Hydrostatic Weighing or Underwater Weighing

The gold standard for determining body composition in humans, The individual is weighed while submerged under water, Makes use of Archimedes' principle


Inside of the muscle fiber, contain the contractile elements that shorten to generate force and move your bones during physical activity, There are three main types

Fast Glycolytic (FG) Fibers

Fast-twitch fibers that use almost exclusively anaerobic energy systems, Create the most force and power but fatigue rapidly

Fast oxidative glycolytic (FOG)

Fast-twitch fibers that use both aerobic and anaerobic energy systems

Adenosine Triphosphate (ATP)

The primary source of energy for muscle contraction, high-energy phosphate

ATP-Phosphocreatine System, Glycolytic System, Aerobic System

What are the three primary energy systems used to generate the ATP that muscles need during physical activity?

Muscular Strength

The maximal amount of force exerted by a muscle group

Muscular Power

The product of the force times the speed of movement

Muscular Endurance

The ability of a muscle to repeatedly exert force over a prolonged period

Isometric Exercise

Tension is produced without muscle length

Isotonic Exercise

Muscle changes length without changing tension

Isokinetic Exercise

Muscle changes length at a constant rate of velocity

Progressive overload

Training principle in which the exerciser must overload the muscle group in order for strength to increase


Increase in size of individual muscle fibers


Muscle fibers split and increase

Cardiac Output

The amount of blood pumped out of the heart each minute, function of both the heart rate and stroke volume

Stroke Volume

Amount of blood pumped per beat

Cardiovascular Endurance

Ability to exercise at moderate to heavy intensities for prolonged periods
