【力量訓練的「訓練量」該如何設定?】
跑者的訓練量俗稱「跑量」,單位是「公里」,所以月跑量三百是指一個月總訓練距離300公里。在力量訓練圈的「訓練量」(Training Volume)常是「總反覆次數」 (Total Repetition)的同義詞;而「月總量」就是指一個月的總反覆次數,像我們會建議初跑者的月跑量最好不要超過100公里一樣,在做重訓時,有沒有一個區間可以讓大家參考呢?下面是《The System》的作者群建議:
#以下為譯文:
以剛接觸訓練的新手來說,月總量最好從750次(總反覆次數)開始;而菁英運動員的上限設在1,600次。在前蘇聯時代,我們親眼看到他們運動員以更高的月總量進行訓練。然而,我們後來也發現這跟他們使用加強運動表現的補給品有關,那使運動員能更快恢復。
總反覆次數是指在單一個週期中(這裡是指中週期)所有基本力量動作重複次數的總合。因此總反覆次數750的意思是在不同的訓練強度與動作中總共累計的次數,但這個數字不包括輔助訓練的動作。
從帳面上來看,750這個數字分配到一個月十二到十六次課表當中,看起來似乎很小,但我們這們所定的750這個數字比較像是「基本量」,而非下限,如果總反覆次數低於750下,就不會為運動員的成長帶來實質的影響。表 4.14 中的數值並不是意味著高水平或菁英運動員在四週內的總反覆次數永遠不會有低於1,000次情況發生,那只是維持成長的基本量。對運動員的恢復能力影響最大的是訓練量,因此這些範圍中比較需要注意的是上限的數值。若月總量超過上限值,恢復能力將快速到受到侵害,而且侵害的速度比任何其他因素都快。
一位菁英水準的運動員可以在一個月的時間裡完成1,000次以下的訓練,就算在恢復期也經常發生。然而,訓練新手若超過1,000次的上限,大都要承擔受傷或嚴重過度訓練的風險。
許多教練擔心他們的運動員練不夠,所以無法有效獲得力量和爆發力的進步。他們不想因為目標定得太低而有所保留,這讓他們感覺是「浪費」了一個月的訓練時間。剛開始採用這個方法來訓練時有這種感覺很自然,我們系統中的每一位教練也都曾經歷過相同的掙扎。
美國的力量教練已經把「訓練要用盡全力」當作一種信念,訓練完還有餘力好像就會覺得不夠認真。但請相信我們。我們說的方法很少失敗,也幾乎沒有過度訓練的風險,這些區間已被證明能最有效地幫助運動員進步。
在調整運動員的訓練量時,需要考慮到他們的技巧、經驗、過去的醫療史、訓練史、性別、實際年齡與訓練年齡。
我們過去的慘痛教訓可以讓你少走許多彎路。當你在訓練量的拿捏上猶豫不決時,原則是寧少勿多。寧可因量太少沒進步,也不要犯下過量訓練的錯誤。
總訓練量不包括輔助訓練或是特別針對「局部效果」的練習次數。那些動作主要是為了強化特定肌肉或是使全身力量動作能做得更好的輔助性訓練,所以我們不會把它們算在總訓練量中。
最受我們重視的力量訓練動作不只對身體的負擔很大,技術要求也很高;正因如此,我們才會嚴格限制訓練量。
雖然輔助訓練不會被計算在總訓練量裡,但你不要因此失控,開始加練很多你想練的輔助動作。永遠記住:效率第一。
#原文如下
The absolute floor of volume for a novice athlete is 750 total exercise repetitions per month, and the ceiling for the elite athlete is 1,600 total reps. During our time in the former Soviet Republics, we witnessed athletes performing even higher monthly training volumes. However, as we found later, that was often with the benefit of performance-enhancing substances that allowed for more rapid recovery.
In a single cycle, the total number of repetitions pertains to all exercises performed in the key movements. This means 750 total repetitions are spread between the different exercises among the range of training intensities we want to emphasize.
On the surface, these can seem like small numbers when we consider they may be spread out over 12 to 16 training sessions. That 750-rep total is really more like the basement rather than the floor of total volume—any less than 750 will not budge the needle on gains. That does not mean advanced or elite-level athletes will not have cycles that dip below 1,000 reps. These ranges should be more prescriptive of the ceiling of higher volumes to avoid exceeding. Pushing monthly volume beyond these ranges erodes recovery more rapidly than any other factor.
