Muscle Origin and Insertion

One aspect of anatomy that helps with functional training exercises and sports performance is understanding muscle origin and insertion.   As an example lets look at Pectoralis Minor muscle.

Its origin is the 3rd, 4th and 5th ribs close to costal cartilages that connect the ribs to the breast plate. The insertion point is the medial superior surface of the coracoid process of scapula. In short it connects your ribs to the top of your shoulder blade and it pulls it down and forward.

Assuming that you have a stable scapula that is in its correct anatomical position, when you contract the Pectoralis minor, it helps you lift the ribs.

What would happen if your pec minor is too strong or too tight? It pulls the insertion towards the origin that means it pulls the scapula up and over towards your breast plate and gives you a rounded shoulder look.

This pattern of moving the insertion point toward origin repeats in many muscular imbalances.  When you are clear about this, you’ll recognize a poor posture, many of shoulder weakness and injuries as well as lack of strength in shoulder motions could be connected to the pull the pec minor exerts to move the insertion towards its origin.

You also recognize that one of the first steps in improving your posture, getting relief from shoulder pain and improving your shoulder strength is to reduce the tension within the pec minor.

 

How To Learn Anatomy

Anatomy learning like other forms of successful learning begins with love.

Think about a person who loves computers and technology. She can describe every detail of her ipad down the thickness of it. She can hold conversations about various models, various aps and why ipad is so much better than a pc for example.

How about a guy loves vintage cars? They know exactly when power steering was installed on corvette and that only 12% of cars had it.

Ask the same lady where her patella is and the same guy why he is having low back pain and they are baffled. Don’t even bother asking about the location of diaphragm.

They have learned the anatomy of an ipad and a car but not anatomy of a human body.

You too love something and know a lot about it. For you to continue doing what you love and learn more about what you value, at least a basic knowledge of human anatomy is essential.

If you are working out or planning to begin a fitness program, your enjoyment of the process and your success depends on your knowledge of the basics. One of these basics is human anatomy.

If you love anatomy, you’ll find ways to learn it. If not, find easy ways to learn the parts of anatomy that applies to you.  Pain and performance are two good starting points.

If you have pain in any part of your body, get some flash cards of the area and learn about it. If you want to improve your performance in a sport you love, let say golf, learn about the intricate connections of nerves, blood vessels, , muscles, tendons,  ligaments and bones that control the swings.

Your appreciation for anatomy increases with your learning as does your performance. You may even stumble on how your anatomy impacts your health. For example, how placement of your head over your shoulder and the nerve signals that control your body from your neck down.

With increased knowledge of your body, comes increased awareness of how it works. You begin to distinguish between various types of pain in your body and take steps to treat them and not mask them with pain killers.

You may never develop the love you may have for technology or vintage car or any other hobbies you enjoy, but you could develop a deep and beneficial appreciation for how your knowledge of anatomy helps you do what you enjoy.

Biological Clock Theory

Dawn and dusk chase each other daily as does summer and winter. These are natural cycles of life. When these cycles happen in a human body they are called “biological clocks.”

According to the biological clock theory, every rhythm within the body has an order. Your heart beat, your breathing patterns and body temperatures are a few aspects of these internal rhythms. Some peak during the day and some at nights.

Another name for the biological clock is “circadian rhythms.”

We are not separate from our environment. Many of our rhythms match or are influenced by the rhythms of our surroundings. Sleep is a good example. In nature as it gets dark we prepare to go to sleep. Some of our rhythms continue even when we are placed in isolation.

Some experiments indicate that the body’s inner clocks would not change even if a person was isolated for weeks from any social or physical cues, such as a regular meal or light-dark cycles.

Body temperature is a well studied circadian rhythm. In a healthy person, it is at its lowest in early hours of morning and peaks in the late afternoon. The relative change is independent of routines.

Blood sugar level also decrease by noon. Around 3:00 a.m. to 6:00 a.m. your body has depleted much of its sugar supply. This is one reason many suggest early morning aerobics workouts so that your body burns fat since it has very little sugar to burn.
