Physical Fitness – What is it? How to get it?

Most humans realize it or want to increase their practice, in order to have good health and fitness road, but never ask ourselves, what is physical activity?

Caspersen, Powell and Christenson physical activity defined as “any bodily movement produced by skeletal muscles that results in energy expenditure”. Doctors propose a simple but interesting formula to find the total energy expenditure that we have every day; and is as follows:

Sleeping + Occupation + Leisure -> Total Daily Physical Activity

This formula is used to give a basic idea of ​​what the daily calorie expenditure and how we can balance it with food; moreover, the formula used to give a clear answer, a variable that perhaps is the aim of all those exercisers who is: The Physical Fitness.

What would be physically fit, what would fit? Doctors define fitness as follows: “Ability to carry out daily tasks with vigor and alertness, without undue fatigue and with ample energy to enjoy leisure time.”

Being physically fit not only means a nice body, but in a deeper and useful internal state, used to live everyday with full intensity.

According to studies by Caspersen, Powell and Christenson, a person who is physically fit, should meet these requirements:

  • Cardiorespiratory Endurance
  • Muscular Endurance
  • Muscle
  • Body Composition
  • Flexibility

So every person should consider personal goals according to their needs and try to meet the requirements that are important.
