MUSCLE/BUILDING MUSCLE– UDERSTANDING MUSCLE — OBESITY

Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.

Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth.

Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.

[1] Skeletal muscles in turn can be divided into fast and slow twitch fibers.
Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers.

These chemical reactions produce adenosine triphosphate (ATP) molecules that are used to power the movement of the myosin heads.[2]
The term muscle is derived from the Latin musculus meaning “little mouse” perhaps because of the shape.

RESOURCE (WIKIPEDIA)

Obesity is a medical condition in which excess body fat has accumulated to an extent that it may have a negative effect on health.

[1] People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person’s weight by the square of the person’s height, is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight.

[2] Some East Asian countries use lower values.[8] Obesity increases the likelihood of various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, osteoarthritis, and depression.


PROTEINS

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, and organisms, and transporting molecules from one location to another.

Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity.

PHYSICAL FITNESS IMPROVES ENDURANCE

Physical fitness improves endurance

Engaging in regular physical activity had been proven to be the main contributing factor to increasing the body endurance level. When you do more exercise the heart and the muscle respond by rebuilding and regenerating, thereby preparing the body for more.

And by doing the more, the cells of the body are challenged. The cells rise up to the challenge by making the heart to recover faster and more blood are supplied to the muscles. When these happen, the endurance level of the body improves.

The performance of the cardiovascular system (heart) during physical activities determines endurance level. And this can be measured by three key variables. These are:

i. the number of times the heart beat in a minute (rate of heart beat)
ii. amount of blood pumped by each heart beat (stroke volume), and
iii. the force of contraction exerted on the heart muscle (heart contractility)SUPPLEMENTS/REIDUAL INCOME

One of the best ways to improve these variables is by engaging in more physical activities. With these, more blood will be delivered to the muscles, the heart recovers quickly and more vessels process the increased blood and oxygen.
Apart from the heart, there are other determinants of endurance performance. The muscle during physical activity drive the flow of blood through the veins and back to the heart. Increasing the amount of blood delivered to your heart. In other words, we can say that the muscles improve the stroke volume of your heart during exercise.CLICK NOW SUCCESS RESIDUAL INCOME

In addition, the mitochondria (powerhouse of the cell) of the muscle cells increase to enable the muscles to do more work. They efficiently burn more body fat and store glycogen by using oxygen to produce ATP energy. These allow you to work longer and harder without suffering fatigue. The regular contraction and relaxation of the skeletal muscles is also a contributing factor to endurance performance.

You will notice that there is a connection between the cardiovascular system and the body muscles. This shows that in order to build endurance, you need to improve the performance of your heart and muscles.

Endurance performance can be improved by engaging in physical activities such as walking, cycling, jogging and swimming. These are examples of endurance or aerobic exercise. They help to increase your heartbeat rate and breathing. Endurance exercise keeps the cardiovascular system, lungs and muscles healthy and improves the overall physical fitness of the body.

As mentioned above, regular physical exercise is very essential as far as endurance is concerned. But you also need to maintain a healthy eating habit. Your foods should be rich in high quality protein, healthy carbohydrates such as whole grains and drink lots of water. Sleep is also important.

In conclusion, the rate of the heartbeat, amount of blood supplied to the heart, the heart contractility and the amount of oxygen the muscles can effectively processed affect your endurance level. And all these can be improved by working on your physical fitness. Therefore, physical fitness can improve the endurance performance of the body.
