11
Static
Ballistic
Concepts of Physical Fitness 12e
Static Stretching




12
Stretch slowly until tension
Hold stretch for 10 - 30 sec.
Relax the muscle
Increase stretch a bit more
(developmental stretch)
Concepts of Physical Fitness 12e
Stretch
Reflex
Maintaining
stretch for
10- 30 seconds
will allow the
stretch reflex
to subside and
permit gains.
Ballistic Stretching


14
Dynamic movement
Specificity of movement
