Q

how ATP-PC (phosphate energy system) works

A

uses a stored molecule in the muscle called creatine phosphate (CP) to resynthesise ATP amount of ADP used from ATP grows.
Chemical bond between phosphate and creatine is broken, releasing energy that is used to reconstitute ATP from ADP

17
Q

excess CHO is stored as

A

adipose tissue (fat)

18
Q

glycogen broken down chemically to

A

pyruvic acid

19
Q

during breakdown of aneraobic glycolysis system releases energy which is used to resynthesise …… where pyruvic acid is converted into …

A

ATP in the absence of oxygen…lactic acid

20
Q

what happens to the pyruvic acid when there’s an absence of oxygen

A

it gets converted into lactic acid

21
Q

what do Lactate and hydrogen ion do

A

they build up the working muscles over time inhabits sporting performance

22
Q

how does lactate and hydrogen ions create fatigue

A

causes inhibition of the muscle contractions of working muscles.

23
Q

what to do when lactate and hydrogen ions create fatigue

A

the athlete has to stop the activity
-this allows oxygen to break down the lactate and hydrogen ions to continue muscular effort.

24
Q

what system is the major contributor to produce energy when lactate and hydrogen ions accumulation

A

The aerobic system

25
Q

the aerobic system duration

A

60-120 seconds onwards

26
Q

intensity of the aerobic system

A

sub-maximal continuous

27
Q

aerobic system examples

A

1500m run & swim, cross country, triathlon

28
Q

what can aerobic system create

A

38 molecules of ATP from 1 glucose molecule

29
Q

how many molecules can glycolysis create

A

only 2

30
Q

krebs cycle is

A

when the pyruvic acid is further broken down in citric acid cycle

31
Q

what are the 3 stages of the aerobic energy production

A

Aerobic glycolysis, Kreb Cycle (citric acid cycle), Electron transport system.

32
Q

what happen aerobic glycolysis

A
33
Q

in the aerobic glycolysis what haven to the lactic acid

A

it does not accumulate

34
Q

what happens in the Kreb Cycle (citric acid cycle)

A

Pyruvic acid is broken down to carbon dioxide, with further energy release.

35
Q

what happens in the electron transport system

A

heat, water and substantial amounts of ATP are formed

36
Q

how long it takes to repair creatines full restoration

A

in 2-3 minutes

37
Q

30 seconds rest for creatine repair is

A

80%-90% restoration

38
Q

ATP-PC (adenosine triphosphate-phosphocreatine) is a system used

A

by muscles to produce energy during short, intense bursts of activity.

39
Q

what is the aerobic system

A

When the body needs to reduce effort or stop an activity due to the buildup of lactate and hydrogen ions,
-it becomes main source of energy production.

40
Q

what is Anaerobic glycolysis system

A

When the Phosphocreatine stores are empty and the Phosphate System can no longer provide most of the energy, the Anaerobic Glycolysis system becomes the primary source of energy production
