1. ENERGY SYSTEMS

2. DEFINITION qEnergy could be described as “ the ability to work”

3. THE ENERGY CYCLE Carbohydrate manufactured by plant and eaten by man. Carbohydrate consumed Digested - becomes glucose and enters the blood. Glucose rich blood arrives at the pancreas stimulating insulin. Glucose not required for energy Turned into glycogen and stored Blood level of glucose correct for current needs Glucose used for energy Blood glucose drops causing appetite to be stimulated Carbohydrate consumed

4. ENERGY SUPPLY THE LIVING BODY REQUIRES A CONSTANT SUPPLY OF ENERGY IN ORDER TO FUNCTION - FOR MOVEMENT, GROWTH, REPAIR etc. THE IMMEDIATE SOURCE OF ENERGY COMES FROM THE ENERGY RICH MOLECULE ADENOSINE TRIPHOSPHATE (ATP), WHICH IS STORED IN THE MUSCLE.

5. ENERGY SUPPLY IN ORDER TO MAINTAIN THE ENERGY SUPPLY (ATP) HAS TO BE RESYNTHESIZED. THE PROCESS OF BREAKING DOWN AND RESTRUCTURING (ATP) CAN OCCUR WITH OR WITHOUT THE USE OF OXYGEN.

6. ENERGY SYSTEMS qAnaerobic (2 types) qHigh intensity short duration qThis creates an (0 2 ) debt (has to be repaid ) qUses compounds already stored in the muscle as its fuel qThese are :- phosphocreatine glycogen

7. ADENOSINE TRY PHOSPHATE THE BODIES ONLY FUEL FOR MUSCLE CONTRACTION ONCE A MUSCLE CONTRACTION TAKES PLACE THE AT P MUST BE RESTORED IN ONE OF THREE WAYS.

8. qPhosphate system qVery short, high intensity, “explosive” Activities e.g.. Heavy weights,short sprint, high jumping qThe fuel is phosophocreatine (PC) stored for immediate use ENERGY SYSTEMS

9. PHOSPHATE SYSTEM

10. qPC gives max 10 sec of effort but restored quickly 50% 30 secs 100% 2 mins qNo waste products ENERGY SYSTEMS

11. qLactate system qhigh intensity short duration activities e.g, heavy weights, body conditioning sustained sprint, uphill running qthe fuel is :- glycogen stored in the muscle,liver & blood ENERGY SYSTEMS

12. LACTATE SYSTEM

13. qFatigue 30 secs exhaustion 1 min qByproduct - lactic acid (incomplete breakdown of glycogen) qLactic acid - toxin, partially removed within a short time but around 2 hours to remove completely ENERGY SYSTEMS

14. qAerobic qlow intensity long duration activities e.g, walking, swimming, jogging qthis system can produce large amounts of energy qthis system uses (O 2 ) when (O 2 ) is supplied at the same rate as it is used ENERGY SYSTEMS

15. AEROBIC SYSTEM BEFORE LACTIC ACID PRODUCTION

16. qThis system uses carbohydrates (glycogen,) and fats qwaste products - (CO 2 ) & water can be easily removed qtakes 2 - 3 mins to reach this state qlasts 2 hours maximal work longer sub maximal ENERGY SYSTEMS

17. EXPERIMENT

18. STAND UP SIT DOWN STAND UP THEN SIT DOWN. WAIT 10 SECCONDS THEN REPEAT

19. BURPEES START BURPEE EXERCISE AND CONTINUE FOR AS LONG AS POSSIBLE.

20. RUN ON SPOT KEEP JOGGING AT A SLOW STEADY PACE
