AEROBIN AND AEROBIC METABOLISM

TYPES OF METABOLISM

THE BODY USES ANAEROBIC AND AEROBIC METABOLISM DURING EXERCISE TO PROVIDE THE NECESSARY FUEL FOR THE MUSCLES

ANAEROBIC METABOLISM IS THE CREATION OF ENERGY THROUGH THE COMBUSTION OF CARBOHYDRATES IN THE ABSTENCE OF OXYGEN. THIS OCCURD WHEN THE LUNGS CON NOT PUT ENOUGH BOXYGEN INTO THE BLOODSTREAM TO MEET THE ENERGY DEMANDS OF THE MUSCLES. IN GENERAL, IT IS USED ONLY FOR SHORT PERIODS OF ACTIVITY.

WHEN THERE IS NOT ENOUGH OXYGEN IN THE BLOODSTREAM, GLUCOSE AND GLYCOGEN CAN NOT BE BROKEN DOWN COMPLETELY INTO CARBON DIOXIDE AND WATER. INSTEAD, LACTIC ACID IS PRODUCED, WHICH CAN ACCUMULATE IN THE MUSCLES AND DEGRADE MUSCLE FUNCTION.

AEROBIC METABOLISM IS THE WAY THE BODY GENERATES ENERGY THROUGH THE COMBUSTION OF CARBOHYDRATES, AMINO ACIDS AND FATS IN THE PRESENCE OF OXYGEN. COMBUSTION MEANS BURNING, SO WHAT THE BODY DOES IS BURN SUGARS, FATS AND PROTEINS FOR ENERGY. AEROBIC METABOLISM IS USED FOR SUSTAINED PRODUCTION OF ENERGY FOR EXERCISE AND OTHER BODILY FUNCTIONS.

ANAEROBIC AND AEROBIC

THE GENERAL METABOLISM OF THE BODY INCLUDES MUSCLE CONTRACTION, RESPIRATION, BLOOD CIRCULATION, MAINTENANCE OF BODY TEMPERATURE, DIGESTION OF FOOD, WASTE DISPOSAL AND FUNCTIONS OF THE BRAIN AND NERVOUS SYSTEM. THE SPEED AT WHICH YOU BURN CALORIES IS CALLED THE METABOLIC RATE.

DURING EXERCISE NOT ONLY INCREASES THE METABOLISM IN THE MUSCLES, BUT ALSO IN THE RESPIRATORY SYSTEM AND THE CIRCULATORY SYSTEM. GREATER HEART RATE AND FASTER BREATHING FREQUENCY ARE NEEDED TO DELIVER OXYGEN AND NUTRIENTS TO THE MUSCLES, SO THE BODY MUST ALSO WORK HARDER TO AVOID OVERHEATING. FOR EXAMPLE, THROUGH SWEATING.

ANAEROBIC METABOLISM CAN ONLY USE GLUCOSE AND GLYCOGEN, WHILE AEROBIC METABOLISM CAN ALSO BREAK DOWN FATS AND PROTEINS. INTENSE EPISODES OF EXERCISE IN THE ANAEROBIC ZONE AND IN THE AREA ABOVE 85% OF YOUR MAXZIMUM HEART RATE USE ANAEROBIC METABOLISM TO NOURISH THE MUSCLES.

SOME SPORTS 

THE LIFTING OF WHEIGHTS AND OTHER STRENGTH EXERCISES, WHEN EXTENUATING EFFORTS ARE MADE IN A SHORT PERIOD OF TIME.

WHEN RUNNING OR PEDALING VERY FAST, TO GET ENOUGH ENERGY.
IN THE SPRINTS, TO FEED THE MUSCLES DURING TAHT BRIEF PERIOD OF SPEED.
