Terms in this set (37)



Explain how energy is provided, allowing the athlete to 1. Stored ATP
complete the shot put (3 marks) 2. Alactic system / ATP-PC system / Phosphocreatine system / ATP-CP system
3. PC breakdown
4. To creatine and phosphate / C and P
5. Energy used / released to perform the contraction / re-synthesis for ATP


What is the effect on ATP and PC stores of short periods A ATP / PC levels decrease / fall during exercise.
of high intensity exercise followed by recovery periods B Insufficient Stores don't fully recover / not enough ATP / PC resnythesised in 30
lasting up to 30 seconds? Justify your answer. (3 marks) seconds of rest.
C (during exercise) ATP / PC supplying energy.
D (during exercise) PC breakdown for ATP resynthesis.
E (during recovery) ATP / PC resynthesised during rest / recovery.
F (during recovery) Insufficient recovery time to fully replenish / 2-3 minutes for
full recovery.
Sub-max 2 marks For Points C - F

A sport such as tennis uses the ATP-PC system for energy Advantages
production. Outline the advantages and the A. Energy released quickly / immediately / doesnߣt require oxygen.
disadvantages of the ATP-PC system. 4m release of energy - too vague
B. ATP resynthesised quickly / PC / Phosphocreatine stores recover quickly/ATP-
PC recover quickly.
C. Allowing high intensity exercise to be completed again in short space of time /
after a brief recovery period.
D. No waste / by-products formed.
Disadvantages
E Limited stores of PC.
F High intensity exercise can only be completed for brief period of time / 8 - 10
seconds.
G Full recovery takes up 2-3 minutes.

Gymnastic events can last up to 90 seconds. Explain how Anaerobic / without oxygen
the majority of energy is provided for these events. (7 (during first few seconds) stored ATP splits / breaks down initially / ATP breaks
marks) down to
ADP + P + energy.
ATP-PC / system / phosphocreatine system / alactic system.
PC = C + P(i) + energy / creatine + phosphate / PC broken down.
Energy used for ATP resynthesis / ADP + P + energy = ATP / ADP + PC = ATP + C.
Lasts 5-10 seconds / limited supply.
Lactic acid system / Lactate anaerobic system.
Do not accept lactic system
Glycogen / glucose breakdown.
Glycolysis.
To pyruvate / pyruvic acid.
Lactate / lactic acid formed.
