鍛鍊前的增補物真的有幫助嗎
Do Pre-Workout Supplements Actually Help?
鍛鍊前的增補物真的有幫助嗎?Pre-workout supplements make big promises to boost your performance, and with those promises come high price tags. You supposedly get a burst of energy, fatigue less easily, and increase blood flow, all to help you get more out of your workout. The thing is, these supplements are really just powerful stimulants.
鍛鍊前的增補物承諾會提高你的鍛鍊效果，伴隨這些承諾的是高額的標價。食用後，你應該能爆發能量，不會那麼容易疲勞，會增加血液流動，這些都會幫助你的鍛鍊。事情是，你吃的這些增補物真的只是有力的刺激劑。Pre-workout supplements are pretty popular, and you can find them from pretty much any company that also sells protein powders. Optimum Nutrition, MusclePharm, and Cellucor are just a few of the major players. They typically come in powdered form, are meant to be mixed with water, and taste like a flavored sports drink—which makes sense because they’re loaded with artificial sweeteners, coloring agents, and other ingredients that we’ll get to shortly.
鍛鍊前的這些增補物特別流行，你可以在幾乎所有售賣蛋白粉的公司裏找到這些增補物。最佳營養，肌醫藥和塞爾樂只是售賣這些增補物的一小部分公司。通常，它們都是粉狀的，應該與水混合使用，嚐起來就像加味運動飲料------這是有道理的，因爲它們含有人工甜料，着色劑以及下面我們很快將要講到的其它配料。
The Difference Between Various Kinds of Protein Supplements
不同種類蛋白補充物的區別They’re called protein supplements for a reason: you only need them if your current intake needs a boost.
它們都被叫做蛋白補充物是有原因的：只有當你現在攝入的東西需要推動時，纔會需要它們。Within 20-30 minutes of drinking one, you start to feel something, like it’s “kicked in,” and you’re ready for your workout. It’s a blessing, but also a curse.
喝了一杯之後，20-30分鐘內，你就會感覺到一些東西，就好像它在踢你，這就說明你已經準備好要去鍛鍊了。這是福佑，而不是詛咒。Most pre-workout supplements contain caffeine. And lots of it.
大多數鍛鍊前的補充物含有咖啡因，而且是大量的咖啡因。Caffeine is commonly used by athletes, especially those in endurance sports, to improve their exercise performance. It helps you focus more and feel less fatigue—exactly the claims the supplement labels make! So, in reality, when you feel like you’re ready to take on the entire weight room, you can thank the caffeine for that, not the supplement.
運動員通常都會使用咖啡因，尤其是考驗耐力運動的運動員，以提升他們的運動效能。咖啡因能幫助你更加專注，不那麼疲勞-------這就跟增補物標籤上說的一模一樣！所以，現實中，當你感覺你準備好開始健身房的所有項目時，你可以想這是咖啡因的作用，而不是補充物的作用。The pre-workouts I’ve tried from Optimum Nutrition, JYM, and Kaged Muscle contain between 175 milligrams (Optimum Nutrition) and 300 milligrams of caffeine per serving (Kaged Muscle). For real-world context, a single can of Red Bull has 80 milligrams of caffeine and a cup of coffee is close to 100 milligrams.
我從最佳營養，JYM和Kaged Muscle這些品牌中所嘗試的鍛鍊前增補物中，(最佳營養)每份含有175毫克咖啡因，（Kaged Muscle）每份含有300毫克咖啡因。在現實情況下，一瓶紅牛含有80毫克咖啡因，一杯咖啡中所含的咖啡因接近100毫克。
