Foam roller is just a colourful cylinder made of foam, which can be found in almost all fitness clubs or sports shops nowadays. It is created to relax fascia on your own. Rolling belongs to the SMR method – self myofascoal release. The popularity of foam rollers has made the SMR method available not only for physiotherapists and trainers, but also for any other people.
To be honest, SMR is the name of doing massage on your own, releasing tension and relaxing the trigger points. You can do it with your own hands, foam rollers, balls (tennis balls or specially designed lacrosse balls).
To make it simple, it's all about making pressure on particular points on the body in order to remove pain, achieve flexibility and the proper work of muscles.
In other words, there are Golgi tendon organs in fascia, which are sensitive to the changes in muscle tension. Stimulating them from outside (by rolling) causes the decrease of intramuscular tension and their relaxation. Moreover, rolling causes breaking the clumped muscle fibres. Those which occur inside fascia are the trigger points. Our aim is to find them and release.
They are sometimes easy to find, because they occur in the place of pain. However, it sometimes happens that the pain we feel is the result of radiating from another place of tension.
Rolling may be painful and it is definitely not the nicest activity. But remember, that pain should be bearable and you should feel better after rolling.
Why should we do something that causes pain? Isn't stretching enough?
Stretching is not enough. It's impossible to remove the trigger points during stretching and you don't relax your muscles then. Stretching, in a situation when you have painful trigger points, may be adverse. At such moment, it may contribute to extending one part of the muscle more than the other, which is why the intrafascial relaxation is not equal and you may overload some part of the muscle.
It's good to do the rolling, because releasing trigger points allows bringing back appropriate movement patterns and makes it possible to move without pain, which leads to bigger efficiency.
If you are able to to the movement properly without pain, your work is more efficient.
It is visible especially while doing squats. Tight fascia makes it impossible to do proper deep squat.
Working on releasing trigger points improves the technique of this exercise.
Rolling also helps to bring back the proper blood flow. By improving it, you will be able to provide nutrients to the tired muscles after workout. You will speed up the recovery time and you will make the relaxing time more valuable, therefore, you will gain power for further workouts.
