Stretching
is a frequently overlooked component of a conditioning program.
Flexibility exercises are designed to elongate the soft tissue of the
body. Stretching
has several benefits, including:
injury prevention, enhanced performance, improved joint range of motion,
and decreased muscle soreness after strenuous exercise. Flexibility
exercises cause the muscle, its connective tissue and frame work to elongate.
The muscle tissue lengthens more than the structural components.
The structural components do not need to be elongated as this may
compromise joint integrity.
Flexibility exercises should merely increase the plasticity of these
structures while lengthening the muscle tissue itself. Stretching
should always be performed slowly with control.
If a stretch is instituted too rapidly the muscles protective mechanism
kicks in (stretch reflex) and the muscle tissue actually tightens.
This is why ballistic movements are discouraged during stretching
exercises. There
are two (2) basic types of flexibility exercises.
Static Stretching is performed by passively placing the muscle in
a maximally lengthened position and holding it there for a sustained interval
(10 - 30 seconds). Proprioceptive
Neuromuscular Facilitation (PNF) is a technique using combinations of
alternating contractions and relaxations of agonist and antagonistic muscles.
A partner will assist the individual being stretched in resisting the
motions caused by muscle contraction.
To perform this technique, knowledge of the agonist and antagonist muscle
function is necessary. Prior
to stretching, a full-body warm-up should be performed.
This may include a light jog or bicycle ride, or any other low level
aerobic activity performed 5 - 10 minutes prior to stretching.
When perspiration begins to flow, the core temperature has been
sufficiently raised to facilitate Selecting
proper stretching techniques is very important.
Just as ballistic or bouncing during a stretch is counterproductive, some
stretches can cause damage.
The "Hurdler's Stretch," for example has been shown to cause
damage to the meniscal cartilage in the knee.
One must also know the athletes' "tight Spots" and be able to
design specific flexibility programs to target these areas.
