MODULE 3 Flashcards
(47 cards)
the physiological processes
- building and repairing new tissues
- muscle contraction
- organ function
- food absorption, etc.
the energy obtained from the food we intake is transferred to a high-energy molecule called _______________
adenosine triphosphate (ATP)
where the ATP can be stored in
muscles
stored in the body is limited and therefore needs to be replenished constantly
ATP
The ATP stored in the muscles can only supply energy for activities with _________________________ of work
approximately 2-3 seconds
replenish the stored ATP to sustain the demands of physical activities
the 3 energy systems
the 3 energy systems
- ATP-CTP system
- anaerobic glycolysis system
- aerobic energy system
used by the ATP-CP system that is stored in muscles to resynthesize ATP, the main supplier of energy
creatine phosphate (CP)
also known as glucose
carbohydrates
since the ATP-CP system stored in the muscles are limited, this will then support the supply of energy
anaerobic glycolysis system
this system used carbohydrates (glucose) in the muscle to create energy
anaerobic glycolysis
after about _____________, the ____________________ that uses oxygen to create energy will help continue the activity
30 seconds
aerobic energy system
the 3 energy systems may dominate at different times depending on the ___________ and __________________ of the physical activity
length and intensity
during high power, short duration physical activities, the ATP-CP system is also known as the ___________________
phosphagen system
this is probably what your body used on your first run in the relay game
ATP-CP system
also known as glycolytic system that fuels moderate power, moderate duration physical activities
anerobic glycolysis system
uses muscle __________ as fuel that can be used for up to ___________ of maximum effort and exerting further effort up to __________________________
glycogen
30 seconds
50 seconds
also known as the oxidative system, the source of ATP for physical activities that last longer than 3 minutes
aerobic energy system
this system mainly uses carbohydrates and fats to create energy supply for bodily functions at rest and during low power, long duration activities
aerobic energy system
draws energy from food nutrients
human body
plays an important role in the function of the energy systems of the body
nutrition
examples of physical activities in ATP-CP system
sprinting, throwing a ball, weightlifting
examples of physical activities in anaerobic glycolysis system
swimming, cycling, badminton, tennis, football
examples of physical activities in aerobic energy system
8-hour shift, 3-mile walk
