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

Lactic acid and recovering from exercise

Physical education

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

{{ }} acid is produced in the muscles when insufficient oxygen is supplied during exercise.

explosive events requiring speed and power.

Place these events in order to describe what happens during anaerobic exercise.

A high carbohydrate meal, active cool down and an ice bath help speed up {{ }} after intense exercise.
