Stretching
Types
of Stretching
In general, any movement that requires moving a body part to the
point at which there
is an increase in the movement of a joint can be called a
stretching exercise. Stretching
can be done either actively or passively. Active stretching occurs
when the person doing
the stretch is the one holding the body part in the stretched
position. Passive stretching
occurs when someone else moves the person to the stretch position
and then holds the
person in the position for a set time. The four major types of
stretches are static, proprioceptive
neuromuscular facilitation (PNF), ballistic, and dynamic. The
static stretch is used
most often. In static stretching, one stretches a particular
muscle or group of muscles by
slowly moving the body part into position and then holding the
stretch for a set time.
Since the static stretch begins with a relaxed muscle and then
applies the stretch slowly,
static stretching does not activate the stretch reflex (the knee
jerk seen when the tendon
is tapped with a mallet). Activation of the stretch reflex causes
the stretched muscle to
contract instead of elongate. This contraction of the muscle is
directly opposite of the intent
of the exercise. PNF stretching refers to a stretching technique
in which a fully contracted
muscle is stretched by moving a limb through the joint’s range of
motion. After moving
through the complete range of motion, the muscle is relaxed and
rested before resuming
the procedure. The combination of muscle contraction and
stretching serves to relax the
muscles used to maintain muscle tone. This relaxation allows for
increased flexibility by
“quieting” the internal forces in both the muscles that assist and
the ones that oppose the
movement of the joint in the desired direction. Ballistic
stretching uses muscle contractions
to force muscle elongation through bobbing movements where there
is no pause at any
point in the movement. Although the bobbing movement quickly
elongates the muscle
with each repetition, the bobbing also activates the stretch
reflex (or knee jerk) response.
Since the stretch reflex stimulates the muscle groups to contract
after the stretch is finished,
ballistic stretching is usually discouraged. Dynamic stretching
refers to the stretching that
occurs while performing sport-specific movements. Dynamic
stretching is similar to ballistic
Stretching in that both use fast body movements to cause muscle
stretch, but dynamic
stretching does not employ bouncing or bobbing. Additionally,
dynamic stretching uses
only the muscle actions specific to a sport. Practically speaking,
dynamic stretching is similar
to performing a sport-specific warm-up (that is, performing the
movements required for
the activity but at a lower intensity).
Benefits
of Stretching
The following are several chronic training benefits gained from
using a regular stretching
program:
• Improved flexibility,
stamina (muscular endurance), and muscular strength. The degree
of benefit depends on how much stress is put on the muscle. Medium
or heavy
stretches are recommended. You can do this by building up to doing
long stretches
of high intensity (see the next section for a detailed explanation
of light, medium,
and heavy stretching).
• Reduced muscle soreness,
aches, and pains. Use only very light stretches if muscle
soreness prevails.
• Improved flexibility with
the use of static or PNF stretches. Medium or heavy stretches
are recommended.
• Good muscular and joint
mobility.
• More efficient muscular
movements and fluidity of motion.

• Greater ability to exert
maximum force through a wider range of motion.
• Prevention of some lower
back problems.
• Improved appearance and
self-image.
• Improved body alignment and
posture.
• Better warm-up and cool-down
in an exercise session.
General
Recommendations
• Try to include all the major muscle groups in any stretching
program.
• Do at least two different stretches for each joint movement.
• Before any physical activity, use light stretches as part of the
warm-up.
• After an exercise routine, cool down with medium-intensity
stretches.
• If muscles are sore after exercising, use only light stretches two
or three times with a
5-
to 10-second hold for each stretch performed.
• If muscle soreness persists for several days, continue using light
stretches two or three
times
with a 5- to 10-second hold for each stretch performed.
• The majority of the stretches should be static.
Stretching
Programs
The
following programs can be prescribed for anyone who is interested in improving
flexibility,
strength,
and strength endurance. To make changes to any of these areas, you need
to
be involved in a regular stretching program, preferably as a daily routine or
as close to
that
as possible. Changes will not come in a day or two but rather after a dedicated
effort
of
several weeks. You can incorporate these programs with or without any other
kind of
exercise
routine. According to the latest research, heavy stretching, even without any
other
exercise
activity, can bring about changes in flexibility, strength, and muscular
endurance.
As
in any other exercise program, progression is an integral part of a successful
stretching
program.
The stretching progression should be gradual, going from a lighter load with
less
time spent on each stretch to a heavier load with more time spent on each
stretch. For
the
programs outlined in this introduction, you should begin with the initial
program, or
level
I, and then progress through to level V. However, you may customize this
program
according
to your current level of experience and flexibility. Generally, working through
each
level
at the recommended speed will result in meaningful and consistent workouts.
After
such
workouts, you will find improved flexibility in the muscles you worked as well
as the
satisfaction
of having done something beneficial.
Intensity
is always a critical factor when you want changes and improvements to come
from
an exercise program. In a stretching routine, intensity is controlled by the
amount of
pain
associated with the stretch. Using a pain scale from 0 to 10, initial pain is
light (scale of
1 to
3) and usually dissipates as the time of stretching is extended. Light
stretching occurs
when
you stretch a particular muscle group only to a point where you feel the
stretch with
an
associated light pain. Moderate stretching (scale of 4 to 6) occurs when you
start to feel
increased,
or “medium,” pain in the muscle you’re stretching. In heavy stretching (scale
of
7 to
10), you will initially experience a moderate to heavy pain at the start of the
stretch,
but
this pain slowly dissipates as stretching continues. Research studies have
shown that
heavier
stretches rather than lighter stretches provide greater improvements in
flexibility
and
strength. Thus, you are the key to your own success, and how well you are able
to
monitor
stretch intensity and tolerate the pain level determines how quick and large
the
improvements
will be.
Because
of the complexity of muscle attachments, many stretching exercises
simultaneously
affect
a variety of muscle groups in the body and stretch the muscle groups around
multiple
joints. Thus, a small change in body position can change the nature of a
stretch on
any
particular muscle. To get the maximal stretching benefit in any muscle, it is
helpful to
know
joint movements that each muscle can do. Putting the joint through the full
range of
each
motion allows for maximal stretching.
You
can customize the exercises in this book, which will allow for numerous stretch
combinations.
Also, this book illustrates only a portion of the available stretches. You are
encouraged
to experiment with these stretches by following the explanations provided.
Information
is also provided to enable you to explore a variety of positions in order to
stretch
the
muscle by slightly altering the angles and directions of the various body
positions. Thus,
you
can adapt the stretching exercises to fit your individual needs and desires.
For example,
if
you have soreness in only one of the muscles or just a part of the muscle, you
can adapt
each
exercise to stretch that particular muscle. If the explained stretch or
particular body
position
does not stretch a particular muscle as much as you want it to, then experiment
by
slightly altering the position. Keep making alterations in the position until
you reach the
desired
level of stretch (using a pain scale rating).
In
the programs that appear in the following section, specific instructions are
given relating
to
the time to hold the stretch and time to rest between each stretch, as well as
the number
of
repetitions you should do. You should follow these instructions in order to get
the benefits
described.
For example, if the instructions indicate that you should hold a stretch
position for
10
seconds, time (or count out) the stretch to ensure that you hold it for the
recommended
time.
Also, you should incorporate only two to four heavier stretching days in each
week
and
have a lighter stretching day in between each of the heavier stretching days.
Finally,
for any stretch involving sitting or lying down, you should do the stretch with
a
cushion
underneath you, such as a carpet or athletic mat. Cushioning makes the
exercises
more
comfortable to perform. However, the cushioning should be firm. Too soft of a
cushion
will
reduce the effectiveness of the stretches.
