Hi & thank you for this video. Can you name scientific sources that support longitudinal sarcomere adaptation? I'm wondering because after extensive research I found contradicting statements about this. i would really appreciate if you can help me out with this. Claire
Hey! Does sarcomeres added in series change the whole muscle length at rest? For example, people say: my hamstrings are short/tight, does this possible? I heard that stretching is all about gaining more tolerance to stretch rather than change of whole muscle length? Thanks!
static stretch increase your neurological tolerance, that means your neurological receptor can get used to greater stimulation like greater static stretch, however if you do static stretch in a long term, it can reduce your musculotendinous stiffness as well. In summary, appropriate time and stress are key factors to reduce stiffness but static stretch overall can generally increase neurological tolerance.
Great explanations! Do you have any references I could delve into regarding sarcomerogenesis? I'm doing my graduation project on hypertrophy and it would be of tremedous help.
Thanks for the video :) Does sarcomeres added in series also increase lengthening capacity or is that for adding it in parallel? I would assume parallel
Shortening capacity would be the maximum a muscle contract until the actin and myosin filaments are at their max. If you could theoretically only flex your bicep to 90 degrees, increasing the amount of sarcomeres in series would literally make the muscle longer. With a muscle that's longer it has more capacity to contract further and your bicep would get closer and closer to pulling your arm to your shoulder.
