Our muscles comprise the largest part of our body.Indeed,they are the largest single organ of the body, and make up the bulk of its weight.All toghether,human have about 300 paired-muscles,totaling approximately 600 muscles.
Each muscles, or muscles group, has its unique function.Some muscles work alone, others work togheter in unison. The ammount of movements we posses, as a result of the combination of muscle fibers being utilized, are unlimited. Observe your hand and wrist, all this movement, each muscle has only one function, i.e.: to contract or relax. As one muscle group contracts (shortens), an opposing muscle group relaxes (lengthens).
It's that simple....or is it?
An absulotely perfect symphony of movements must take place for each step take. When you ate breakfast this morning, the muscles responsible for chewing had to contract, and relax, thousands upon thousands of times! In fact, to continue our example of breakfast, let's take a closer look at what was involved.
You used the muscles of your foot and toes, ankles, legs. thighs, and back to go to the table and sit down. The muscles of your eyes, neck, shoulders, chest, arms, wrists, hand, and fingers were all in motion. And lastly, of course the muscles of the face, which are responsible for chewing and swallowing, were working constantly.
And what's most amazing is we did't give it a single thought - it all "sort of" took place naturally!
The muscles of the human body are in use 24hours a day, 7 days a week, 365 days a year. Despite this enormous amoount of use, most of us spend little, or no, no time caring for our muscles. Obviously, with such extensive and continueed use, we must experience "wear and tear". In medical term, this is known as Repeatitive Strain Injury (RSI).
Let's face it; we are all creatures of habit. Which mean we tend to do the same things in the same way, over and over again. The way I brushed my teeth this morning was exactly the same way i brushed them before bedtime. That geos for yeaterday, the day before, and probably the last 10-20 years. The way we sit, stand, walk, drive, read a book, exercise, work at computer - and any other movement - are all-important elements to the condition of our muslces.
Whether you are a home maker or a construction worker...a typist or an interstate trucker... a musician or an electrician...the stress and strain placed on your muscles, each and everyday, is enormous!
