What is ATP?
energy molecule
ATP is a high-energy compound that breaks down to release energy used for muscular contraction.
We then have 3 different systems that work simultaneously together to ______________ ATP.
Resynthiszie
The two anaerobic energy systems are…..
lactic (glycolysis) system
ATP-PC
in the lactic acid system, fatigue happens because…
absence of oxygen
Carbohydrates in their simplest form are called…
Glycogen
lactic acid can stay in your muscles for up to ______ hours. This time is significantly shortened if you do ______. some examples of this are
24 to 72 hours
ACTIVE RECOVERY.
STRETCHING
MESSAGE
ICE BATH
LOW-INTENSITY CARDIO
The muscle fibres most used for the Lactic Acid system are fast twitch fibres (Type IIa) which are _______ in colour.
WHITE/PINK
ATP is made up of 4 molecules, they are:
- Adenosine + ribose (only used as the last result)
- Phosphate 1
- Phosphate 2
- Phosphate 3
an ATP molecule with 2 phosphates is called…
Adenosine Diphosphate
ATP
Adenosine Triphosphate
The phosphate that has detached from an ATP molecule is now known as
inorganic phosphate
ATP-PC system = ??? intensity
High
how long does the ATP-PC system last
2-12 seconds
What does the PC in the ATP-PC system stand for
Phosphocreatine
what colour are the muscle fibers in the ATP-PC system
White- Fast twitch
By-products of the ATP-PC stystim
Heat
intensity of the ATP-PC system
Very High
what is the main difference between the anaerobic and aerobic system
aerobic uses oxygen anaerobic doesnt
3 activities where the ATP-PC system is donnantant
shot put
javelin
weightlifting
3x activitys where the anaerobic Glycolytic system (lactic acid system) is most dominant?
swimming 400m
800m sprint
cycling
what system kicks in when you exercise for longer than 12 secs
lactic asid
where is the energy for the lactic acid fuel stored in the body
in the liver and mustles
charbs=
glycose
F or F- the lactic asid systim used oxygen
FAULSE
