The energy sales in the human organism

Why does the organism energy?
The human body needs energy and nutrients to maintain its functions to be. Energy and nutrients, the body with food in the digestive tract open and where the individual nutrients released.

The tasks must meet the human body:
# Conservation of body heat
# Maintain physical functions (such as walking, muscle activity, digestion, body functions, etc.)
# Maintain mental functions
# Growth
# Regenerate lost body parts (such as skin, hair, fingernails)
# Metabolic activities

The energy needed, the organism from the Overstuff wench slung the food ingredients carbohydrates, fat and protein to some extent. The metabolic and products will arise about the breathing, the kidneys and intestinal Ret.

The energy needs of the human body
The energy needs the organism is transmitted from human to human and from day to day different.
The energy requirements will be divided into two groups:
Total energy demand = basic sales revenue performance

Basic Turnover (JV)

The JV is also known as resting fasting turnover means that it includes the production of energy to maintain all vital functions in hibernation.
The reason turnover is the amount of energy a person in 24 hours in complete silence and lying to maintain body temperature and for the basic metabolism (heart activity, breathing, etc.) on average.

The main factors that influence the GU:
# Age
# Sex
# Size and weight
# Hormones (especially thyroid)
# Percentage body composition (muscle mass in relation to the fat and bones)
# Build
# Stress
# Fever
# Drugs
# Climate

The average basic turnover is usually associated with 1kcal (4.2 kJ) per kilogram of body weight per hour.

JV = 1 kcal / kg / h
Example: A physically gut train inerter, 25jähriger man with a height of 1.85 m has a higher joint venture as a moderately trained 30-year-old woman with a height of 1.65 m.

Power sales
Any increase on the basic sales as well as sales performance.
Power sales = labor turnover leisure sales

The most important factors in determining sales performance:
# Muscle activity (e.g. sport, movement)
# Energy needs for growth (in children, adolescents and athletes)
# Warm ere gelatin (at different ambient temperatures)
# Digestive activity
# Mental activity (limited quantities)

Calculating the energy needs
Details of the amount of energy supply or energy demand made in calories (kcal) or joules (J).

1 kcal = 4.184 kJ
1000 kcal = 4.184 MJ (mega joules)
1 kJ = 0.239 kcal
1 MJ = 239 kcal

The valid unit of energy is kilojoules, but still the Kilocalorie as a unit.
If you kcal in kJ converts, it can be set to “4″ are rounded (1 kcal = 4kJ).
