There has been an on going debate where biceps and triceps don't seem to benefit from stretch mediated hypertrophy because they have too many sarcomere in series that don't allow them to reach the descending limb length to experience passive tension. I read the study "Estimation of Musculotendon Properties in the Humans Upper limb" by Brian A. Garner and Marcus G. Pandy and here it showed that the biceps reached 1.25 which is very much on the descending limb length and If you graph it on opensim the biceps clearly go onto the descending limb in shoulder extension like an incline dumbbell curl, but there's also a study I can't seem to find that showed an incline curl didn't experience more growth for the biceps becuse of their length tension not reaching the descending limb. I am a bit sketchy on this because is stretch mediated hypertrophy even dependent on fascicle length and most of the studies that are on biceps show they beneift from lengthen positions, unless they are showing distal region growth and not stretch mediated hypertrophy. Does anyone have any thoughts on this?
