Energy for Exercise

Question 1

define the energy continuum

Answer 1

describes the relative contribution of each of the 3 energy systems to re-synthesise ATP according to duration and intensity

Question 2

show which energy systems represent which line of the energy continuum

Answer 2

Question 3

define intermittent exercise

Answer 3

a performer can move between any energy systems depending on the intensity and duration of the activity and fuels available

Question 4

describe the use of recovery periods

Answer 4

• ## timeouts/ breaks between quarters/ half- times/ breaks between sets

Question 5

describe the factors that effect the contribution of energy systems

Answer 5

• position of player = goalkeeper predominantly aerobic/ midfielder anaerobic glycolytic
• tactics and strategies = man to man predominantly anaerobic glycolytic/ zonal marking more aerobic
• level of competition = high comp is anaerobic/ low comp is aerobic
• structure = field games are more aerobic due to large pitch/ court games ae higher intensity more anaerobic

Question 6

define EPOC

Answer 6

volume of O2 consumed post- exercise to return the body to its pre-exercise state

Question 7

describe alactacid component of epoc

Answer 7

• replenish ATP and PC stores (4L O2 (50%= 30secs, 100%= 3 mins)
• replenish myoglobin with oxygen (1 min, 0.5L O2)
