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

Respuesta :

Answer:

D. A positive contraction

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.
