Examples may range from those who run marathons, a weightlifter, gymnasts or even beach bums with six-pack abdomens.
It is surprising that even exercise physiologists are having a hard time answering the question on physical fitness. For decades they didn’t have a simple and straight answer to its definition.
Simply put physical fitness is a measure of the body’s ability to function efficiently and effectively be it in work and leisure activities. It is part of one’s health resources.
As this is the short answer, by breaking down individual components of physical fitness, there will be a more interesting and a longer answer. The answer to what physically fit means will be clearer in identifying, measuring and assessing its significance.
There are metrics on physical fitness with five being health related while the other five are skill related. The latter are to be improved through motor skill practice.
The Composition Of The Body
By definition, it is the relative amount of bone, fat, muscle and the rest of the body parts considered vital. This is considered the only non-performance metric compared with the other metrics.
It is also one reason why it is at times excluded in the list of physical fitness measurement.
Even with a high degree of fitness, it is possible for an individual to have excess fat amount in the body. Other general health markers are to be considered. Losing body fat while retaining lean muscle will improve all the rest of the physical fitness metrics. There will be a given improvement on the strength/power to weight ratio too.
What Is Your Strength?
One’s ability to exert force of a muscle group is the definition of strength. It may be measured with multiple tests in more than one muscle group. Exercises like the squat, bench press, or deadlift are examples of producing a maximum effort to measure.
Strength is important in everyday life. Bending, pushing and pulling are daily activities we do. As we age, size and strength of muscles decrease and so does bone mass. Through strength training, these can be reversed.
For The Heart
To be able to supply oxygen by the circulatory and respiratory systems during sustained physical activity is the definition.
As the heart does not have to work as hard to pump blood to the muscles, it is well worth maintaining at a level of fitness. A very healthy heart increases the lung capacity. Lifestyle diseases are also kept at bay if the overall cardiovascular health is tiptop.
The ability of the joints to attain different ranges of motion is flexibility. As there are many joints in the human body there is no specific tests that may be specified.
A range of stretches may become a flexibility identifier. Examples of these are the sit and reach test and the shoulder reach.
If the ranges of motion about various joints are limited, it has a direct effect on the other aspects of physical fitness. You may not be able to utilize a big part of your movements. If the flexors are tight, one’s maximum speed may not be attained or the agility is impaired.
Enduring The Activities
One’s ability to continue performing repeated contractions of the muscles against various resistances is called the muscular endurance.
It will be considered as having great endurance if one-person experiences less fatigue in doing repetitious physical activities like gardening, washing the car, doing household chores.
