Articles on Muscle Adaptation
   by Geoffrey Goldspink and others

 
The following articles concern the different types of muscle fibres (red slow-twitch fibres, white fast-twitch fibres and intermediate fibres) and how they can change from one type to another.

These articles are copyright by their authors, I have only gathered them together here and formatted them for easy reading and/or printing.  In most cases the original Internet URL is in the document so you can go to their original location.

8. Summary of Research on Muscle Training     PDF file  (642 Kb)

"Skeletal muscle is the most abundant tissue in the human body and also one of the most adaptable. Vigorous training with weights can double or triple a muscles size, whereas disuse, as in space travel, can shrink it by 20 percent in two weeks. The many biomechanical and biochemical phenomena behind these adaptations are enormously complex, but decades of research have built up a reasonably complete picture of how muscles respond to athletic training..."
A summary of research on muscle adaptation and rehabilitation. This article is related to the above but by different authors.

9. 'Marathon Mice' Elucidate Little-known Muscle Type     PDF file (A4-size)  (32 Kb)
'Marathon Mice' Elucidate Little-known Muscle Type     PDF file (8.5x11-size)  (32 Kb)

Article about research on a new fourth sub-type of muscle, type IIx, which seem to have the oxidative metabolism of slow-twitch fibres mixed with the biophysical properties of fast-twitch fibres giving them an efficient way of generating energy combined with higher work loads.


 

Directions for printing PDF files

Steps to print from Adobe Acrobat:

1. Choose "Page Setup" from the "File" menu and select the correct "Paper Size" from the drop-down list — e.g. A4 size for Europe or 8.5" X 11" (letter) for N. America, and then click on "OK".

2. Choose "Print" from the File menu and make sure the "Fit to Page" or "Scale to Page" box is checked. The other boxes in the same area should be unchecked.

3. Make sure your printer is on and has the correct paper loaded, then click on OK.   That's it.
