Types Of Muscular Contraction

Question 1

Types of muscular contraction

Answer 1

• isotonic eccentric
• isotonic concentric
  -isokinetic
• isometric

Question 2

Isotonic concentric contraction

Answer 2

-muscle length shortens during contraction
- working upwards against gravity
- most common

Question 3

E.g of isotonic concentric

Answer 3

Quadriceps in up phase of a squat

Question 4

Isotonic eccentric contraction

Answer 4

• muscle length increases whilst the force is being developed
  -lowering down with gravity

Question 5

Isotonic eccentric contraction e.g

Answer 5

Quadriceps in down phase of squat

Question 6

Isometric contraction

Answer 6

-Force is developed but there is no change in the length of the muscle
-Produces the most amount of force-> tires easily

Question 7

Isometric contraction e.g

Answer 7

Prone hold, rock climbing, gripping weights, holding a bat

Question 8

Isokinetic contraction

Answer 8

Muscle length changes and the force created by the muscle is maximal through the whole range of motion

Question 9

Isokinetic contraction e.g

Answer 9

Special isokinetic machines e.g isokinetic leg press or hamstring curl
