Aerobic And Anaerobic Excerise Flashcards
What does aerobic mean?
With oxygen
What does anaerobic mean?
Without oxygen
What does the anaerobic respiratory system do during exercise?
The anaerobic respiratory system supplies energy very quickly. This system breaks down glucose into lactic acid. It produces energy very quickly.
Glucose → ? + ?
Glucose → energy + lactic acid
What does lactic acid do?
The lactic acid energy system produces the majority of the energy for moderate to high intensity activities such as running 400 metres.
Why is lactic acid bad?
Lactic acid is a fatiguing by-product of this energy pathway and causes pain and discomfort in the working muscles.
Why do so many athletes take ice baths?
The use of cold conditions pushes blood flow to deep tissue, preventing swelling and pain in the arms and legs. When blood flow returns to these areas it helps to flush out lactic acid and other impurities built up during performance.
Name three ways to recover from running
Cool down
Refuelling
Ice baths
What does the aerobic respiratory system do during exercise?
The aerobic respiratory system is responsible for producing the majority of our energy while our bodies are at rest or taking part in low-intensity exercise for long periods of time such as jogging or long-distance cycling.
Glucose + oxygen → ? + ? + ?
Glucose + oxygen → energy + water + carbon dioxide
What helps athletes gain energy from running for long periods?
Glucose from carbohydrates and fats supply the energy for the aerobic energy system and can supply energy for long periods of time.
