What is isometric resistance?

What is an example of an isometric contraction?

Isometric contraction occurs when muscle length remains relatively constant as tension is produced. For example, during a biceps curl, holding the dumbbell in a constant/static position rather than actively raising or lowering it is an example of isometric contraction.

What are the 2 types of isotonic contractions?

Isotonic contractions – these occur when a muscle contracts and changes length and there are two types:

  • Isotonic concentric contraction – this involves the muscle shortening.
  • Isotonic eccentric contraction – this involves the muscle lengthening whilst it is under tension.
