A

Adaptive Thermogenesis

The decrease in energy expenditure by the body over time as a result of being in an energy deficit.


B

Basal Metabolic Rate (BMR)

The minimum amount of energy  needed by the human body to function at rest.


C

Calorie

A unit of energy used by the human body. 2 main definitions exist:

  1. Cal =  a small unit of calories defined by the gram and is the amount of energy needed to raise the temperature of one gram of water by one degree Celcius at one pressure of atmosphere.
  2. Kcal = a large unit of calories defined by the kilo. 1 kcal is the equivalent to 1,000 calories.

The kcal is the unit used for measuring calories in food.

Compound Exercise

Any exercise that works multiple muscle groups through multiple joint actions i.e. the bench press which works the chest, shoulders and triceps and requires movement at both the shoulder and elbow joint.

E

Energy Balance (Energy Balance Equation)

  2. Energy input < energy output = weight loss
  3. Energy input = energy output = weight maintenance

O


P

Progressive Overload

The intentional act of exposing your body to a greater stimulus that it has experienced previously to provide the necessary incentive to make it adapt by getting bigger, stronger, faster, etc.
