Energy Systems Flashcards
what is the base energy currency
adenosine triphosphate
what is the first line of fuel support?
fast released carbs in upper GI
what is the second line of fuel support?
slower released carbs in the lower GI
what is the third line of fuel support
fats
more complex in structure and takes more effort to make ATP
4th line of fuel support
blood glucose or glycogen in muscle or liver
5th line of fuel support
proteins (last option)
ATP-PC system
anaerobic, uses small amounts of ATP already in muscle
Lactic acid system
anaerobic glycolysis
ATP from glucose found in blood stream or in muscles or liver as glycogen
limited by production of lactic acid
aerobic pathway
main method of producing ATP
breakdown of glucose and fatty acids
can make large amounts of ATP but requires o2
Training ATP-PC system
atrophy of type 1 muscles
hypertrophy of type 2 muscles
more actin and myosin
improved recruitment of type 2 motor neurons
Training Anaerobic Lactic Acid System
improved endurace
increases lactose tolerance and lactic acid removal
higher tolerance for acidity in blood due to hydrogen ion buffering
can create large o2 debt
training aerobic system
improve CV fitness
increase muscle stores of glycogen and myoglobin
increased size and density of mitochondria
ability to use triglycerides as energy
increased blood and stroke volumes
