Flexibility
Training
Flexibility
training involves performing a series of exercises that help
maximize range of motion and muscle stability. The benefits are
improved blood flow in the muscles and lower risk of
injury.
There are three
basic types of stretching exercises that help accomplish these
goals: static, dynamic and Isometric/PNF.
Static
stretches are the most traditional type, encompassing the more
or less standard 'pull to maximum end point, hold for five or
ten seconds, then release' group of
exercises.
Static
stretches should form part of every 10 minute warm-up routine.
Every major muscle group should be given a gentle pull, hold
and relax. This helps improve the circulation and readies the
muscles for more vigorous activity, while decreasing the risk
of tears or tendon stretching.
Dynamic or
ballistic stretches are more controversial, since they involve
stretch with added momentum or even using weights. They are
potentially harmful and that risk-factor is one of the major
elements behind the controversy. At minimum, you should seek
out a knowledgeable trainer before engaging in this form of
flexibility training.
As one example,
rest one knee on a ball and slowly rotate the ball away from
the body, giving a very moderate bounce at the maximum point.
Lunges, performed by moving one foot ahead, kneeling slightly
with the back straight and bouncing gently, would be
another.
PNF
(Proprioceptive Neuromuscular Facilitation) involves a
combination of passive and isometric exercise. Apart from
having a fancy technical name and associated acronym, PNF
actually has several useful features that should motivate
individuals to investigate its value.
Performed
properly, under the guidance of an experienced fitness
professional or devoted amateur, PNF can maximize range of
movement and best prepare the body for more strenuous
exercise.
Several
exercises involve using a partner. The muscle group you want to
work is stretched under tension, then contracted for several
seconds, and your partner applies resistance to inhibit
movement.
For example,
stretch your arms out and slowly move them behind you, then
contract the biceps, triceps and shoulders. Have the partner
gently pull your hands together a little past the 180 degree
mark as you attempt to pull your arms back to 180
degrees.
As another
example, lie on your back on a comfortable surface. Raise one
leg vertically and have your partner grab your foot. Your
partner then presses the foot gently backward until you feel
tension on the hamstring (the muscle on the rear of your
thigh). You then contract the muscles as you attempt to move
your leg back down, with your partner resisting the
movement.
These examples
are to serve only to give a general idea of the exercises. PNF
exercises should only be attempted after you have received
proper, hands-on training. Done incorrectly they can lead to
muscle sprain or joint damage.
Whatever your
workout routine, be sure to precede it by good flexibility
exercises. That will maximize your performance during the more
strenuous part of the total workout.
