While running down a hill, the hamstrings decrease in length while producing tension. What type of contraction is performed?
2 answers:
Answer:
D. A positive contraction

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.
