Elements of Physical Fitness
There are several elements in supporting physical fitness in the body such as strength, endurance, agility, speed, balance, and so on. When you understand the elements of physical fitness, you can do exercises and sports that can support your physical fitness. Here are the elements.
Endurance is a condition where a person can move the body to do several activities with different tempos, but can do it efficiently and effectively without feeling excessive fatigue.
Endurance can be divided into two, namely, muscular endurance and cardiorespiratory endurance . Muscular endurance is endurance by showing the ability of muscles to do heavy work for a long time. While cardiorespiratory endurance is the ability of the whole body to continue moving at a moderate tempo for a long time.
Speed is the body’s ability to move from one place to another quickly. This speed is divided into three, namely, sprint speed, reaction speed, and moving speed. This speed can be trained by running based on an adjusted frequency.
Strength is the ability of the muscles to resist the load being carried by the body. This element of strength can also be called muscle strength. This muscle strength can also be related to muscle power or muscle endurance . Muscular endurance is the muscle’s ability to withstand contractions with light loads continuously.
There is a functional difference between muscle strength and muscle endurance . muscle strength is used to lift heavy loads in one activity. While muscle endurance is used to perform light physical activity for a long period of time.
Coordination is the body’s ability to perform activities or movements efficiently and accurately. A person who has good coordination then the cooperation done by his body will also be good. Concentration can also be done easily even while moving the body alternately.
Agility is the body’s ability to change body position quickly. With agility, the body will move quickly without the risk of injury. If agility has been formed in your body then you will easily move your body quickly without fear of making a mistake that will result in injury.
Flexibility is the body’s ability to perform maximum movement. This flexibility is supported by factors such as age, muscle quality, joint structure, and ligaments.
This flexibility should be trained often because flexibility is also related to other elements of physical fitness such as agility, speed, and coordination. Having a flexible body can minimize the risk of injury to the body. You can also move freely in all your activities.
7. Body Composition
Body composition is a comparison of the ratio of the body that has fat and lean mass. Fat mass is found under the skin, around the heart, intestines, around the muscles, and also the lungs. While the fat-free part of the body is in the bones, muscles, and body fluids.
The higher the fat mass, the higher your body has a risk of disease. Therefore, in order for your body to gain physical fitness, it is necessary to take care of the composition in the body.
Balance is where the position of the body will remain upright and not fall while performing physical movements. Having good body balance can minimize the risk of falling and injury.
9. Explosive Power
Explosive power is a combination of strength and speed, where the body can move quickly and also have strong muscles to fight the load carried by the body. This means that our body can move quickly and carry heavy loads at the same time.
10. Speed of Reaction
Reaction speed is the reaction time of your body when receiving a stimulus or stimulation. The speed of this reaction is different from the reflex. A reaction is a conscious movement, while a reflex is an automatic movement performed without awareness.

Factors Influencing Physical Fitness
In achieving optimal physical fitness for our body, there are several factors that can affect it. Here are the influencing factors of physical fitness.
In order to survive, humans generally need food. When it comes to food, we can’t just eat the food we see, but we must also look at the level of nutrition that can meet our health needs.
Therefore, it is best to avoid food and drinks that can damage our body such as alcohol and eat food that lacks nutrition.
Work on the human body has its limits, so be aware that your body should not work too hard. Fatigue is an indicator of the limits of human body function. It means that your body is no longer strong enough to support the body to do activities. If it’s like this, it’s best to rest enough to recharge the energy for the next day.
Age is an influence in physical fitness. At the age of 25-30 years physical fitness can increase to the maximum. Then it will also decrease the functional capacity in the body by 0.8 – 1% every year. If you are diligent in exercising, the decrease in body function will also decrease, even up to half.
