CREATINE PHOSPHATE ANAEROBIC GLYCOLYSIS FAT OXIDATION

4 ENERGY SYSTEMS �CREATINE PHOSPHATE (ATP reservoir) LASTS 0 -10 SECONDS �ANAEROBIC GLYCOLYSIS (2 ATP) LASTS 10 SECONDS – 3 MINUTES �AEROBIC GLYCOLYSIS (36 ATP) LASTS 3 MINUTES – 20 MINUTES �FAT OXIDATION (460 ATP) LASTS GREATER THAN 20 MINUTES

ATP – The ENERGY MOLECULE �ADENOSINE TRIPHOSPHATE �The energy in food is not directly turned into energy. �The food we eat are broken down into ATP molecules. �Phosphates/ATP are our energy molecules. �ATP turns into ADP (Adenosine Diphosphate) when used.

Creatine Phosphate (0 -10 seconds) �Called the energy reservoir. �Creatine floats freely in our cells. �Does not rely on oxygen. �These are “excess” molecules formed by other energy systems. �During this period our body starts “warming” up for the next energy system.

ANAEROBIC GLYCOLYSIS �Lasts 10 seconds to 3 minutes. �ANAEROBIC – without oxygen. �GLYCOLYSIS – sugar/glucose breakdown. �Produces small amounts of ATP (2). �Produces Lactic Acid.

AEROBIC GLYCOLYSIS �Lasts 3 minutes to 20 minutes. �Produces 36 ATP �Aerobic – With oxygen – sugar/glucose breakdown

FAT OXIDATION (Beta) � Greater than 20 minutes. � Creates 460 ATP. � This system uses oxygen to breakdown fats.

AEROBIC VS. ANAEROBIC (WITHOUT OXYGEN) AEROBIC (WITH OXYGEN) ACTIVITIES CONTINUUM

WEIGHT LOSS BURN MORE CALORIES THAN YOU CONSUME This can be done in three ways: 1. Eat less. 2. Exercise more. 3. Eat less, and exercise more.

CALORIES �It is not healthy to lose more than 2 -3 pounds per week. � 3500 CALORIES = 1 LB. �Average diet is 2000 calories per day. 14, 000 calories per week. �Through exercise or dieting, you have to find a deficit in calories of 7, 000 calories in order to lose two pounds.
