Key Roles of Muscle and Bone for Proper Exercise

Key Roles of Muscle and Bone for Proper Exercise | As a matter of fact, exercise has many merits. Starting from exercise may improve your cardiovascular endurance, boost your strength, and keep your healthy weight as well as may avoid you getting many diseases, for example, diabetes and high blood pressure.  Most people may know those benefits for muscle, but forgetting about exercise also benefits your bones. Have you thought about exercising to strengthen your bones or prevent fractures? There are many excuses why you need to have strong bones. Bones not only present as a framework for your body, but also possess important roles, for example, protecting your vital organs, making blood cells, and storing minerals. In addition, unhealthy bones may cause bone fractures that result in prominent morbidity and limit your daily activities.  

That is why it is essential to strengthening your muscle and bone through exercise. Training your muscle and bone may also prevent you from muscle injury and bone fracture. And, if you are having those injuries, you may seek a chiropractor’s help. If you want to know what a chiropractor is, you may read this article about them here But, before you want to exercise to strengthen your muscle and bone, you have to know:

  •  What are Muscles and What They Do?

Do you know why your body can move? Yes, that is muscle doing. Muscles pull on your joints and allow you to move your body, walk with your leg, and even run. They also support your body to do more things such as chewing foods and then assist them in moving through your digestive system. In fact, while you are sitting perfectly still, your muscles in your body are still working. Those muscles assist the heart to beat, the chest to move up and down while you are breathing, the blood vessels to regulate the pressure and flow of your blood. Even when we smile and talk, muscles also help us communicate with each other, and of course, when we exercise, they help us stay healthy and physically fit. 

According to several sources, the movements which muscles make are coordinated and controlled by the brain and nervous system. The smooth or involuntary muscles are controlled by structures deep within your brain and the brain stem which is the upper part of your spinal cord. These muscles are also regulated by the cerebral motor cortex and the cerebellum which are also the parts of your brains. When you want to move your body, the motor cortex sends an electrical signal through the spinal cord and peripheral nerves to your muscle and makes them contract. Then, your right side of the brain, which is the motor cortex, manages the muscle on the left side of your body to move and vice versa.   

The cerebellum synchronizes the muscle movements which are ordered by the motor cortex. Sensors in the muscles and joints transmit the instruction back through peripheral nerves to inform the cerebellum and other parts of the brain about where and how the arms or legs are moving and what position we want. This reaction produces smooth and coordinated motion. If you desire to raise your arm, your brain will transmit the instruction to the muscles in your arm and you will move your arm. Also, when you want to run, the instructions to the brain are more concerned, because many muscles have to work in harmony. 

Muscles budge your body part by contracting and then relaxing itself. Muscles may pull the bones but they cannot push them back to the original position. Therefore, they perform in pairs of flexors and extensors. The flexor contracts to bend a limb at your joint and then, when your movement is completed, the flexor is relaxing and the extensor is contracting to straighten or extend the limb at the same joint. For instance, the biceps muscle, in front of the upper arm, is a flexor and the triceps at the back of the upper arm is an extensor. When you want to bend your elbow, the biceps will contract, then, the biceps will relax and the triceps will contract to straighten your elbow.

  •  What Are Bone and What They Do?

Bones give support for our bodies and they help our body to establish our shape. Even though bones are very light, they are strong enough to help you sustain your body. Another function of bone is protecting your body’s organs. For instance, your brain is protected by your skull, in addition, the skull forms the shape of your face. The spinal cord, a route for interaction between your body and your brain, is protected by the backbone or spinal column. What is more, your heart and lungs are protected by the ribs which form like a cage, and the pelvis assists you to protect the bladder, part of the intestines and in women is the reproductive organs.

Bones are made up of a composition of a protein which is well known as collagen, to strengthen and make the bones hard you need a mineral such as calcium and phosphate. Calciums is stored in your bones and some of them will be released through the bloodstream when they are needed by other parts of your body. The amounts of vitamins and minerals that you consume, especially vitamin D and calcium, will affect directly how much calcium will be stored in the bones.   

  • Muscle and Bone During Exercise

Muscle and bones are close to each other but have you thought that bone actually may influence muscle in any way? While you are exercising, your bone releases a hormone called osteocalcin which may escalate your muscle performance, according to one new study.  Osteocalcin naturally falls off in humans as we age, it starts in men at age 50 years old and women at age 30 years old. This new study may describe the first bone-derived hormone known to affect exercise capacity and shows that osteocalcin injection can reverse the age-related workout capacity decline in mice. That is why your bone may have a key role to make your muscle more strength and more endurance through exercise.
