The higher the intensity the better. Intensity means current (mA, or milliamps). Higher current penetrates deeper in the muscle tissue, thus recruiting more muscle fibers. Higher recruitment means helping more blood flowing in a larger portion of the muscle.
Because Active Recovery programs (like those in Globus and Compex machines) are made of twitches rather than sustained contractions, and twitches develop only about 1/3 to 1/4 of the force one develops with a sustained contraction, one doesn’t run the risk of overloading muscle fibers and the tendons, or to make them sore.
There are a couple of differences between the Globus and Compex Active Recovery, if anybody is interested.
Based on my experience, I do believe there is an “optimal” intensity for the recovery settings. While this optimal intensity is not low, it is not necessarily has high as you can handle. I’ve had variable results with different individuals - which I assume correlates with muscle fiber type.
In some cases, I have dialed down the intensity slightly and experienced better results. I would assume it is similar to a massage session, where too hard and deep a massage can have less optimal results. There is likely a point of diminishing returns. As with training, it is your job to determine “how much, how long, how frequently, etc.” based on your experience with various individuals and their tolerances.
Number Two,
I do not disagree with you: personal experience rules over theory. I’m inclined to think though, that if ESTI did not get any result, either the training was not stressing the body (i.e. didn’t need active recovery), or the Active Recovery program was too weak, and didn’t make a difference.
Correct, I did not need the program, was curious to see if how it felt during and after the treatment.
My athlete yesterday left feeling better, and today during a game felt tight and overall not well. Not sure if intensity was high enough, or too high??
There was a good amount of vibration of the muscles during treatment. Any idea how you can gauge intensity of treatment?
I think feedback from the athlete to gauge intensity can be useful.
And I am not sure how much time you spent doing stim with this athlete but don’t be so sure the tightness had anything to do with what you did or didn’t do.
You gotta try and keep records and see how it goes over time.
Think about using the stim on the glutes first ( active recovery) to supply blood flow for tight hams.
The Active Recovery program makes the muscles twitch at frequencies between 1 and 9 Hz. This means that the muscle pulsates from 1 to 9 times per second. However, you can do this in different fashions. At Globus we experimented with different ways of doing this, and found that people seemed to get a better recovery and in a shorter time with a specific variation on this theme. This was adopted as the standard program.
In a nutshell, the change from 1 to 9 Hz can be done in a cycle lasting a certain number of minutes. The cycle adopted by Globus lasts a fraction of a minute and is repeated over and over. The cycle adopted by Compex takes 25 minutes and is done only once. I have my own theory, why cycling active recovery in shorter cycles apparently produces better results. But I would be interested in the opinion of others in this thread.
Some detail: the Compex program increases the frequency gradually during the course of 25 minutes. Every four minutes the frequency increases by 1 Hz, thus at the end you reach 9 Hz. At Globus we tested this against cycles taking 5 minutes, and repeated four times. Then we tried the same with even shorter cycles. Users manifested their preference for the shorter cycle, they also volunteered that they were obtaining their recovery faster. Therefore we were able to shorten the program from 25 to 20 minutes. Younger subjects even claimed they needed only 15 minutes.
If you use the programmable version of the Globus Premium, you should be able to try your own variations of the program and find out for yourself what works best.
Personally I use “the Stick” (do a google search) to address IT band tightness. You can use EMS on the VMO. This does not address IT band tightness directly but may help the knee pain.
IT band tightness = is the symptom of something else? Like tight hamstrings and or quads or glutes? I don’t know but the EMS can be used to address any of these large muscle groups initially through an active recovery mode or something that will promote blood flow to loosen the area.
Sounds to me that you need to combine several approaches to get a result.
Massage, epson salt, contrast therapy and follow up with EMS and Travel Roller or a stick or something in this category.
Are both knees bothering you?
I was told a long time ago sprinters often do not address the tband and over time it can lead to issues with your knee. Find someone knowledgeable to show you proper stretches for your hamstrings and quads.
Yes my IT band tightness/ knee pain is a symptom of chronic tight quads/gluts/hip flexors. I have used massage/stretching/foam roller which gives temp relief.
I was thinking of buying a Globus EMS, to work out the knots/ break up any scar tissue in quad and hopefully loosen out IT bands/tendons around the knee. The quad is very tight beside the IT band,with lots of knots .
Both legs are tight, but right only has knee pain( walking up steps, bending) Also i have noticed my glutes feel weak when walking up steps.
I have no expereince of EMS, any advice would be helpful in terms of pad placement for loosing out the quad and the breaking down of knots/scar tissue etc.
I’m considering getting an ems unit depite being a little skeptical still (in terms of enchancements in power, recovery etc), what results have people here seen from them???
I bought an EMS unit a couple of years ago, and I have to say that spending at least a bit of extra money will get you a LOT more usability. First, if you can get a unit that will allow you to set the rest periods (as well as number of repetitions and sets) that allow for Charlie’s max contraction settings. Most inexpensive EMS units I found have rest settings of only 30 seconds, not the 50 seconds needed.
In addition, I think the number of channels and pads is really important. If you have four channels with two pads each, you can get through your max contraction work twice as fast as a basic unit. That’s a big deal over the long term!
In other words, you get what you pay for, so consider paying a bit more. You don’t have to go as high as buying a Globus. I bought this model:
It’s not bad for an entry level unit. The fact that it is a million times easier to use than a rudimentary unit means that you will likely use it much more often.
chalet fresh,
there is the vast experience shared by Charlie, the detailed information provided by gciriani and others, EMS works, nothing to be skeptical about. Provided its use is integrated in a sound plane, that’s for sure.
Chalet Fresh,
The reason many people don’t get results, is they don’t use the correct programs. Now, the link you showed is a cheap TENS, which will not allow you to train properly. I would suggest a unit that has the EMS parameter programmed in different protocols already labeled in the menus of the unit.
As in voluntary training, different EMS training protocols have to be employed for different goals you’d like to obtain. Take a look at the following table, to get a glimpse of the different protocols that you could use. In voluntary exercise you wouldn’t do 1 rep at 95% of 1RM exercises to pursue the same training goals that you would pursue with 8 rep at 70%. There are about half a dozen parameters to set; getting a decent machine with ready made protocols takes you half way through it. The remaining other half of the way, since you are new to the field, is to work with a coach who is familiar with EMS.
