SOC 18-Aerobic, Anaerobic Excerise And Energy Sources Flashcards
What is glucose?
A major source of energy for most cells in the body.
What is aerobic respiration?
The process of releasing energy from glucose, using oxygen.
What is anaerobic respiration?
The process of releasing energy from glucose, without oxygen.
What is aerobic exercise?
Working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period, e.g. long-distance events.
What is lactic acid?
A colourless acid produced in muscle tissues during strenuous exercise when the body is exercising anaerobically at high intensity.
What is a cramp?
Painful, involuntary contraction of a muscle, usually caused by fatigue.
Anaerobic excerise
Exersising at 80-90% of your Heart rate-without presence of oxygen
Complex carbohydrates
contain longer chains of sugar molecules than simple carbohydrates-long term
Simple carbohydrates
broken down quickly by the body to be used as energy-short term
Carbohydrates use in the body
Main source of energy-broken down into glucose or glycogen
Fats uses in the body
Ususally probide most of the body energy needs, brokwn down into fatty acids which are absorbed in the blood
Energy source
Carbohydrates and fats
Carbohydrates-anaerobic or aerobic?
Both, high intensity anaerobic excerise and moderate intensity aerobic excerise
Fats-anaerobic or aerobic?
Fats can provide energy for only moderate-intensity (aerobic) exercise
for long periods over 2 hours
