While treating patients in our clinic, we often times need
to help them increase their muscle flexibility in order to overcome pain from
an injury. Back when I was in school
and taking part in clinical experiences, I was taught to stretch patients or
teach them stretching exercises using “static” techniques. This means I would or the patient
would hold a muscle stretch for a period of time, typically 20 to 30 seconds,
before relaxing. This was repeated
a few times in order to gain muscle length and flexibility.
Dynamic stretching exercises are different than static stretches because they involved continuous movement throughout the exercise in order to gain muscle flexibility (hence, the use of the word dynamic to describe them). Occasionally, we still use static
stretching techniques in our clinic, but we have found “dynamic” stretching
exercises to be more effective for patients for reasons listed below:
1)
Dynamic stretching exercises are more effective
in “warming” up a muscle and promoting blood flow to the region. This allows the muscle to feel more
“loose” as compared to when stretching the same muscle statically. This in turn prevents injury to “cold”
muscles that have not been stretched prior to treatment or exercise, as can
happen when people try to stretch using a static stretch technique.
For example: Try stretching your hamstrings
statically by standing on one leg and placing the stretch leg on a chair seat
while leaning forward. The muscle
feels tight, even after you have stretched for 20 – 30 seconds. Now try the Front to Back Leg Swings exercise shown in
this video link for 20 to 30 repetitions.
What felt better as a stretch?
Which stretch was more effective for increasing flexibility? Which was easier to do? My bet is you chose the dynamic
stretch.
2)
Dynamic stretching allows for increased
flexibility for more than one muscle group. Take the hamstring sample again. With a static stretch, you only feel the hamstring
stretching. With the dynamic Front to Back Leg Swings stretch, you involve movement of more than just the hamstring muscle. You also involve the gluteal muscles,
low back muscles, along with the hip flexors and quads when you move your leg
backwards during the exercise.
Because our movement patterns for any activity we do typically involve
more than one muscle group, the dynamic stretch is more functional and
effective in respect to our movement patterns.
3)
Dynamic stretches are generally more comfortable
to do than static stretches because the muscle is not held in a stretch
position for a long period of time.
Think about when you try stretching a muscle to far – it can hurt. That is why even a regular static
stretch is not the most comfortable thing for people, and typically why we tend
to avoid doing them. With a
dynamic stretch, the muscle is lengthened only for a very short period of time,
and then released. This allows the
muscle to more effectively release, helping you to gain more movement range with
each repetition.
4)
Dynamic stretching exercises are also effective
in promoting strength and stability, two additional key components to proper
muscle function. Take
the leg whip stretch again. While
stretching the motion leg, the muscles in the opposite leg are required to be
active in order to maintain balance.
Another example is the Windmills stretch shown here – in this exercise,
the hamstring and low back muscles are not only being stretched, they are being
strengthened eccentrically, meaning the muscle is gaining a greater ability to
lengthen while decelerating movement against gravity. For someone who carries a lot of upper body weight, this type
of strength is extremely important in preventing injury. It is also another example why dynamic
stretches are more functional than static stretches.
5)
Overall as shown above, dynamic stretching
exercises give you more bang for your buck in usually less time. We have designed dynamic warm-up
routines that improve total body flexibility in 10 minutes versus doing 4 or 5
static stretches for only 4 – 5 muscles over the same period of time. Because dynamic exercises also promote
blood flow, energy use, and muscle strengthening, you also feel like you have
done a bit of a workout after performing them.
I have included additional links to YouTube videos
demonstrating some dynamic exercises we teach at our All-Access Fitness Academy
and in our clinic below. If you are
interested in learning a dynamic stretching routine, let us know and we’ll
discuss designing a program that is right for you. Exercise Samples: Toy Soldiers; Running Butt Kicks; High Knee Walks.
