Hi,
Yes I'm new here in this forums.
Most of the papers that dealing with experimental data of skeletal muscles do not contains the raw data, just their figures or a part of these data. Also, some of them mentioned a link to their data on line which is not available any more. Besides, trying contacting them through e-mail.
However, the purpose from the data is to use it for modifying one of the non linear functions of the active muscle force-length.
Regards,
