最強壯的肌肉是哪塊？
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.
是肱二頭肌、股四頭肌、還是臀大肌？如果告訴你這些都不是，估計你會很吃驚。給“強壯”的定義不同，答案也不同。今天我們就對此來探祕。
Ability To Exert Force
發力能力
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.
如果按發力大小來判斷，人身上最強壯的肌肉應該是咬肌。咬肌是臉上最厚的一塊肌肉，長在下巴後方。咬肌主要負責咀嚼時下巴咬合作用。
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.
咬肌是能發出最大力量的單獨肌肉。它的力量主要來源於高密度的肌纖維。咬肌能使門齒咬合時發出55磅的力， 臼齒則能發出200磅的力。
Which Muscle Does The Most Work?
幹活最多的肌肉是哪塊？
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“幹活最多”的標準來衡量肌肉強壯與否，那麼答案要數心臟了。人體心臟一直不停的做功，直到生命結束，所以心肌是“幹活最多”的肌肉。
What's The Largest Muscle?
最大的肌肉是哪塊？
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.
人體最大的一塊肌肉是臀大肌。臀大肌長在臀部，所以它的尺寸與人體日常活動息息相關。它的主要作用是支持人體直立。讓身體保持平衡。同時，在你行走或跑步時，它也能平衡重力。
