Question 8

Question 13

Concentric Contraction

Answer 13

Type of contraction where the ends of the muscle come closer together; muscle shortens when working

Question 14

Eccentric Contraction

Answer 14

Type of contraction where the ends of the muscle move farther apart; muscle lenthens when working

Question 15

Isometric Contraction

Answer 15

Type of contraction where muscle is working but doesn’t move position; muscle stays same length when working
