ISSA Flashcards
Training effect
An increase in functional capacity of muscles and other bodily tissues as a result of increased stress (overload) placed upon them.
Homeostasis
The automatic tendency to maintain a relatively constant internal environment.
metabolism
The total of all the chemical and physical processes by which the body builds and maintains itself (anabolism) and by which it breaks down its substances for the production of energy (catabolism).
glucose
Principal circulating sugar in the blood and the major energy source of the body.
amino acid
he building blocks of protein. There are 24 amino acids, which form countless number of different proteins.
metabolic set point
The base rate of metabolism that the body seeks to maintain; resulting in basal metabolic rate.
BMR
The minimum energy required to maintain the body’s life function at rest; usually expressed in calories per hour per square meter of the body surface.
thermic effect
The heat liberated from a particular food; it is a measure of its energy content and its tendency to be burned as heat. This process of heat liberation is also commonly referred to as “thermogenesis.”
respiratory quotient (RQ)
ratio of the volume of carbon dioxide expired to the volume of oxygen consumed.
adenosine triphosphate (ATP)
n organic compound found in muscle which, upon being broken down enzymatically, yields energy for muscle contraction.
creatine phosphate (CP):
A high-energy phosphate molecule that is stored in cells and can be used to immediately resynthesize ATP.
ATP/CP pathway
- is anaerobic, which means it requires no oxygen for energy use
- ATP and CP provide anaerobic sources of phosphate-bond energy. The energy liberated from hydrolysis (splitting) of CP re-bonds ADP and Pi to form ATP.
adenosine diphosphate (ADP)
an organic compound in metabolism that functions in the transfer of energy during the catabolism of glucose, formed by the removal of a phosphate molecule from adenosine triphosphate (ATP) and composed of adenine, ribose, and two phosphate groups.
type II muscle fibers (fast twitch):
Muscle fiber type that contracts quickly and is used mostly in intensive, short-duration exercises.
type I muscle fibers (slow twitch):
A muscle fiber characterized by its slow speed of contraction and a high capacity for aerobic glycolysis.
glycolytic pathway
metabolic process in which glucose is broken down to produce energy anaerobically.
oxidative pathway:
A metabolic process in which oxygen combines with lactic acid, resynthesizing glycogen to produce energy aerobically.
tissue
A collection of similar cells and their intracellular substances.
triglycerides
The storage form of fat made up of three fatty acids and a glycerol group
tendon
Connective tissue that attaches muscle to bone.
ligament
Connective tissue that connects bone to bone or bone to cartilage.
respiratory system
System consisting of the lungs and air passageways, which supplies oxygen to the body and removes carbon dioxide.
Hemoglobin
oxygen-transporting protein in red blood cells
