Most of us have always been encouraged to stretch and, in many cases, rightly so. Before we began our work out or physical activity we limbered ourselves up and tried to gain more flexibility. Which intuitively makes sense.
However, more recent research tells us that we can lose up to 20% of our power after stretching and so competitive athletes no longer stretch themselves before big events. This research led to very heated discussions that surely this would lead to injuries as we don’t prepare our muscles for the ensuing stimulation and strenuous tasks we are about to ask of them. Some people feel that with out their daily stretching routine they would not be able to function and only feel unwanted pain.
After years of experience at the muscle and movement company and reading many other articles and papers, I have personally cut back on static stretching and am very wary about advising people to stretch until I know for certain that it may help them. I have seen many injuries that have resulted from over stretching or from stretching a weakness beyond where it was able to go.
The body operates in a balance. Agonist to antagonist, front to back, left to right and there is only so much variance in these ratios that the body will allow until it begins to object, often using the only method it knows your brain will listen to, pain.
Chronic pain, or musculoskeletal imbalances is what we mostly deal with at the Muscle and Movement company. It is so important that tests are carried out to help determine to root cause of this pain and so the right course of action can be embarked upon. This is where in some cases stretching may not be the right answer.
For ease of understanding I will use the quads and hamstrings as an example. Whilst there are more muscles in each of these kinetic chains, this is merely to illustrate the point.
Mr X is able to extend his knees using his quads to a weight of 200kg. He can flex the knees using his hamstrings to a weight of 50kg. He complains of sore knees and tight hamstrings and notes a limited range of movement when he tries to touch his toes. Each morning the pain is worse, but as the day passes it begins to ease and stretching his hamstring helps a little, but it never lasts long. The pain was getting worse by the day and he hurt himself the previous day when he tried to kick a ball.
There is a ratio, a relationship of strength between quads and hamstrings. 60/40. Quads/hamstrings. You see from his strength abilities he is considerably out-with this ratio. Testing his hamstring strength only leads to cramp. We can determine he has a weakness in his hamstrings that are struggling to support his knees. The action of kicking the ball requires contraction from the quads which, in turn stretches the hamstrings. The lack of strength in the hamstrings was unable to cope with the stretch which resulted in the subsequent strain. Any further stretching to the hamstring is likely to tear the muscle further. Mr X needs to allow time for healing and work on building strength to the hamstring to make them more robust, thus allowing full function of the knees.
This is not to say that you should not perform stretches or avoid going to yoga, operating in a full range of motion not only strengthens the agonist you are using but will in turn stretch the antagonist to which it refers. This not only leads to an increase in strength but an increase in range of motion, whereby you now have the best of both worlds. Listen to your body when it nags at you and determine what it is trying to tell you. Look at your training plan and make sure your strength is distributed throughout your body where it should be.
Hypermobility sufferers should be very cautious when stretching. Strength imbalances can lead to an excessive range of motion that can lead to potentially nasty consequences. Careful consideration should be given to your body before you embark on a new stretching routine. If you are unsure, ask your gym instructor or muscle health professional who should be able to help guide you, or if you are at the EICA:Ratho, come and ask us, we are always happy to help.
