Question

Which of the following is an example of a concentric contraction?

Dance move

Injuring a non-dominant muscle

Bicep curl

Slowly putting a heavy object down

Answer 1

I would say C. Bicep Curl

A "bicep curl" is like an exercise that targets the bicep muscle (which is your upper arm that's between your shoulder and your elbow)

Answer 2

Bicep curl.

Step-by-step explanation:

Concentric contraction is a muscle activation that cause tension through as the muscle shortens, generating force to move objects like dumbbells. So, during bicep curl, this tension by muscle shortening is always present because of the position that weigh is being lift, being biceps the muscles involved. (see image attached).
