【家庭醫學】~ 靜態伸展/動態伸展 (Static and Dynamic Stretching)

最近的演講中，有人問到這個問題，而且發現與會者們都很有興趣；本來還以為很多人都知道了，現在拿出來分享一下。

先來簡單定義一下靜態和動態伸展吧：

※ 靜態伸展 (Static Stretching)

靜態伸展，應該是我最早接觸到的伸展，從小學體育課老師都這樣教 (你看看有多OLD SCHOOL了)。靜態伸展時，通過維持同樣姿勢一段時間 (約15-60秒不等，重覆數次)，來放鬆一塊肌肉或一組肌肉 (及附近的軟組織，如肌腱、韌帶)。

研究中，主要的好處是可以提升活動範圍 (ROM, range of motion)

※ 動態伸展 (Dynamic Stretching)

動態伸展，顧名思義，就是用一組動作，去讓目標肌群活動，以提升局部的血液供給，刺激神經肌肉連結，而達到熱身的目的。

為什麼動態伸展會越來越紅呢？其實和一些研究結果有關：

一開始，1980 年代的研究發現，運動前的靜態伸展會降低肌肉力量。後來就很多相關的研究報告指出：會造成跑步時的短跑時間減少、籃球運動員跳躍高度降低、足球運動員敏捷性降低以及精英男女運動員的力量產生減少等方面。

但是，靜態伸展並不會有長期的危害，這些肌肉力量下降也只是暫時性的；所以，我覺得拿來當運動後的收操動作是沒什麼問題的。而且，研究也指出，活動前靜態伸展的每個動作控制在45秒以內，就可以大大減少負面影響。

當然，有人說靜態的不好，就會有學者開始研究動態伸展的好處了；研究中指出，可以有效提高活動範圍、最大肌肉力量、短跑和垂直跳躍表現。另外，也有提到可以避免運動傷害。

〖小結〗

我個人建議如果是要去跟人家輸贏的時候，運動前的熱身以動態伸展為主，如果安插靜態伸展的動作，也不要單一肌群超過45秒；運動後則兩者都可以做，甚至明顯的肌肉緊繃的區域，還可以用泡棉滾筒去加強放鬆的效果。

After I posted on my leave plans on Sunday, a few of you asked what was on my reading list, so I am sharing some books I have read / am reading / or hope to read. Three of the books are available from the National Library Singapore. Do check out the NLB app (iOS: https://go.gov.sg/moiqhc | Android: https://go.gov.sg/hu17bc). It is a marvellous resource, and you will definitely be able to discover many books to suit your interests.

[ Nuclear Folly, a History of the Cuban Missile Crisis
by Serhii Plokhy ]
The Cuban Missile Crisis in 1962 brought the world to the brink of nuclear war. I had read "13 Days", the short memoir by Robert Kennedy about it as a teenager, and later Graham Allison's "Essence of Decision", a seminal study using the Crisis to analyse decision making from different perspectives. Both were mainly based on US records. Plokhy's book draws on Soviet archives, to present events from both the US and Soviet points of view. Many mistakes were made on both sides. The saving grace was that both President John Kennedy and General Secretary Nikita Khrushchev desperately wanted to avoid a nuclear war. But even then the two sides avoided a nuclear exchange only by a hair’s breadth, and only by chance, because events once set in motion were no longer entirely within the two leaders' control. A gripping read.

[ The Bilingual Brain, and what it tells us about the science of language
by Albert Costa ]
Having learnt several languages myself, and grappled with our bilingualism policy in schools, this book was a natural choice. I am still reading it. Did you know that a newborn infant already recognises and prefers the language (or languages) which their mother spoke while they were in her womb, and within hours of birth can also distinguish between two different languages that they have never heard before? Infants pick up a language (or two) naturally in their first years, but learning a second or third language later in life is much harder. This book explains why.

[ Capturing Light, the Heart of Photography
by Michael Freeman ]
A book about the different sorts of light, how they influence the photo you take, and how to use them to create the effect and mood that you want. Photographers know about the golden hour and blue hour, hard light and soft light, direct and indirect lighting, front and back lighting, haze, mist and fog, and so many more variations. The book includes lots of the author’s photos illustrating his points, taken over many years. Hope to pick up something from reading it. But the key in photography (as in so many other skills) is to practise and practise, if you want to improve.

[ Bettering Humanomics, A New, and Old, Approach to Economic Science
by Deidre Nansen McCloskey ]
The author, a distinguished economist, argues that economics is not just about incentives and institutions, mathematical models and observed behaviour. It should take a broader, more humanistic approach, paying attention to ethics and values, “what people believe, and the stories they tell one another”, as one reviewer put it. Certainly in government we must think about these broader factors all the time, while making sure we get the economics right. Not just in trade and industry or finance, but also in national development, education, health, manpower, sustainability and the environment, social and family development, and so much of public policy. I haven't read this book yet, but saw an enthusiastic book review, and look forward to reading the book itself.

Happy reading! – LHL

A short stop motion film, I use Prime from Transformers VS Zaku from Gundam story, see what they can do when they meet with each other, this video took me around 15 days of production and around 2000 pictures, hope you guys like it, thanks a lot :D

最近完成的一部短片, 用變型金鋼裡的柯博文對上鋼彈裡的薩克,
整部影片花了約15天共2000多張照片組合而成, 希望大家會喜歡, 感謝!
