鍛煉前的增補物真的有幫助嗎

　　錘煉前的補充物真的有贊助嗎?

　　錘煉前的補充物許諾會進步你的錘煉後果，隨同這些許諾的是高額的標價。食用後，你應當能暴發能量，不會那末輕易疲憊，會增長血液活動，這些都邑贊助你的錘煉。工作是，你吃的這些補充物真的只是有力的刺激劑。

　　錘煉前的這些補充物特殊風行，你可以在險些全部售賣卵白粉的公司裏找到這些補充物。絕佳養分，肌醫藥和塞爾樂只是售賣這些補充物的一小部門公司。平日，它們都是粉狀的，應當與水混雜應用，嘗起來就像加味活動飲料------這是有事理的，由於它們含有人工甜料，著色劑和下面咱們很快將要講到的別的配料。

　　分歧種類卵白彌補物的差別

　　它們都被叫做卵白彌補物是有緣故原由的：只有當你如今攝取的器械須要推進時，才會須要它們。

　　It’s Mostly the Caffeine That “Works”

　　Most pre-workout supplements contain caffeine. And lots of it.

　　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.

　　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.

　　Do Pre-Workout Supplements Actually Help?

　　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.

　　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.

　　The Difference Between Various Kinds of Protein Supplements

　　They’re called protein supplements for a reason: you only need them if your current intake needs a boost.

　　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.

　　喝了一杯以後，20-30分鐘內，你就會感到到一些器械，就似乎它在踢你，這就解釋你已預備好要去錘煉了。這是福佑，而不是咒罵。

　　大多半錘煉前的彌補物含有咖啡因，並且是大批的咖啡因。

　　活動員平日都邑應用咖啡因，特別是磨練耐力活動的活動員，以晉升他們的活動效能。咖啡因能贊助你加倍專註，不那末疲憊-------這就跟補充物標簽上說的千篇一律!以是，實際中，當你感到你預備好開端健身房的全部項目時，你可以想這是咖啡因的感化，而不是彌補物的感化。

　　我從絕佳養分，JYM和Kaged Muscle這些品牌中所試下的錘煉前補充物中，(絕佳養分)每份含有175毫克咖啡因，(Kaged Muscle)每份含有300毫克咖啡因。在實際情形下，一瓶紅牛含有80毫克咖啡因，一杯咖啡中所含的咖啡因靠近100毫克。
