When a muscle is lengthening, it is going through a(n) ____ contraction. Example:lowering the weight in the bench press or squat
|
|
Eccentric

|
|
Concentric
|
|
|
Static
|

None of the above

Explanation:
Detailed explanation-1: -Eccentric contraction occurs when the force of contraction is less than the force of resistance. In other words, the force of resistance is greater than that of contraction, resulting in muscle lengthening and an increased distance between muscle origin and insertion.
Detailed explanation-2: -For example, when you lift a barbell, you are using concentric contractions; as you lower it, eccentric contractions are at play. Movements that employ eccentric contractions include walking down stairs, running downhill, lowering weights, and the downward motion of squats, push-ups or pull-ups.
