What are the types of resistance exercises and name an example.

Question 1

Isotonic

Answer 1

Isotonic (now known as Dynamic exercise) – is carried out against a constant or variable load as a muscle lengthens or shortens through the available range of motion (ex: free weights)
-contraction type is concentric and eccentric

Question 2

Isokinetic

Answer 2

is a form of dynamic exercise in which the velocity of muscle shortening or lengthening is controlled by a rate limiting device the controls the speed of movt (ex:Cybex)

Question 3

Isometric

Answer 3

static form of exercise that occurs when a muscle contracts without an appreciable change in the length of the muscle

  - should be held for at least 6 seconds
  - since there is no joint movement, strength is increased only at the position being held do you need to do multiple angles to increase a broad range of strength in the muscle
  - Low intensity isometric = muscle setting – gentle static muscle contractions used to maintain mobility between muscle fibers and decrease spasm.
