What does ATP stand for?
Adenosine Triphosphate
What does ATP do?
Gives our muscles energy used during exercise
What is ATP?
A molecule containing Adenosin and 3 phospates to create energy
How does ATP produce energy?
When the bond breaks between the second and the third phosphate energy is released and creates ADP. A-P-P-P
What is ADP?
Is adenosine and two phosphates and a separate part which is and organic phosphate. A-P-P Pi
What is the ATP breakdown?
A-P-P-P A-P-P x P A-P-P Pi
What are the fuels used to resynthesize ATP?
Carbohydrates, fats, proteins and creatine phosphate
What is carbs stored as?
Blood - glucose Muscles - glycogen Excess - Adipose tissue (liver)
What is fats stored as?
Blood - fatty acids Muscles - triglycerides Excess - adipose tissue
When are the fuel sources used in exercise?
Carbohydrates used during exercise, fats are used during rest and in exercise upwards of 3 hours and proteins are used in very long endurance events
What are the three energy systems?
ATP-PC, anaerobic glycolosis and aerobic
does atp pc require oxygen
Does not require oxygen
does anaerobic require oxygen?
Does not use oxygen
does aerobic use oxygen
Uses oxygen
What is meant by the term energy system interplay?
Means that the three systems work together to produce energy for the body while doing exercise
Basketball - when do the energy systems dominate
ATP-PC - when they go for the jump ball Anaerobic - sprinting from one end to the other Aerobic - lets them keep running throughout the game
How long does each system last?
ATP PC lasts 10-15 secs Anaerobic lasts 10 sec - 2 min Aerobic lasts indefinitely
Why do we use carbs instead of fats for fuel?
Fats make more ATP but use too much oxygen making them inefficient and carbs use less oxygen therefore can produce ATP at a faster rate
How much CP is stored in the muscles?
10 seconds worth
How to train atp-pc system
resistance plyometrics circuit short interval speed
how to train anaerobic system
medium intervals resistance circuit
how to train aerobic system
long interval fartlek continuous circuit
What intensity does the atp pc system operate in?
maximal
when is atp pc system used?
short bursts of exercise
