Fat’s enemy - Epinephrine

Deposition of fat in males and females is physically obvious to the eye and has been a source of great discussion over the years, from faddish diet plans, designed to burn it off, so to speak, to surgical intervention procedures (liposuction) .
Males tend to store fat around their waists (android apple body shape) whereas females tend to store fat around the hips (gynoid or pear shaped).
The android shape is associated with a greater risk of cardiovascular disease. The process in which lipolysis (fat released from cells and utilized as an energy source in aerobic respiration) occurs is a series of events influenced by body conditions.

It is important to understand that mobilization of fat refers to the release of fat from fat accumulation areas in the body and metabolism of fat is the complete biological breakdown of fat in a process called oxidation (meaning the loss of electrons from a molecule and utilised as a source of energy).

Fat is stored in the form of three fatty acids and glycerol (a form of alcohol) plus in the form of droplets in musclo-skeletal cells, each droplet is 3000 kcals of stored energy. For this to be released two enzymes are needed, one being hormone sensitive lipase HSL and lipoprotein lipase or LPL.
HSL is positioned directly in the cell of fat and is activated by the hormone called epinephrine. When HSL is activated the process begins to break apart the free fatty acids and glycerol from the adipose cell and release it into the bloodstream and this process is called lipolysis.

The role of the hormone epinephrine which is released by the sympathetic nervous system during exercise is understood to the initial activator of lipolysis.
Receptors on fat cell are latched onto, or binded to, by epinephrine, which is in greater concentration during higher body temperatures during aerobic exercise and resistance training exercise which must be carried out at the correct level of intensity. The higher body temperature increases the fat cells sensitivity to epinephrine.

As a personal trainer I would manipulate these physiological facts and incorporate them into training I would prescribe clients thereby maximizing fat burning both during and after cardio and resistance.
Post metabolic rate would be of a significant level to cause an after burn which would break down fat even after the client has finished his/her session.
