There haven't been any official research on this particular topic, but somehow I get this feeling that Kinesiology taping is much more popular between people in Latvia than it is in London.
In LV this method became viral few years ago when Taping finally became available for those who work in rehabilitation, but in sports medicine it was there for a long time.
Since I'm in London I haven't been able to make a discussion about Kinesiology taping(I keep in mind that maybe I haven't met right people yet:)) with anyone, because nobody knows about it, some have seen few colorful tapes used on athletes in Olympic games, but I feel it's not enough respect towards Kinesiology taping. It should be much more appreciated from Personal Trainers, and much more popular between those who train, because it definitely isn't just for athletes! To make it more clear what am I talking about I will try to explain.
Kinesiologiy Taping is method which uses elastic tape in order to support body's own healing process.
This method was already developed in the 1980s in Japan when researching and understanding all muscle functions and dysfunctions became so popular that a new method, that improves muscle function using outside assistance, was found.
Tape is modeled on the skin’s characteristics and it is able to transmit sensory information to the body. We also need to keep in mind it's ability to stretch longitudinally when placed on the skin. The tape lifts the epidermis after being applied and this 'lifting' increases space between the skin and the underlying connective tissues, vessels and muscles to improve mobility and aid lymphatic and venous movement. The 'lifting" also has an effect on reducing pain, decreasing susceptibility to microtrauma and improving muscle performance.
Therapeutic effect is more or less the same for all available colors, unless you dig deeper and use chromotherapy(color therapy). Application techniques are different and effects are different.
Kinesiology Taping Method is applied over muscles to reduce pain and inflammation(it could be your lower back, your ankle or that knee that is bothering you for weeks), relax overused tired muscles, and to support muscles in movement on a 24hr/day basis.
It is non-restrictive type of taping which allows for full range of motion. Some less popular, but not less effective application methods we can use treating hematoma, oedema and even scar tissues.
Now, knowing at least this little, you should be able to understand situations where you don't need to use medicine, suffer pain, but you could just ask for little bit of tape.
Of course it's not one and only method to treat muscles and surrounding tissues,you still need exercise, stretch and have some good nights sleep, but it is one pain free, non invasive approach your trainer could use to help you treat the situation or to help to prevent it! Do not hesitate to ask, maybe there is knowledge and just lack of advertisement :)
