aerobic capacity

Question 1

What is v02 Max?

Answer 1

The maximum volume of oxygen that can be taken in and used per minute

Question 2

What happens when graph starts to peak and decrease?

Answer 2

They had reached their v02 Max

Question 3

What factors affect v02 max?

Answer 3

Physiological, lifestyle, genetics

Question 4

Why doe physiology have an effect?

Answer 4

Hypertrophy (bigger heart), big stroke volume, volume/ amount of haemolgibn (carries oxygen, maeglobin- capillary density (bloody vessels that carry things through muscles more effectively) muscles can use more oxygen
slow twitch muscle fibres

Question 5

Why does lifestyle have an effect?

Answer 5

exercise loads
smoking can have a disadvantage
methods of training

Question 6

Why does genetics have an effect?

Answer 6

inherit v02 max from parents

Question 7

Why does gender have an effect?

Answer 7

Males have a higher v02 Max due to size/ age as older v02 Max declines

Question 8

What is OBLA?

Answer 8

Start to build lactic acids in your blood, when you strart to build lactic acid system (jogging increase intensity). Lactate threshold (the point start to build lactic acid)

Question 9

What is the lactate tolerance?

Answer 9

The amount of lactic acid they can put up with, then took them on training program-

Question 10

What is the lactate threshold?

Answer 10

When they start using lactic acid threshold.

Question 11

What is the relationship between v02 and obla?

Answer 11

High v02 max will delay obla (lactic acid threshold). Delay lactic acid at higher speed; m Farah accumulates lactic acid later

Question 12

What is the benefit of a high v02 max?

Answer 12

removes a lot of lactic acid as it builds up.

Question 13

What are heart rate training zones?

Answer 13

Allows us to set a precise heart rate

easy to monitor

Question 14

What is karovens principle?

Answer 14

HRMAX= 220- age
karovens formula t
Training HR= RHR+% (HRmax-rhr)
for example = 68+ 80% of (202-68)
training hr= 175
Takes your age into consideration and resting heart rate/ whereas heart rate takes 20/30 year olds with the same intensity

Question 15

What is continuous training?

Answer 15

Steadt state, prolonguedperiod of exercise (running, swimming, rowing)
Develops aerobic system and type 1 muscle
good for endurance athletes
20-80 minutes
continuous run but intensity is varied vy alerting pace/ gradient (fartlek run) good for games players

Question 16

What is high intensity interval training (HIT)?

Answer 16

periods of work and rest, can be used to develop aerobic and anaerobic fitness
alters; duration of work (if aerobic will be su-max, if anaerobic will be max)interval
alteration of rest
number of reps
number of sets
intensity of work period
intensity of rest period
duration- 5 secs to 8 minutes
duration of rest 1;1

Question 17

What are the benefits of hit training?

Answer 17

Higher intneisyt than continuous so adaptations ofccur quicker more calories burnt but not safe for those who have medical condition

Question 18

What are the adaptations to v02 max?

Answer 18

Cardio vascular, respriatory

metabolic function and muscle-sketletal system

Question 19

What are the adaptions to cardio-vascular?

Answer 19

Cardiac hypertrophy, increased elasticity of arterial walls, increased blood plasma volume, increased haemoblin, , capilirations of alveoli and type fibres.

Question 20

Why is hypertrophy good?

Answer 20

heart pumps out more blood, heart rate will decrease (bradycardia) stroke volume will increase

Question 21

Why is increased elastic good for arterial walls?

Answer 21

Better vasodilation and vasoconstrioctn of blood vessels, decreased resting blood pressure

Question 22

Why is increased blood plasma volume good?

Answer 22

lower blood viscootust, better blood flow

Question 23

Why is an increase in haemolgibn goof?

Answer 23

Increased oxygen capacity- better gaseous exchange

Question 24

Why is capolisation of alveoli good?

Answer 24

Increased surface area for blood flow, increased gaseous exchange

Question 25

What is the effect on the respiratory system?

Answer 25

Tronger respiratory muscles, increased mechanics of breathing (increased maximal lung volumes)
Increased diffusion of gases t the lungs eternal respiration, increase alveoli) better gaseous exchange

Question 26

What are the adaptations to the musculoskeletal system?

Answer 26

type/fibre hypertophy- greater aerobic energy work and delayed faitgue
increased size and density of mitochondria, breakdown of fats
Increased myoglobin levels- increased storage of oxygen in the muscles
increased glycogen and fats stores (break fat down in mitrocondria), more fuel- increases fuel stroes
increased cartilage thickness- better joint movement and better impact
Increased ligament and tendon strengt0 better joint stability
increased bone strength

Question 27

What are the adaptations of metabolic function?

Answer 27

Increased aerobic enzyme, increases breakdown of fats and glycogen quicker
Increased fat mass, increased metabolic rate- are calories burnt
increased insulin resistance, improved glucose tolerance (reduced risk of diabetes)