An elite-level athlete can use a month with a total volume of under 1,000 reps, as will often be the case when returning to training. However, a novice athlete can rarely exceed the 1,000-rep ceiling without risking an injury or a significant overtraining effect.
Many coaches worry their athletes will not do enough work to promote gains in strength and power. They do not want to “waste” a month by aiming too low on total volume and leaving some gains in the tank. That is a natural feeling when adopting this method, and each of us went through the same mental struggle.
Strength coaches in America are not hard-wired to accept less than maximum. However, trust us when we say that without fail, these ranges have proven to be the most effective in generating progress with almost no risk of overtraining.
Fine-tuning where your athletes fall in a volume range takes skill, experience, and consideration of their medical and training history, biological and training age, and gender.
The bloody trail of our mistakes can save you a lot of added stress: When in doubt, it is always better to err on the side of less volume than too much.
The total volume number does not include accessory work or exercises of “local effect.” Those exercises are more targeted muscle strengthening or exercises to support the main movements.
We are mainly concerned about the most physically taxing exercises that demand more of an athlete’s attention to technique—hence, the volume restrictions.
Although the accessory work is not included in the volume calculations, you still cannot go wild, adding as much as you want. Always remember this: efficiency first.

🌻Morgan Stanley Mid-year Investor Outlook: A tricky transition
https://www.morganstanley.com/ideas/midyear-2021-global-markets-outlook
🌻在您投資生涯中, 有沒有一些觀念讓您受用很多?
下面這位投資名人的好觀念影響我很深. 他的意思是, 一般投資人, 只要能説出三個買一家公司的理由, 就很夠了. 這也迫使我, 每次在買股票時, 問自己對這家公司的了解有多少. 也會去衡量公司的優點與缺點在哪裡.
"It is vital (重要的) that you know what you own, that if I asked you on the street why you like a certain stock, you can give me three reasons. If you don't know how they make their money, who their key clients are and what they make if, then I will tell you that you are over your head and should not own individual stocks."
全文在此:
Jim Cramer: In Times Like This, Go for the Easy Money
Look at the stocks you own. Can you tell me why you've got them? If you can't answer the following three questions, then have a look at several I like right now.
We've endured the meme stock craziness, with all of its love for heavily shorted stocks. We have watched the collapse of bitcoin to levels viewed as shocking, even if they are still more than double where they were not that long ago. We've dealt with Fed officials making it clear that they are no longer on the side of the bulls or the bears. They are on the side of job growth, but are wary of inflation. We've seen the end of the rush to get vaccines, which means that millions of people are going to get the new COVID variant, because there is no natural immunity to it. We've watched as the hopes for an infrastructure bill have collapsed. We've endured shortages of everything from chips to plastic to imported goods and labor.
And we're still standing, yeah, yeah, yeah.
Yep, we are in one of those halcyon moments, where the masks are off -- even if they shouldn't be -- and Americans are back doing what they do best: consume, spend, go out to eat and then consume and spend some more.
There are times in the stock market where the collective mindset is revealed. This is one of those times: Things are cool, it's not a big moment, there's no real news for a bit, it's the historically strong period and we can reach some conclusions about where we are.
When things are like this, it is important to remember that buyers like to revert to tried-and-true companies that thrive no matter what. These are companies that have an edge and are better at what they do than other companies.
You know that I am a great believer in index funds, that the average person doesn't have the time or the inclination to research individual stocks. It's a difficult barrier. I think you need to make time to read the quarterly report and listen to the conference call, to Google articles and, if possible, get some research about the companies you own. It is vital that you know what you own, that if I asked you on the street why you like a certain stock, you can give me three reasons. If you don't know how they make their money, who their key clients are and what they make if, then I will tell you that you are over your head and should not own individual stocks. I am reminded by this, because, once again, without a mask, I can be recognized and if I am not holding "Nvidia the Second," I can carry on a conversation.
