How Do Muscles Work?
We all have them, but most of the time we pay no attention to them, unless of course we pull them in some way or exercise them too much so they ache a bit! But muscles are essential for movement because:
• They convert energy into the motion, just as a car engine makes your car run.
• Basically, you couldn’t do anything without muscles. For example, muscles in your larynx, mouth and tongue help you to speak, skeletal muscles help you to walk, run, climb, exercise and dance – these are the muscles that control voluntary movements.
• Muscles also help control body movements that you generally never even think about – your breathing, heart beat, facial expressions, food digestion, eye movements, blinking and other involuntary movements.
Without muscles – you wouldn’t be able to live very long, that’s for sure. Humans have more than 650 muscles, which make up more than 40% of your body weight. Heavy stuff!
How do muscles move? Well, muscles are made up of cells that contract and then relax. These cells use energy from the food you eat to do this, so without food, and the nutrients it provides, your muscles would be too weak to perform as they should.
Can you hurt muscles? Sure, you can and you often hear people say they have “pulled” a muscle, meaning it has been torn, similar to breaking a bone. However, unlike most bones that have to be re-set, muscles are self-healing.
Some fun facts about muscles:
• It really does take more muscles to frown (12) than smile (10)!
• Your eye muscles move more than 100,000 times each day!
• The smallest muscle is in your ear – it’s called the stapedius.
One way to improve the way your muscles work is to exercise! Exercise makes your heart beat faster, sending more blood out to your muscles, giving them the vital oxygen and nutrients they need to work properly. And when you exercise, your digestive system slows down to conserve energy that your muscles need.
But don’t forget muscles only move when commanded by your nervous system—the focus of your chiropractic care. Which is one reason athletes and those who want to be their best seek regular chiropractic care.
