Physical Activity Level (PAL)
The PAL, also achievement conversion, describes the amount of energy that is needed in addition to the metabolic rate in order to achieve physical performance.It is decisively influenced by the physical activity of the respective person. The measurable value of the activity is called the PAL value. Even light activities such as sitting, standing or office work increase the achievement conversion. Heavy physical work or endurance sports significantly increase the daily energy demand.
