The responses given are right on the mark. One thing to keep in mind is that if the intention of the stretch is to increase ROM about a joint a dynamic warm-up is essential in order to increase the temperature in the soft tissues (fascia) that will respond to the overload of the stretch. It’s also why, in general, it’s most effective if the stretch is held for at least 5-8 seconds.
As LaRue Cook said, dynamic stretching does incorporate a stretch, but it’s just movement (dynamic) based rather then the 15-30 seconds and hold (static)strech. Dynamic stretching is highly recommend before exercise, as it prepares the body for the exercise movements that will come. This does not mean that you do not perform static stretching at all, it’s just not recommended before exercise. In additon, dynamic stretching can also help with stability and balance as they are performed.
There are many types of Dynamic Stretch exercises, but examples include: Jumping Jacks, Seal Jack, Leg Swings, Arm Circles, Walking Lunge, Inch Worm, Frankenstein March, Knee Hug, Butt Kicks, & High knees.
Perhaps it’s me. I a bit confused about the question.
Are you referring to dynamic stretching or a warmup? Generally, one warms up and then stretches.
There are a host of stretches one can perform–myofascial release, static stretches, proprioceptive neuromuscular facilitation, active isolated stretches and dynamic and ballistic stretches.
It is important that you take the level of conditioning of your client into account to determine the type of stretch you will perform.
Hope this helps.
