Question

While running down a hill, the hamstrings decrease in length while producing tension. What type of contraction is performed?

OA. An isometric contraction
OB. A negative contraction
OC.
A static contraction
OD. A positive contraction

Answer 1

D. A positive contraction

Step-by-step explanation:

Isometric contraction occurs when muscle length remains relatively constant as tension is produced. So that is not the right answer.

A concentric contraction is a type of muscle contraction in which the muscles shorten while generating force. It is also called positive contraction.
