Types of Muscle Contraction
BTEC BTECFIRST FIRSTIN INSPORT SPORT
When a muscle contracts, it does so in 2 main ways… Isometric Contraction or Isotonic Contraction.
1. Isometric Contraction
The muscle stays the same length as it works.
As a result there is no movement. The muscles in the back are a good example - the trapezius works in this way when maintaining our posture.
The hand push is another good example of isometric contraction.
