energy systems

Question 1

what are the three metabolic pathways?

Answer 1

atp-pc
glycolysis
cellular respiration

Question 2

atp-pc

Answer 2

quick, intense muscle contraction
(anaerobic alactic)
draws on processes deep within the muscle fibre itself

Question 3

glycolysis

Answer 3

longer bursts of energy
(anaerobic lactic)
partial breakdown of glucose, with lactic acid as a byproduct

Question 4

cellular respiratioin

Answer 4

endurance events
(aerobic)
involves oxygen and the complete breakdown of glucose
yields large amounts of ATP

Question 5

atp →

Answer 5

adp + p + energy

Question 6

anaerobic

Answer 6

without oxygen

Question 7

aerobic

Answer 7

with oxygen

Question 8

atp + creatine →

Answer 8

PC + ADP

Question 9

slow-twitch

Answer 9

muscle fibres are red or dark in colour and generate and relax tension relatively slowly
able to maintain a lower level of tension for long duration
deal for activities such as long-distance swimming, cycling and running

Question 10

fast-twitch

Answer 10

muscle fibres are more pale in colour, have the ability to tense and relax quickly can generate large amounts of tensions with relatively low endurance levels
ideal for the fast, powerful muscle contractions needed for activities such as short sprints, powerlifting, and explosive jumping

Question 11

type 1

Answer 11

muscle fibres generate energy slowly, are more fatigue-resistant

Question 12

type 2a

Answer 12

allow for high-speed energy release

Question 13

type iib

Answer 13

suited to speed, strength and power type activities
