09a. Chronic Ads - Aerobic Cardiovascular

Question 1

Define Heart Rate

Answer 1

Amount of times the heart beats per minute

Question 2

Define Stroke Volume

Answer 2

The amount of blood pumped out of the left ventricle per beat

Question 3

What does haemoglobin do

Answer 3

carry oxygen in the blood

Question 4

What does the Left Ventricle do

Answer 4

pumps oxygenated blood out of the heart to the body

Question 5

What carries oxygen in the blood

Answer 5

haemoglobin

Question 6

What type of muscle fibre does not fatigue easily and has increased blood supply

Answer 6

Slow twitch fibres

Question 7

What pumps oxygenated blood out of the heart to the body

Answer 7

Left Ventricle

Question 8

What are the smallest blood vessels that supply tissues with oxygenated blood and carry blood containing waste away from tissues

Answer 8

capillaries

Question 9

Which energy system is associated with having a high LIP

Answer 9

aerobic

Question 10

What is LIP?

Answer 10

the last point of balance where LA accumulation is equal to removal

Question 11

What is the movement of gases from areas of high concentration to areas of low concentration.

Answer 11

Gaseous Exchange

Question 12

What is the amount of times the heart beats per minute

Answer 12

Heart Rate

Question 13

What is the amount of blood pumped out of the left ventricle per beat

Answer 13

Stroke Volume

Question 14

What is the amount of blood pumped out of the left ventricle per minute

Answer 14

Cardiac Output

Question 15

List the 4 aerobic cardiovascular chronic adaptations

Answer 15

Increased LV Volume, capillarisation of the heart, red blood cells and haemoglobin levels

Question 16

Explain how an aerobic cardiovascular adaptation increases performance for an aerobic athlete.

Answer 16

Increased ability to work at a higher intensity aerobically for longer, therefore delaying increased contributions from the anaerobic energy systems and accumulation of metabolic by products eg. H+Ions therefore increasing performance. Eg. higher average speed in the race

Question 17

List three aerobic vascular chronic adaptations

Answer 17

Increased capillarisation of the heart, red blood cells and haemoglobin levels

Question 18

Explain how an aerobic cardiovascular adaptation increases performance for an anaerobic athlete.

Answer 18

Increased ability to get oxygenated blood to the muscles during recovery therefore increased removal of wastes, delivery of nutrients and increased recovery rate therefore can train/compete again optimally sooner.

Question 19

How does having an increased LV volume directly assist performance?

Answer 19

Increased SV at maximal intensity, therefore increased oxygenated blood out of the heart and to the muscles per beat

Question 20

How does having an increased capillarisation of the heart directly assist performance?

Answer 20

Increased oxygenated blood to the heart therefore increased ability of the heart to contract

Question 21

How does having an increased red blood cells and haeomoglobin directly assist performance?

Answer 21

Increased ability to carry oxygen in the blood, therefore increased ability to get oxygen to working muscles

Question 22

What happens to resting heart rate as a result of increased stroke volume

Answer 22

It decreases
