Aerobic and anaerobic exercise聽- WJECAerobic respiratory system
Depending upon whether the body uses oxygen or not in order to perform physical activities determines if the activity is aerobic (with oxygen) or anaerobic (without oxygen).
The aerobicWith oxygen. 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 鈫 energy + water + carbon dioxide
Glucose from carbohydrates and fats supply the energy for the aerobic energy system and can supply energy for long periods of time.
Carbohydrate food sources include rice, bread, potatoes, bananas and energy drinks. Fat food sources include butter, oils, cheese, milk and nuts.
Question

Any one of the following: 5,000 metres run, 10,000 metres run, marathon, race walking, triathlon, biathlon.
Energy balance equation
