I am searching study or journal that have published in terms of muscle activity value for each muscle during different tasks. Example: for lifting task, the significant muscle would involve in this task are erector spine and trapezius muscle.
Suggest you look for research publications by Chris Button, or Jim Cotter, of Havenith.
Hi,
What kind of Clinical applications are you looking for.
The approach should be double, every time a muscle is contracting the
Anyagonist
Hi Ovidiu,
i am measuring muscle activity on erector spinae and trapezius during lifting task for 30 minutes...so, i want to know how much is the normal muscle activity value for this kind of task...to verify my data
This is an important exercise with many clinical implication. Excellent! I found Dolan et al (look to the link I sent)
Also for a better understanding of the parameters u may use, like frequency of EMG or spectral power.. look attached file, is online access.
How do you plan to do? What device do you have? Neurophysiology device like Keypoint, Sinergy? Normally such a device have Spectral Power tool..
Please inform us of how you deal it!
Also, I suggest an intervention to your work! as using a pelvic belt (compare when using pelvic belt and when not... same subject but one week different times..)
As I said Antagonistic Rectus abdominalis or other abdominal muscles are important when controling the tonus of contracting muscles.. In the attached file you can see that using a pelvic belt produces lower frequency (less firing) meaning in my opinion more rendiment..
Best wishes,
Ovi

Thanks a lot for your information Ovi.
I use EMG to record the muscle activity. I use % MVC as my reference unit.
Ya, i also have read about the pelvic belt. But, unfortunately we don't have the equipment.
mmm, i cannot download the journal, my university don't subscribe the journal. Don't you mind to share the journal with me?
Thank you
I will send you the paper via message soon as I have to ask for it also:)
Pelvic belt, please check for Weightlifting Club in your city, they know very well what about and look to the link I shared here. It is about intraabdominal pressure.
The equipment is just a belt.. yes a little bit larger. Your work will then be applied to workers and sportsmen..:))
Best wishes, Ovi
