					DIFFERENT WAYS THAT MUSCLES
         CONTRACT
Muscles cannot “push” they can only “pull”. This
is called a MUSCLE CONTRACTION.

There are a number of different ways that a
muscle can contract:

1. ISOTONIC CONTRACTIONS
2.ISOMETRIC CONTRACTIONS
3. ISOKINETIC CONTRACTIONS
ISOTONIC CONTRACTION-

When the muscle both contracts and works
over a range of movement.
ISOMETRIC CONTRACTION-

When the muscle contracts but stays in a
fixed position, neither shortening or
lengthening.
ISOKINETIC CONTRACTION –

When your muscle contracts at constant
speed. For this you need specialist machinery.
