09a. Chronic Ads - Aerobic Cardiovascular Flashcards
Define Heart Rate
Amount of times the heart beats per minute
Define Stroke Volume
The amount of blood pumped out of the left ventricle per beat
What does haemoglobin do
carry oxygen in the blood
What does the Left Ventricle do
pumps oxygenated blood out of the heart to the body
What carries oxygen in the blood
haemoglobin
What type of muscle fibre does not fatigue easily and has increased blood supply
Slow twitch fibres
What pumps oxygenated blood out of the heart to the body
Left Ventricle
What are the smallest blood vessels that supply tissues with oxygenated blood and carry blood containing waste away from tissues
capillaries
Which energy system is associated with having a high LIP
aerobic
What is LIP?
the last point of balance where LA accumulation is equal to removal
What is the movement of gases from areas of high concentration to areas of low concentration.
Gaseous Exchange
What is the amount of times the heart beats per minute
Heart Rate
What is the amount of blood pumped out of the left ventricle per beat
Stroke Volume
What is the amount of blood pumped out of the left ventricle per minute
Cardiac Output
List the 4 aerobic cardiovascular chronic adaptations
Increased LV Volume, capillarisation of the heart, red blood cells and haemoglobin levels
Explain how an aerobic cardiovascular adaptation increases performance for an aerobic athlete.
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
List three aerobic vascular chronic adaptations
Increased capillarisation of the heart, red blood cells and haemoglobin levels
Explain how an aerobic cardiovascular adaptation increases performance for an anaerobic athlete.
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.
How does having an increased LV volume directly assist performance?
Increased SV at maximal intensity, therefore increased oxygenated blood out of the heart and to the muscles per beat
How does having an increased capillarisation of the heart directly assist performance?
Increased oxygenated blood to the heart therefore increased ability of the heart to contract
How does having an increased red blood cells and haeomoglobin directly assist performance?
Increased ability to carry oxygen in the blood, therefore increased ability to get oxygen to working muscles
What happens to resting heart rate as a result of increased stroke volume
It decreases
