AEROBIC & ANAEROBIC EXERCISE & ENERGY SOURCES (SOC 18) 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 sternous exercise when the body is exercising anaerobically at high intensity.
WHAT IS CRAMP?
Painful, involuntary contraction of a muscle, usually caused by fatigue.
WHAT DO WE NEED IN OUR MUSCLES TO WORK?, WHAT IS STORED IN OUR LIVER?
Muscles need energy to work. Glucose is Stored in the Liver, they store it as glycogen. Then is transferred back into glucose.
WHAT IS AEROBIC RESPIRATION?
When our body releases energy, it’s called aerobic respiration. (Instead of sweat it’s water).
WHAT IS THE EQUATION FOR AEROBIC & AENAROBIC EXERCISE / ENERGY SOURCES?
Equation = Glucose + Oxygen + Carbon Dioxide + Water + Energy = Sun.
Glucose & Oxygen are brought to Muscles in Blood.
Glucose + Energy + Lactic Acid.
Are anaerobic activities short?
Anaerobic activities are usually short but intense.
What sports are related to anaerobic exercise / energy sources?
Anaerobic exercises are sports such as long jump or sprinting etc…
What is lactic acid?
Lactic acid is toxic, it eventually causes muscle ache. It causes cramp and cannot work anymore, you need to rest and recover before starting exercise again.
