Does anyone have sources where I can find the contraction ratios (% shortening of muscle length during full contraction) of specific muscles?

I founde some textbooks stating that typical skeletal muscles can shorten up to 70% (optimally up to 30%) during contraction. However, I would like to look at muscles per region. This might seem...

Marcelo Guimarães Silva

Dear Egwuonwu,

I found some papers which I believe that can help you.

Sincerely yours.

Afamefuna Victor Egwuonwu

Marcelo Thank you for the materials!

Mirta Widia

Hi Egwuonwo,

Usually the raw data of EMG is Microvolt. Then we will do the signal processing (feature extraction) of the raw data such as noise reduction, filtering, rectification to get the RMS then amplitude normalization. From EMG we will get the final data in MPF (Mean Power Frequency) or %MVC (Maximum Voluntary Contraction).

Thanks for the material Marcelo, really useful for me...

Mirta Widia you summarized it all.
