Reading through these studies, which usually test normal subjects who haven't trained their bodies for 10+ years like most of us, has limited usefulness (but is interesting nonetheless). I just want to know why my middle finger tip joint always wants to lock up when I do fast alternation, and how to get rid of it. It seems to perhaps be a spastic bad habit, perhaps not directly related to anatomy. My a finger doesn't have that habit.
Again the study below is not guitar but piano players, but I think relevant. Amateur piano players use more force to get the same loudness and tempo compared to experts. Seems the same as for guitar i.e. it's about increasing awareness of unnecessary muscle activity, learning to relax, to do less, nothing to do with strength.
"To achieve the same tempo and the same loudness, amateurs applied significantly more and longer force to the keys"
"Years of experience enable the expert player to perform precise and reproducible motion patterns with an independent coordination of playing and non-playing fingers, an immediate relaxation of the playing finger after touch and a sense for the piano’s response."
"The amateur-group were surprised by the enormous amount of force they had applied to the nonplaying fingers. They were not aware of this waste of force and had no conscious sense for the cramping".
