Question 5

Force is produced, muscle tension is developed, and movement occurs through a given range of motion. “constant tension”

Answer 5

Isotonic

Question 6

3 muscle actions

Answer 6

Concentric, isometric, and eccentric

Question 7

moving in the same direction as the resistance. Decelerates. Reduced force

Answer 7

Eccentric

Question 8

Moving in the opposite direction of force. Accelerates, Produces force

Answer 8

Concentric

Question 9

No movement with or against resistance. Dynamically stabilizes force.

Answer 9

Isometric

Question 10

The speed of mvmnt is fixed and resistance varies with the force exerted. Requires special equipment.

Answer 10

Isokinetic

Question 11

Tension while shortening or accelerating

Answer 11

Concentric

Question 12

Tension while lengthening or deceleration

Answer 12

Eccentric

Question 13

Muscle groups moving together to produce a joint movement

Answer 13

Force couple

Question 14

resting length of a muscle and the tension the muscle can produce at resting length

Answer 14

Length tension relationship

Question 15

Movement of bones around joints

Answer 15

rotary motion

Question 16

Force that produces rotation

Answer 16

Torque

Question 17

Difference between external and internal feedback

Answer 17

Internal: uses sensory info for feedback
External: provided by an outside source

Question 18

Muscles ability to produce tension @ differing shortening velocities

Answer 18

Force velocity curve
Concentric = decreases force production
eccentric= increases “ “

Question 19

Misaligned joints Like tight quads preventing the hamstrings from using appropriate force is an examples of

Answer 19

altered length relationship
