trainers and Singapore fitness bootcamp owners like myself regarding power
plate training or vibration plate training courses.
I am always trying to improve my knowledge so that I can help clients
better and get them results more quickly...but we also should be picky
about the kinds of methods we use.
"Power plate" is a cool name, but for a machine costing about 10,000 SGD
per piece it better do more than sound cool. We could set up a decent
small gym or home gym for the price of that machine alone!
What is a powerplate? It is a surface about 1m by 1m in size that
vibrates. That is it.
What does it claim to do? It claims to improve your blood circulation,
flexibility, and increase bone and muscle strength.
Possible... yes!
But I believe only for a VERY untrained or elderly patient and only for a
limited time till be the body gets used to it.
The claim about boosting flexibility does hold some interest for me. The
reason for this is that fast vibrations are known to "turn off" what are
known as spindle cells in your muscles. These Spindle cells are in all of
our muscles and they report to our body changes in the lengths of our
muscles.
So if we turn them off using vibrations from a power plate, you don't
"tighten up" when you try to stretch, so you can improve flexibility. The
usual "stretch reflex" is turned off. (you know, the one where you spasm
if you stretch too far beyond your current flexibility)
However... if you do this too much, you might "turn off" the spindle cells
too much and then your body will lose coordination because it has no clue
how long the muscles are and how fast their length is changing.
In addition this stretch reflex has a role in producing speed and power,
and this may decrease as well.
Finally, the stretch reflex is an injury prevention mechanism in your
muscles so if you turn it off long term its bad news for preventing muscle
tears/pulls.
Also, any good flexibility program can get you to improve flexibility and
range of motion without these side effects.
In conclusion, I don't have an issue so much with the power plate or
vibration platform. I am just concerned that it is not good value and that
its claims are overblown. For the price, get yourself a good set of weight
plates, bar, power rack and dumbells!
NOTE: Most countries have laws against how many hours per day you can
operate heavy machinery like jackhammers. This is because constant
vibration is not a good idea for your body especially internal organs.
Please consider this when deciding if a vibration platform is the kind of
device you want to choose to train on.
