Aerobic And Anaerobic System Flashcards
What important roles does James’ blood play in maintaining his performance?
Removes waste products- Co2
Regulating body temp
Transporting oxygen and glucose to his working muscles
What is aerobic respiration?
Activities that use oxygen as the main fuel source
5 mile run will use this system to provide energy to the working muscles
What is the word equation of aerobic respiration?
Glucose+oxygen–> energy+carbon dioxide+water
What is anaerobic respiration?
Activities that do not require oxygen to produce energy
Short in duration, usually require power such as sprinting for the finish line at the end of the 5 mile run
Word equation for anaerobic respiration
Glucose –> energy + lactic acid
Following anaerobic respiration, James’ blood will?
Transport glucose to his working muscles
Remove waste products (such as lactic acid) to prevent muscle cramps
Regulate his body temp
After the 5 mile run, James will have an elevated breathing rate and depth. Why?
The body needs to remove the by-products of exercise (lactic acid and CO2) and this is called an oxygen debt
What is the recovery process to return the body back to its pre-exercise state?
The lungs- increase the depth and frequency of breathing to remove carbon dioxide and intake more oxygen to break down lactic acid
Sweat- increase of sweat production to cool the body and regulate James’ body temp
Other bodily functions- urine and faeces also remove waste products
What is lactic acid
Produced in the muscle tissues during strenuous exercise, as a result of insufficient oxygen available
What is the lactic acid threshold
The time an anaerobic performer can cope with lactic acid for, before it hinders muscular contractions.
Define recovery rate
The time taken for the body systems to return to resting levels/rates after exercise
What is an oxygen debt
The amount of extra oxygen consumed during recovery above that which would normally consumed during rest
