Front 1

air plethysmography

Back 1

a procedure of assessing body composition by using air displacement to measure body volume allowing the calculation of body density.

Front 2

bioelectric impedance

Back 2

a procedure of assessing body composition in which an electrical current is passed through the body. the resistance to current flow through tissues reflects the relative amount of fat present.

Front 3

body composition

Back 3

the chemical composition of the body .

Front 4

body density

Back 4

body weight divided by body volume.

Front 5

carbohydrate loading

Back 5

increased dietary consumption of carbs a process used by athletes to increase carb stores in body prior to prolonged endurance exercise.

Front 6

dehydration

Back 6

loss of body fluids.

Front 7

densitometry

Back 7

the measurement of body density.

Front 8

dual energy X-ray absorptiometry

Back 8

a technique used to assess both regional and total body composition through the use of x-ray absorptiometry.

Front 9

electrolyte

Back 9

a dissolved substance that can conduct an electrical current.

Front 10

essential amino acids

Back 10

the eight or nine amino acids necessary for human growth that the body cannot synthesize and are thus essential parts of our diets.

Front 11

fat

Back 11

a class of organic compounds with limited water solubility that exists in the body in many forms such as triglucerides free fatty acids phospholipids and steroids.

Front 12

fat-free mass

Back 12

the mass of the body that is not fat including muscle bone skin and organs.

Front 13

fat mass

Back 13

the absolute amount of mass of body fat.

Front 14

female athlete triad

Back 14

three interrelated disorders ; eating menstrual and bone mineral disorder to which some female athletes are prone.

Front 15

free radicals

Back 15

univalent (unpaired) oxygen intermediates that leak out of the electron transport chain during metabolic processes and may damage tissues.

Front 16

gastric emptying

Back 16

the movement of food mixed with gastric secretion from the stomach into the duodenum.

Front 17

glycogen loading

Back 17

the manipulation of exercise and diet to optimize the body's glycogen storage.

Front 18

hydrostatic weighing

Back 18

weighing body volume while fully submerged in water.

Front 19

hyponatremia

Back 19

a blood sodium concentration below the normal range of 136 to 143

Front 20

intracellular fluid

Back 20

the approx 60-65% of total body water that is contained in the cells.

Front 21

macrominerals

Back 21

those minerals of which the body needs more than 100 mg per day.

Front 22

microminerals

Back 22

the mineral of which the body needs less than 100 mg per day

Front 23

nonessential amino acids

Back 23

the 11 or 12 amino acids that the body synthesizes.

Front 24

osmolarity

Back 24

the number of solutes dissolved in a fluid divided by the volume of that fluid.

Front 25

protein

Back 25

a class of nitrogen containing compounds formed by amino acids

Front 26

relative body fat

Back 26

the ratio of fat mass to total body mass expressed as a percentage.

Front 27

skin fold fat thickness

Back 27

the most widely applied field technique used to estimate body density relative body fat and fat free mass.

Front 28

thirst mechanism

Back 28

a neural mechanism that triggers thirst in response to dehydration.

Front 29

vitamin

Back 29

one of a group of unrelated organic compounds that perform specific functions to promote growth and to maintain health.
