what the 3 energy systems are

Question 1

what is the phosphate energy system (ATP-PC) DURATION

Answer 1

5-15 seconds depending on intensity

Question 2

the intensity of ATP-PC

Answer 2

maximal effort

Question 3

The phosphate energy system provides ATP production when

Answer 3

ATP stores already in the muscles are used up

Question 4

The phosphate (ATP-PC) energy system provides the bulk of ATP production during what efforts

Answer 4

powerful or explosive efforts

Question 5

examples of ATP-PC

Answer 5

sprinting short distances, High jump, Long Jump

Question 6

how ATP-PC (phosphate energy system) works

Answer 6

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

Question 7

repairing of creatine occurs

Answer 7

occurs when activity end

Question 8

when does the anaerobic glycolysis system contributes majority of energy

Answer 8

when phosphocreatine stores are depleted and the phosphate system no longer can provide the bulk of energy production.

Question 9

what intensity is the anaerobic glycolysis

Answer 9

high intensity - maximal activities

Question 10

duration of anaerobic glycolysis

Answer 10

10-60 seconds

Question 11

examples of the anaerobic glycolysis

Answer 11

400m sprint, repeated sprints in team games

Question 12

what do anaerobic glycolysis use carbohydrates as

Answer 12

as its fule

Question 13

what are the by products of anaerobic glycolysis

Answer 13

lactate and hydrogen ions

Question 14

in the anaerobic glycolysis CHo is broken down in the digestive system to produce what

Answer 14

glucose

Question 15

anaerobic glycolyisis is also known as

Answer 15

lactic acid

Question 16

anaerobic glycolysis travels through the blood streams and stored in muscles and liver as

Answer 16

glycogen

Question 17

excess CHO is stored as

Answer 17

adipose tissue (fat)

Question 18

glycogen broken down chemically to

Answer 18

pyruvic acid

Question 19

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

Answer 19

ATP in the absence of oxygen…lactic acid

Question 20

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

Answer 20

it gets converted into lactic acid

Question 21

what do Lactate and hydrogen ion do

Answer 21

they build up the working muscles over time inhabits sporting performance

Question 22

how does lactate and hydrogen ions create fatigue

Answer 22

causes inhibition of the muscle contractions of working muscles.

Question 23

what to do when lactate and hydrogen ions create fatigue

Answer 23

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

Question 24

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

Answer 24

The aerobic system

Question 25

the aerobic system duration

Answer 25

60-120 seconds onwards

Question 26

intensity of the aerobic system

Answer 26

sub-maximal continuous

Question 27

aerobic system examples

Answer 27

1500m run & swim, cross country, triathlon

Question 28

what can aerobic system create

Answer 28

38 molecules of ATP from 1 glucose molecule

Question 29

how many molecules can glycolysis create

Answer 29

only 2

Question 30

krebs cycle is

Answer 30

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

Question 31

what are the 3 stages of the aerobic energy production

Answer 31

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

Question 32

what happen aerobic glycolysis

Answer 32

(simmiler to anaeroic glycolysis) pyruvic acid is broken down by presence of o2 . -

Question 33

in the aerobic glycolysis what haven to the lactic acid

Answer 33

it does not accumulate

Question 34

what happens in the Kreb Cycle (citric acid cycle)

Answer 34

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

Question 35

what happens in the electron transport system

Answer 35

heat, water and substantial amounts of ATP are formed

Question 36

how long it takes to repair creatines full restoration

Answer 36

in 2-3 minutes

Question 37

30 seconds rest for creatine repair is

Answer 37

80%-90% restoration

Question 38

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

Answer 38

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

Question 39

what is the aerobic system

Answer 39

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.

Question 40

what is Anaerobic glycolysis system

Answer 40

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