I have had many in the last two weeks and when I have asked this litany of questions, I find myself at a loss as to why almost no one knew what they owned. But they thirsted for individual stocks, because they, like me, think things are better post pandemic. No, that's not a facetious comment. Many, many stocks did better with a stay-at-home economy. A huge number.
So what do I do? I revert to what others do when you are stumped about how to stay in touch with stocks, but want to do less homework. That means buying stocks that are accessible, not stocks like Unity (U) or Snowflake (SNOW) or Twilio (TWLO) or Okta (OKTA) .
I revert to normal businesses people know and I suggest they Google some articles, peruse the conference call, but, above all, like the company's products so you can buy more if it goes down.
Here's some that I have been telling people I like:
First is Ford (F) . I think the Ford lineup is amazing. The electric F-150 series will be incredible. I am eager to get a Maverick for my family, because it is a smaller pickup that will get the job done for the myriad little things I need to do with this farm I bought from that crazy bitcoin foray. I like the competitive edge of the CEO, who says he is going to bury Elon Musk when the Lightning comes out. I even think the Bronco is cool as all get out. Most important, though? I think the chip shortage is ending. My semiconductor friends are telling me the foundries are producing more feature-rich chips and that means Ford can pump out the trucks small business people love and need. Plus, the used car prices at last have plateaued, according to their most important pricing index. Halcyon times.
Second, Costco (COST) : The samples are coming back. Tell me you don't love the samples. You need things in bulk. You want low prices. You want to get all of the things that people don't think of with Costco, like insurance, hearing-aids -- hey, they are a fortune -- jewelry, things around the house. You go and you will buy far more than you first came for. My kind of store.
The kids love this American Eagle Outfitters (AEO) , which we just bought for my charitable trust, which you can follow along by joining the Action Alerts PLUS club. Jay Schottenstein, the CEO, came on "Mad Money" recently and it's clear that his Aerie model has real staying power: 26 consecutive quarters of double digit growth. No flash in the pan, that one. Number one brand in jeans for the 15 to 25 year old group. The best in the mall. How did I know this? I see the credit card bills.
I got up this morning to do my physical therapy. I have been doing it ever since I hurt my back in February. I have this really cool pair of sneakers that fit me perfectly and I love them, but I am fortunate enough to have a vacation house and I am always taking those shoes with me.
So I went on Amazon (AMZN) this morning and lo and behold I saw them for half price. I bought two pairs. Then I went over everything I have bought in the last year and got a bunch of those things. Then I bought a pair of binoculars, because mine were stolen. I paid half price.
Yep, Amazon's universal. I was talking to Alexa, while I was ordering, getting some new music on, asking questions. I saw that despite all of the Sturm und Drang of Amazon being late with things, all the delivery dates were within range. I didn't click on any ads, and I didn't need the speed of Web Services, but the whole thing reminded me about how special the darned company is. I don't care if it's ahead or behind plan for the moment. I would just buy some more when it goes down.
Finally, Apple (AAPL) . I think people who don't own Apple should look what they are holding at this very moment. Yes, right now. Or look at what's in your lap or on the table besides your fork. And then think about the bill you paid last night without knowing it. Think about what you bought in the App store yesterday. Think about what would happen if it would break or get stolen or, left in the Uber (UBER) , or heaven forbid, be dropped into the pool or in the, yes, toilet.
There, that's what you buy in halcyon times. Stocks of companies you know that if they go lower, because things get less halcyon, you are fine with it and buy more. If things go up, believe me, you will participate.
So accept the moment. Don't try for the hard money. Go for the easy kind. That's the best kind.

【絕食第80日】【80th Day of Hunger Strike: Update & Volunteers' Thoughts】

▍「除了停止了探訪外,這裡任何東西都沒變過。廁所依然是那麼髒,他們(入境處)連一塊香皂都沒有多給我們。」- 羈留者O生氣的說
自9月6日CIC出現第二單新冠確診,CIC便停止了探訪,所有羈留者都已經十天因探訪暫停而無法獲得一些基本衛生護理物資。以下為義工H的心聲:
CIC對認可物資要求十分苛刻,書一定不要有任何標註,連一個「由XX中學圖書館捐贈」的印章也容不下,「呢本唔入得」;香皂只能是藍色的,但藥房通常是一排六塊的賣,只有兩塊是藍色,總有四塊紫色、白色不知如何處理;以為只要寫著「祝君早安」的毛巾便可以,買到了,職員又說「標誌中一的不是「合」字,這不是正版」,退回,不收;買了兩包M&M想給羈留者,但被告知一次一定要給5包,而且一定要是同一顏色的包裝。第一次聽到時會又生氣又無奈,明明都是香皂、毛巾,這些要求除了用來留難訪客,有任何意思嗎?每次探訪,更是總會見到其他訪客有一些東西因不乎要求而被退回,山長水遠走到來CIC,卻沒法送物資到親人、朋友手上,會感到很可惜嗎?
