Lesson 12.1 Vocabulary

Question 1

active stretch

Answer 1

stretch caused by contraction of your own antagonist muscles

Question 2

antagonist

Answer 2

muscle or muscle group having the opposite function of another muscle or muscle group

Question 3

ballistic stretch

Answer 3

series of gentle bouncing or bobbing motions that are not held for a long time

Question 4

CRAC

Answer 4

contract-relax-antagonist-contract; a type of PNF stretch that first requires the muscle or muscles to contract and then relax before being stretched by the contraction of the opposing muscle or muscles

Question 5

dynamic movement exercise

Answer 5

exercise such as jumping, skipping, and calisthenics that is often used in a warm-up for activities requiring strength, power, and speed and that moves the joints beyond normal resting ROM and causes the muscles and tendons to stretch; the stretch caused by dynamic movement exercise is followed by a contraction of the stretched muscle

Question 6

dynamic stretching

Answer 6

slow movement exercises designed to lengthen the muscles

Question 7

hypermobility

Answer 7

unusually large range of motion in the joints; sometimes referred to as double-jointedness

Question 8

muscle-tendon unit (MTU)

Answer 8

skeletal muscles and the tendons that attach them to bones

Question 9

passive stretch

Answer 9

stretch requiring an assist from an external source (gravity, a partner, or some other source)

Question 10

PNF stretch

Answer 10

flexibility exercise using proprioceptive neuromuscular facilitation; a variation of static stretching that involves contracting a muscle before stretching it

Question 11

range of motion (ROM)

Answer 11

the amount of movement in a specific joint that is considered to be healthy (neither too much nor too little)

Question 12

range-of-motion (ROM) exercise

Answer 12

exercise that requires a joint to move through a full range of motion by using either your own muscles or the assistance of a partner or therapist

Question 13

static stretch

Answer 13

stretch performed slowly as far as you can without pain, until you feel a sense of pulling or tension
