working at a moderate intensity so that the body has time to utilise oxygen for energy production, allowing the body to work for a continuous period, e.g. long-distance events, or duration of a match

working at a high intensity without oxygen for energy production, therefore limited energy so work period will be short, e.g. sprinting up the wing in a football match

a by-product of energy production-formed when the body is exercising anaerobically at high intensity

when lactate levels in the blood/muscle rise due to increased work intensity, e.g. moving from aerobic to anaerobic exercise

Aerobic and anaerobic exercise

Lactic acid and recovering from exercise

This unit will explore the impact of varying the intensity and durations of exercise upon the build up of lactic acid and recovery rates. Exercises will be classified as either aerobic (with sufficient oxygen) or anaerobic (without sufficient oxygen).

Anatomy and physiology: anaerobic and aerobic exercise

a by-product of anaerobic respiration that accumulates in muscles during intense exercise, contributing to muscle fatigue and soreness

the amount of extra oxygen required to remove the lactic acid and replace the body's reserves of oxygen

the point at which intensity of exercise triggers a build up of lactic acid in the muscles and blood due to working anaerobically with insufficient oxygen

time required to repair the damage to the body caused by training or competition
