Know thyself. The Muscular System.
In our continuing series know thyself, we unpack the most amazing of Gods’ work which was the summit of creation. God Himself created man with his own hands out of soil of the earth He had earlier spoken to existence. Man is both physical and a spiritual being. We exist both at the conscious and subconscious levels. When we sleep, we move into the subconscious realm. When we are awake, we operate at physical level and fully conscious of our environment.
The body of man is the temple of Holy spirit. This is recorded 1 Corinthians 6:15. We cannot fully comprehend our complex body especially the spiritual level but we have a good understanding of our physiology. This enables us to take good care of our health to operate at optimum.
Last week we unpacked the skeletal system. Come with me we learn about muscles that support the bones and joints.
The muscular system is the organ consisting of skeletal, smooth and cardiac muscles. The muscles are made of elastic tissue fibers called myofibrils. Composed of different types of proteins. Amino acids are the building blocks of protein. There are nine essential amino acids, but there’s a key trio that helps in maintaining the muscles: leucine, isoleucine, and valine. Of these three, leucine is the muscle-building powerbullet.
In this article, we will focus on skeletal muscle. The other two we will handle them later.
Skeletal muscles are those that cover the bones and give the body its shape. These muscles facilitate movement between the external body parts and the limbs. The skeletal muscles are connected to strong tendons attached directly to the bones. We can consciously control most skeletal muscle functions.
Most of the movements that we can see occur when the skeletal muscles contract. There is about 320 pairs of bilateral muscles in our body. They work in pairs. When one muscle contracts, the other expands to support movement as commanded by the brain. Every movement is controlled by the brain.
Moving the eyes, head, arms, walking, running or Jogging. Facial expressions such as smiles, frowns, mouth, and tongue movements are all functions of the skeletal muscles.
Skeletal muscles helps the body to maintain posture. The muscles continuously make tiny adjustments to maintain posture. They keep a person’s back straight or hold their head in one position. The bones need to be kept in the right position so that the joints do not dislocate. The skeletal muscles and tendons support the joints to remain in position.
Types of skeletal muscles.
There are two main types of skeletal muscles, slow twitch or fast twitch muscles.
Type I; slow twitch muscles:
These are dense and have capillaries. They are rich in myoglobin and mitochondria. This gives them their red color. This type of muscle can contract for a long time without much effort. Type I muscles can sustain aerobic activity using carbohydrates and fats as fuel.
Type II fast twitch muscles:
These muscles can contract rapidly and with a lot of force. Contraction is usually strong but short-lived. This type of muscle is responsible for most of our muscle-strength, and our increase in mass after periods of weight training. It is the least dense in myoglobin and mitochondria.
Ways of maintaining stronger muscles.
Habitual sedentary behavior increases weakness of the muscles. Short-term bed rest accelerates the loss of muscle mass, function, and glucose tolerance by destabilizing metabolic homeostasis muscle mass and function. This is because muscle protein synthesis are negatively affected by muscle disuse.
The human body is made for activity. Every time you lift, press or pull some weight, you create microscopic tears in your muscles. Your body then responds with signals to repair your muscles. Continuous exercise overtime leave you with improved muscle mass and strength.
Performing aerobic exercise—such as swimming, walking and running or even gardening—between 30 and 60 minutes 5 days a week and you incorporate healthy protein-rich foods like fish, Lentils, Chickpeas and Most Varieties of Beans, Nutritional Yeast, Spelt and Teff, Hempseed, Green Peas. Also, watch your vitamin D levels. Lower levels can affect muscle strength.
