Af Plus Weight Loss

muscles. we have over 600 of them. they make up between 1/3 and 1/2 of our body weight, and along with connective tissue, they bind us together, hold us up,and help us move.

Af Plus Weight Loss, and whether or not body buildingis 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 you're standing in front of a door,ready to pull it open. your brain and muscles are perfectlypoised to help you achieve this goal. first, your brain sends a signalto 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 armand generate the needed movement. the bigger the challenge becomes,the bigger the brain's signal grows, and the more motor units it ralliesto help you achieve your task. but what if the door is made of solid iron?

at this point, your arm muscles alone won't 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 leveragedthe 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 releaseinflammatory molecules called cytokines that activate the immune systemto 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 adaptedto most everyday activities, those generally don't produce enough stress to stimulate new muscle growth. so, to build new muscle,a process called hypertrophy, our cells need to be exposed to higherworkloads than they are used to. in fact, if you don't continuously exposeyour muscles to some resistance, they will shrink,

a process known as muscular atrophy. in contrast, exposing the muscleto a high-degree of tension, especially while the muscle is lengthening, also called an eccentric contraction, generates effective conditionsfor new growth. however, muscles rely on more thanjust activity to grow. without proper nutrition, hormones, and rest, your body would never be ableto 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 factorand testosterone, help shift the body into a statewhere tissue is repaired and grown. this vital repair process mainly occurswhen we're 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 rolein one's ability to grow muscle. some people have more robust immune reactions to muscle damage, and are better able to repairand replace damaged muscle fibers, increasing their muscle-building potential. the body responds to the demandsyou place on it. if you tear your muscles up,eat right, rest and repeat, you'll create the conditions to make yourmuscles as big and strong as possible. it is with muscles as it is with life:

meaningful growth requires challengeand stress.
