AEROBIC POWER

Question 1

aerobic power

Answer 1

maximum rate of energy prodution from the aerobic system

energy produced in the presence of oxygen

Question 2

role of cardiovasular and respiratory systems in producing aerobic power

Answer 2

well trained cardiovasular and respiratory systems allow the athlete to produce atp aerobically and maintain a high intensity for longer, and have an increased capacity to efficiently replenish anaerobic systems.

Question 3

factors affecting aerobic power

Answer 3

greater percentage of slow-twitch fibres - slow-twitch fibres work aerobically therefore the more a person has, the greater their ability to work aerobically
males have high aerobic power due to having larger lungs (increased oxygen uptake), higher haemoglobin levels (increased oxygen transport), and mroe muscle mass therefore mitochondria (increased oxygen utilisation)
aerobic power peaks in person’s early to mid 20’s and then decreases as age increases due to decreased elastisity of lungs (decreased oxygen uptake), decreased haemoglobin (decreased oxygen transport) and decreased muscle mass (decreased oxygen utilisation)

muscle fibre type, sex, age

Question 4

tests for aerobic power

Answer 4

yo-yo intermittent recovery test
cooper 12-minute run tests
VO2 max treadmill test
20m shuttle run test
20m multi stage test

Question 5

training methods

Answer 5

continuous, long-interval, HIIT, and circuit training
work:rest ratio of 1:1 or 2:1
