which statement best describes how muscles respond to weight training? This is a topic that many people are looking for. g4site.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, g4site.com would like to introduce to you What makes muscles grow? – Jeffrey Siegel. Following along are instructions in the video below:
We have over 600 of them they make up between 1 3. And 1 2 2 of our body weight and along with connective tissue they bind us together hold up and help us move. And whether or not body building.
Is your hobby muscles need your constant attention. Because the way you treat them on a daily basis determines. Whether they will wither or grow.
Say youre standing in front of a door ready to pull it open your brain and muscles are perfectly poised to help you achieve this goal first your brain sends a signal to motor neurons inside your arm when they receive this message they fire causing muscles to contract and relax. Which pull on the bones in your arm and generate the needed movement the bigger. The challenge becomes the bigger the brains signal grows and the more motor units it rallies to help you achieve your task.
But what if the door is made of solid iron at this point your arm. Muscles. Alone wont be able to generate enough tension to pull it open.
So your brain appeals to other muscles for help you plant your feet. Tighten. Your belly and tense your back generating enough force to yank.
It open your nervous system has just leveraged. The resources you already have other muscles to meet the demand.
While all this is happening your muscle fibers undergo another kind of cellular change as you expose them to stress. They experience microscopic damage. Which in this context is a good thing in response the injured cells release inflammatory molecules called cytokines that activate the immune system to repair the injury.
This is when the muscle building magic. Happens the greater the damage to the muscle tissue the more your body will need to repair itself the resulting cycle of damage and repair eventually makes muscles bigger and stronger as they adapt to progressively greater demands since our bodies have already adapted to most everyday activities those generally dont produce enough stress to stimulate new muscle growth. So to build new muscle.
A process called hypertrophy our cells need to be exposed to higher workloads than they are used to in fact if you dont continuously expose your muscles to some resistance. They will shrink a process known as muscular atrophy in contrast exposing the muscle to a high degree of tension especially while the muscle is lengthening also called an eccentric contraction generates effective conditions for new growth however muscles rely on more than just activity to grow without proper nutrition. Hormones and rest your body.
Would never be able to repair damaged muscle fibers protein in our diet preserves muscle mass by providing the building blocks for new tissue in the form of amino acids adequate protein intake along with naturally occurring hormones like insulin like growth factor and testosterone help shift the body into a state. Where tissue is repaired and grown this vital repair process mainly occurs when were resting especially at night. While sleeping gender and age affect this repair mechanism.
Which is why young men with more testosterone have a leg up in the muscle building game. Genetic factors also play a role in ones ability to grow muscle some people have more robust immune reactions to muscle damage and are better able to repair and replace damaged muscle fibers increasing their muscle building potential. The body responds to the demands you place on it.
If you tear your muscles up eat right rest and repeat youll create the conditions to make your muscles as big and strong as possible. It is with muscles as it is with life meaningful growth requires challenge and stress. .
