What Is The Strongest Muscle In Your Body?
身体最强壮的肌肉是哪一块？
What is the strongest human muscle?
最强壮的肌肉是哪块？
Is it your biceps, quadriceps or could it be your gluteus maximus? You might be surprised to learn that it's none of the above. The question can be a tricky one to answer since it depends entirely on what your definition of"strongest”is. Today we’ll explore this little life mystery.
是肱二头肌、股四头肌、还是臀大肌？如果告诉你这些都不是，估计你会很吃惊。给“强壮”的定义不同，答案也不同。今天我们就对此来探秘。
Ability To Exert Force
发力能力
If by strongest you mean"ability to exert a force on an external object”, then a human's strongest muscle is his or her ‘masseter’ muscle. The masseter muscle is a thick muscle in the cheek and is located at the back of the jaw. It's responsible for opening and closing your jaw during chewing.
如果按发力大小来判断，人身上最强壮的肌肉应该是咬肌。咬肌是脸上最厚的一块肌肉，长在下巴后方。咬肌主要负责咀嚼时下巴咬合作用。
It is the muscle that can generate the largest externally measurable force attributable to the action of a specific, single muscle. Its strength is the result of incredibly densely packed muscle fibers combined with being attached to a short-armed lever. It can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (91 kilograms) on the molars.
咬肌是能发出最大力量的单独肌肉。它的力量主要来源于高密度的肌纤维。咬肌能使门齿咬合时发出55磅的力， 臼齿则能发出200磅的力。
Which Muscle Does The Most Work?
干活最多的肌肉是哪块？
Now if you take ‘strongest’ to mean ‘does the most work’, the heart lies claim to that. The heart does its work continuously over an entire lifetime without pause, and hence ‘outworks‘ every other muscle.
如果用“干活最多”的标准来衡量肌肉强壮与否，那么答案要数心脏了。人体心脏一直不停的做功，直到生命结束，所以心肌是“干活最多”的肌肉。
What's The Largest Muscle?
最大的肌肉是哪块？
The largest muscle in the human body is the gluteus maximus. The gluteus maximus is located in your buttocks and its size directly corresponds to the important role it has in your everyday life. It's main function is to keep your body erect and straight. Its function is to provide balance and a center of gravity while walking or running.
人体最大的一块肌肉是臀大肌。臀大肌长在臀部，所以它的尺寸与人体日常活动息息相关。它的主要作用是支持人体直立。让身体保持平衡。同时，在你行走或跑步时，它也能平衡重力。
