SOC18 Aerobic, Anaerobic Exercise And Energy Stores 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 anaerobic exercise?
Anaerobic activities are usually short but intense e.g. sprinting, lifting wights and jumping
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 cramp?
painful, involuntary contraction of a muscle, usually caused by fatigue.
What is the aerobic equation?
Glucose + oxygen = carbon dioxide + water + energy
What is the anaerobic equation?
Glucose = energy + lactic acid
What is oxygen debt?
The amount of oxygen needed wt the end of physical activity to break down lactic acid
What are the two main types of energy?
- fats
- carbohydrates
What are carbohydrates?
Carbohydrates are the main energy source for both high-intensity (anaerobic) exercise and moderate-intensity (aerobic) exercise
What are fats?
Fats can provide energy for only moderate-intensity (aerobic) exercise for long periods over 2 hours
What are fats broken down into?
Fatty acids, which are absorbed into your blood and delivered to your cells.
What are carbohydrates broken down into?
Glucose or glycogen, which can be absorbed through the walls of your small intestine and into your blood.
