Can muscle swelling increase fiber growth?

In this part, I present the current scientific understanding about how (and why) our muscles swell with fluid following resistance training, and why this might actually change the structure of the muscle fiber to promote growth.

Hi does anyone know if the good Dr has a video on Hyperplasia and also Calisthenics? Just realised this video has touched on new fibre growth 🤦

This means more muscle is faster way to get more mature strenght

Hello Dr. Sandoo, thank you for these wonderful videos. Is the first reason for SH(edema due to the damage from eccentric contraction) causing the satellite cells to activate? If it doesn't; why the second reason activates the satellite cells and the first reason doesn't? Thank you very much 😌

Hi Federer, the trauma to the myofibers (i.e. the first reason) from eccentric training does stimulate satellite cell activity. In fact eccentric movements provide the greatest stimulus for muscle growth, which is why trainining modalities such as accentuated eccentric loading are so effective at increasing strength and hypertrophy.

@@physiologymadeeasy216 That is interesting, thank you for the additional information. Can very briefly explain the main difference between the first reason and the second reason? Thank you very much 🙂

If anybody can answer this I'd really appreciate it.
I've heard if you exercise on a consistent basis without eating any protein whatsoever, you can actually lose muscle. I want to know, does that muscle loss occur in the muscle you exercised, or are other muscles broken down to repair the one you exercised? My guess is the second. Is that right?

[@physiologymadeeasy216]

Hi Yoji, muscles fibres are made up of amino acids (protein), and training causes damage to the amino acid structure of the muscle. Thus, in order to get adequate repair, you need to increase protein intake. However, if you do not eat protein, you will get catabolism (protein breakdown in muscle). It is probable that this happens across all of the muscles in the body, perhaps starting with non-exercises muscles to begin with, but then also including protein breakdown in exercised muscle. Thus, it is better to either consume adequate amounts of daily protein as per normal recommendations, or substantially increase protein intake.