怒氣與無奈,隨著探訪次數漸多而慢慢地被磨蝕。為了能順利地把物資送到羈留者手上,更是練成了一對金精火眼,去到不同藥房都認得出物資,知道格價合理與否。這一陣子,見到任何藥房都會逛一逛,見到適合的便買下。這幾天都接給幾位羈留者的電話,有的說急需牙膏、香皂(只能通過探訪才能獲得),有的說很悶想收新的書。我想說,我都準備了,只是不知何時才見到他們。
羈留者的來電中,讓我除了知道他們需要的物資外,更是體會到自由對他們的迫切。「7樓的40多人全被送到隔離營了,你有他們的消息嗎?」S問。「我需要幫助。我不想繼續留在CIC,這裡有新冠病毒確診。這裡不安全。」R說。我想這次CIC這次確診引致的Lockdown和全院檢測已充份反映到這個地方十分高危,為何還是要強行把一班無罪的人拘禁,置他們的健康生命於危險中?
「我們差不多所有羈留人士已經聯名向入境處寫了一封投訴書,抗議停止探訪並要求交代原因。」O說。「希望很快可以容許探訪。」
▍“I am very angry about this lockdown. They (ImmD) did nothing more to advance any prevention or protection measures. Just lockdown. We are running out of toothpaste, soap and hand wash.” — Detainee I
Due to the discovery of the 2nd confirmed case of COVID-19 on 6th September, CIC has suspended all visit. All detainees have since been unable to receiving basic hygienic products from their visiting friends. It has been 10 days. Below are some thoughts of our volunteer H:
CIC is exceptionally meticulous, or better put, bureaucratic about the hand-in articles from visitors to detainees. A book must be totally clean, even a stamp that says “Donated by XX School Library” would made the book ineligible for handing in; The soap must be in blue, yet stores often sell this brand of soap in a pack of six, so volunteers would always be left with 4 bars of non-blue soap; when you bought the towel with the exact wording, the staff will always let you know that your towel is “knock-off” and therefore unaccepted; M&M must come in 5 packs of the same colour. When the articles I bought first got rejected by CIC officers, I was very frustrated. In terms of their function, the towels and soap I bought were just fine. And every time I visited, I always saw other visitors’ “unapproved” articles got rejected. Imagining coming all the way with the hope of giving a little something to make your detainee friend’s life slightly better, and yet got rejected for the bureaucratic instructions of CIC, would you feel upset?
Nevertheless, my angry and frustration has been numbed as I visited CIC more frequently. In order to successfully got the articles to detainees, I have become an expert. I have memorised the entire list of approved hand-in articles and know the prices for each item. And over time, I have stocked up these articles for the detainees. In the past few days, our concern group have received several calls from detainees, saying that they are lacking certain hygienic project. “We are running out of toothpaste, soap and hand wash.” they said. I would love to let them know that I have stocked up, yet I now have no idea when I can give things to them due to the lockdown in CIC.
From these calls from detainees, not only had I learnt about the certain items they need, but also what freedom meant to them. “40 detainees from 7/F have been sent to the isolation camp, do you have any news about them?”, detainee S asked me. “Actually I need help. I don’t want to stay long time in CIC. There is positive case here. CIC is not safe.” Detainee R said. I think the current lockdown of CIC have demonstrated exactly how CIC is not safe. There is a high risk for cross-infection of COVID-19 in CIC. So, why is the authority so determined to detain this group of innocent people, and put their health and lives in danger?
“Most detainees have wrote a complaint letter together to the Immigration Department against the lockdown and ask for reasons.” Said O. “Hope this complaint letter could help reopen visit soon.”
