do the older generations realize that the jingling of
“unification” of the CCP is just a bogus slogan for upholding its regime’s control
over the brain-washed civilians, the young generation of Taiwan simply finds the
slogan ridiculous. Therefore, rather than using the term “anti-Unification” as people used to do in the past, I think “De-Unification” – the unshackling of the very idea of unification, as one can relate with the word “de-clutter”- is a better suited term.
3. 不反中,指的是對中國平民保持中性的態度。過去三年間,包括我自己以及國際輿論,已經破除了那個存在已久的迷思 – 中共CCP就等同中國。情況根本不是這樣的。中共不等同中國,更不用說等同中國人民了。中共是一個具有9千8百萬黨員的巨大政黨,但那只是住在那塊土地上的14億人當中的7%。
3. Neutralness towards Chinese Civilians – In the past three years, people in Taiwan including myself, as well as the international community, have debunked the long-existed myth that CCP Is China. No, far from it. CCP is NOT equivalent to China, let alone the Chinese people. CCP is a huge party of 98 million members and that accounts for only 7% of the 1.4 billion Chinese people living on that landmass.
簡單的算數就可以呈現真相。對任何國家,如果僅佔7%的人口可以在政治上完全控制100%的人口,唯一的可能就是實施殘酷暴力或通過暴力改變人的頭腦。
Simple math would tell the truth. In any nation, when 7% of the population politically controls 100% of the population, it would be an impossibility unless by brutal violence or total brain coercion.
中國平民本身就是受害者。其他的國家,不應該膝蓋反應式的把受害者視為天生就是邪惡的。因此,無論在心態上還是現實地緣政治考慮下,台灣社會都應該把「必反」這詞留給共產黨而不是受害的平民。
Therefore, considering the Chinese civilians are victims themselves, people from other parts of the world should not act in a knee-jerk way towards the ordinary, victimized Chinese Civilians as if they are born evil. Either under a proper mindset or the practicality associated with geopolitics, Taiwanese society should and is starting to understand this point. “Anti-“ is an attitude reserved for CCP and not intrinsically for the ordinary and mostly victimized civilians.
這才是台灣的最大公約數。然而,為了選票的政治人物及民調機構拖累了台灣。每年每月的民調都在問早已失效的問題:你偏藍還是偏綠?你贊成獨立還是統一?
Putting together the above three Elements, thus there is the New Taiwan Consensus. What’s falling behind and dragging Taiwan’s feet, are the ballot-hungry politicians and the various outdated polling agencies. They do so many so-called popular surveys every year, sometimes monthly. And they stick to the long invalid way of setting up their survey questions: Are you favoring Green (DPP) or Blue(KMT)? Are you pro-independent or Pro-unification?
這種自我設限或自我審查的問法,使得其他國家以為台灣是個分裂社會。
This kind of self-confined or self-censored surveys leave other nations the impression that Taiwan is a split society, Green or Blue, Independence or unification etc.
台灣這種導致外人認為台灣是個分裂國家的作法,實在愚蠢。如果問的問題對,台灣是沒有分裂的。例如,如果將「你贊不贊成獨立」改為「你反共不反共」,結果肯定是98%以上。
It’s such a foolish thing to do for Taiwan itself misleading outsiders into deeming Taiwan as a split country. There is absolutely no split should the right questions be asked in the surveys. For example, had the question been changed from “Are you pro-independence or anti-independence” into “Are you pro-communism or anti-communism”,then the result would have been a clear-cut 98% or even 99.5% towards “anti”.
若問「你是反中國共產黨還是反中國老百姓」,前者不會低於80%,後者不會高於20%。
Now, try this further question: “Are you anti-Chinese Communist Party, or anti-Chinese common people”, my guess is the former gets at least 80% and the latter gets 20% at most.
第三個問題:「你願不願意被共產黨統治」,保證結果是99.9%的「不願意」。
The third question: “Would you be willing to live under the Communist Rule”? That would guarantee a resounding NO answer of 99.9%.
