Lesson Details

Key learning points

Aerobic exercise is exercise that uses oxygen for energy over extended periods, like running or cycling.
Anaerobic exercise is high-intensity exercise that doesn't rely on oxygen, such as sprinting or weightlifting.

Common misconception

Pupils are unsure about situations when the body works aerobically and when it works anaerobically.

Aerobic exercise requires oxygen from the air we breathe to totally break down glucose to release energy for exercise. This is the most efficient mechanism but requires exercise to be at a low/ moderate intensity whereas high intensity is anaerobic.

Keywords

Aerobic exercise - exercise that involves prolonged physical activity using oxygen to produce energy, typically performed at moderate intensity e.g. long distance running
Anaerobic exercise - exercise that involves short bursts of high intensity activity where the body’s demand for oxygen exceeds the supply available e.g. sprinting up a hill
Lactic acid - a by-product of anaerobic respiration that accumulates in muscles during intense exercise, contributing to muscle fatigue and soreness
