energy systems!!!

Question 1

the three systems

Answer 1

• ATP-PC
• anaerobic glycolysis
• aerobic (glycolysis/lipolysis)

Question 2

ATP-PC fuel source

Answer 2

phosphocreatine (PC/CP)
- no cost to break down

Question 3

PC - storage

Answer 3

stored in the muscle cells as PC

Question 4

how long does the ATP-PC system last? + sporting example

Answer 4

6-10 seconds
HIGH INTENSITY
100m sprint
shotput
javelin

Question 5

rate/yield of ATP-PC

Answer 5

FASTEST rate
LOWEST yield

Question 6

by-products of the ATP-PC system

Answer 6

creatine and inorganic phosphate (Pi): the build up of Pi can slow down muscle contractions, which causes a decrease in force production and power output

Question 7

anaerobic glycolysis fuel source

Answer 7

glycogen/glucose (carbohydrates)

Question 8

glucose - storage

Answer 8

stored as gylcogen in the muscles/liver

Question 9

how long does the anaerobic glycolysis system last? + sporting example

Answer 9

1-2 minutes
HIGH-MID INTENSITY
100m swim
400m race

Question 10

rate/yield of anaerobic glycolysis

Answer 10

MODERATE rate
MODERATE yield

Question 11

by-products of anaerobic glycolysis

Answer 11

VERY BAD ONES!!
lactic acid:
- lactate
- hydrogen (H+) ions
very very bad! build up impairs enzyme function and muscle contractions, meaning intensity will drop

Question 12

aerobic system fuel source

Answer 12

OXYGEN REQUIRED
glycogen/glucose (carbohydrates)

Question 13

how long does the aerobic glycolysis system last? + sporting example

Answer 13

**2mins + **
LOW INTENSITY
marathons
1500m
road bike race

Question 14

rate/yield of aerobic glycolysis

Answer 14

SLOW rate
HIGH yield

Question 15

by products of the aerobic system

Answer 15

• water
• carbon dioxide
• heat