這就是新台灣共識、社會的最大公約數,應該向世界大聲、清楚、不含糊的說出來。
This is exactly how the New Taiwan Consensus looks like – the true common denominator among a seemingly divided Taiwan. And the New Taiwan Consensus should be articulated to the rest of the world, no vagueness, no grey area and unambiguously.
不信的話,可以用上述問題做幾次民調。而且我保證,在不久的將來,所有民主國家都會端出類似「台灣共識」的政策原則。
For any surveyor or politician who still has doubts about this New Taiwan Consensus, he or she can just conduct new surveys with questions suggested as above. And, I myself am convinced, in a not-so-distant future, all democratic countries on the planet would issue national policies based on guidelines similar to the New Taiwan Consensus, for the goodness of their respective countries.
所以,台灣為什麼不這樣做呢?這可是台灣展示世界政治領導力的機會啊!
So, Hey, Taiwan! Why not put a thrust on this Taiwan Consensus to the world by publicizing it unambiguously and show some political leadership, just for once?
後記:以雙語向全球發聲,將是我接下致力的方向。所使用的這兩種文字,涵蓋了35億人口,接近地球的一半人數。這個行動,將以 「前哨預策」網站 為核心基地,其他的社交媒體,只要有傳播力道,都會被用為衛星來做整體運作。
個人的思考、判斷不一定對,您也不見得同意,但是,我保證這平台中的每一句話都是獨立的、出自內心的。而今天的台灣,乃至於世界,最缺的就是突破傳統成見、不受黨派左右、同時又知錯能改的獨立思考力量。不知您是否同意?
「前哨預策」平台將分為三步走:內容平台 – 互動平台 – 行動平台。剛誕生的它,當前還只是個內容平台,但達到一定數量的會員支持後,將加入各種新媒體形式,與會員就重要議題互動,並以「達成不同意見之間的最大公約數」為目標。一旦在會員內部形成「最大公約數」後,就構成了行動的基礎。至於行動的形式,也由願意推動或參與的會員決定。
此平台婉拒任何政黨、政府的贊助,只接受個人會員或企業會員的贊助;所有收入及贊助,均將用於「讓台灣更好」的事務上,以及推動、發揮台灣作為東亞及世界的「關鍵少數」的槓桿角色,為人類下一波文明做出量力而為的貢獻。
我只能說,十年來的不斷保持獨立,希望能換得您對「不受任何政黨、政府左右」這一點點價值的認同。

true strain 在 Cara G McIlroy Facebook 的最佳貼文
This whole covid bullshit is so hard on relationships mine included. It may look like everyone is breezing through this year without a care in the world sometimes but I’m here tell you most are not.
Social media can really warp reality in that way and that’s not all bad. I in most parts use this platform to uplift people (with the occasional emotional breakdown 😂) sharing the happy aspects of my life. I get so many messages everyday about how my feed and stories makes people’s day. How they can’t wait to see Freija clowning around or me baking bread, India dancing and Noa just being a cutie. This brings me so much joy that I’m able to put smiles on people faces and fill their hearts with warmth. I live for that. Now more than ever with so much going on people need joy. There is another world though, the one that exists off screens and there are battles there. This period has been and still is one of the hardest times Jesper and I have been through in almost 15 years. Not because we are not in love. Don’t be mistaken I love the shit out of this incredible man but daily I also wanna kill him. Living in a house where we are a family of 7 , working from home, home schooling ect is killer. Even the strongest relationships are feeling the strain. I wanted to share this incase you are going through the same thing. To let you know you are not alone. To tell you your love will get you through this even on the days you think it’s not enough. Maybe I’m saying this out loud as therapy for myself. The point is that this is true love. Love that can survive through anything is worth holding onto. Thing’s weren’t meant to be easy, that would be so boring ( although I wish they were sometimes)
There will be awful days but they will pass and beautiful moments will fill those spaces between. I’m grateful for each and every up and down with you @jespermcilroy ....
