energy continuum

Question 1

energy continuum

Answer 1

a term used to describe which energy system used for different types of physical activity

Question 2

what is the ATP-PC/ anaerobic glycolytic threshold

Answer 2

where the ATP-PC system is exhausted and AG energy system takes over (usually 10 secs)

Question 3

what is the anaerobic glycolytic/ aerobic threshold

Answer 3

it is where the anaerobic system is exhausted and the aerobic system takes over (usually 3mins)

Question 4

what energy system is used when performance lasts less than 10 seconds and example

Answer 4

ATP-PC

100m, long jump

Question 5

what energy system is used when performance last 8-90secs and example

Answer 5

ATP-PC and anaerobic glycolytic

200m, 400m gym floor routine

Question 6

what energy system is used when performance lasts 90secs to 3mins and example

Answer 6

anaerobic glycolytic and aerobic

1500, a round of boxing

Question 7

what energy system is used when performance lasts 3+ mins and example

Answer 7

aerobic

marathon, cross country, skiing

Question 8

difference between anaerobic respiration and aerobic respiration

Answer 8

anaerobic respiration is quicker but it is an inefficient process producing only 2 ATP per glucose molecule and muscles fatigue quicker due to the build up of lactic acid

Question 9

which muscles fibres are used for anaerobic respiration

Answer 9

fast twitch

Question 10

which muscles fibres are used for aerobic respiration

Answer 10

slow twitch

Question 11

differences in ATP generation between fast and slow twitch muscle fibres

Answer 11

• slow twitch main pathway fro ATP production is in aerobic system
• fast twitch main pathway fro ATP production is anaerobic energy system
• slow twitch produces max amount of ATP (up to 36 ATP)
• fast twitch ATP production is in the absence of oxygen is not efficient (only 2 ATP)
• slow twitch production is slow but these fibres are more endurance based so less likely to fatigue
• fast twitch production of ATP is fast but cannot last for long as these fibres have least resistance to muscle fatigue
