SHORT-TERM EFFECTS OF EXERCISE Flashcards
HOW DOES THE SHORT-TERM EFFECTS WORK IN THE MUSCULAR SYSTEM
1) DURING ANAEROBIC EXERCISE YOU PROUDCE LACTIC ACID
2) IF YOU USE YOUR MUSCLES ANAEROBICALLY FOR TOO LONG LACTIC ACID STARTS TO BUILD UP THIS LEADS TO A RISE IN THE (LACTATE LEVELS) IN THE BODY WHICH IS CALLED LACTATE ACCUMULATION
3) LACTIC ACID BUILD UP MAKES YOUR MUSCLE PAINFUL AND CAUSES MUSCLE FATIGUE
4) TO RECOVER THE MUSCLE FATIGUE AND REMOVE THE LACTIC ACID YOU NEED A CERTAIN AMOUNT OF OXYGEN
5) THIS AMOUNT OF OXYGEN IS CALLED THE OXYGEN DEBT
6) TO REPAY OXYGEN DEBT YOU WILL NEED TO SLOW DOWN OR COMPLETLY STOP THE ACTIVITY YOU ARE DOING, WHICH WILL GRADUALLY AFFECT YOUR PERFORMANCE
HOW DOES SHORT-TERM EFFECT WORKS ON THE RESPIRATORY SYSTEM
1) DURING EXERCISE YOUR DEPTH AND RATE OF BREATHING INCREASE
2) THIS MEANS MORE OXYEGEN IS TAKEN IN AND TRANSFERRED TO THE BLOOD, WHICH HELPS MEET THE INCREASED DEMAND FOR OXYGEN
3) IT ALSO HELPS YOU TO BREATH OUR EXTRA CO2 PRODUCED DURING AEROBIC RESPIRATION
4) THESE CHANGES ALLOW YOU TO DO AEROBIC ACTIVITY FOR LONG PERIODS OF TIME
5) IF YOU HAVE BEEN DOING ANAEROBIC ACTIVITY, YOUR BREATHING RATE AND DEPTH WILL REMAIN HIGHER THAN NORMAL UNTIL YOU TAKE IN ENOUGH OXYGEN TO ‘PAY OFF’ OXYGEN DEBT
HOW DOES THE SHORT-TERM EFFECT WORK ON THE CARDIOVASCULAR SYSTEM
1) DURING EXERCISE YOUR HEART RATE AND STROKE VOLUME BOTH INCREASE
2) THIS LEADS TO AN INCREASE IN YOUR CARDIAC OUTPUT
3) THIS INCREASES THE BLOOD AND OXYGEN SUPPLY TO YOUR MUSCLES, SO THEY CAN RELEASE THE
ENERGY THEY NEED FOR PHYSICAL ACTIVITY, IT ALSO REMOVES CARBON DIOXIDE FROM THE MUSCLES AND IT TAKES IT TO THE LUNGS TO BE BREATHED OUT
4) THE HEART RATE, STROKE VOLUME AND CARDIAC OUTPUT WILL REMAIN HIGHER THEN NORMAL AFTER EXERCISE UNTIL ANY OXYGEN DEBT IS PAID OFF
HOW DOES THE CARDIOVASCULAR AND RESPIRATORY SYSTEM WORK TOGETHER IN SHORT-TERM EFFECTS
-DURING EXERCISE AND INNMEDIATLY AFTER MORE OXYGEN IS DELIVERED TO THE MUSCLES THAN NORMAL AND CARBON DIOXIDE IS BREATH OUT OF THEM
-THESE CHANGES MAINTAIN A HIGH CONCENTRATION GRADIENT, AFTER YOU BREATH IN THERE IS A LOT MORE OXYGEN IN THE ALVEOLI THAN THE CAPILLARIES AND A LOT MORE CARBON DIOXIDE IN THE CAPILLARIES THAN THE ALVEOLI
-THESE ALLOWS DIFFUSION OF THE GASES TO HAPPEN MUCH QUICKER DURING EXERCISE
-THESE PROCESSES HELP YOU TO RELEASE ENOUGH ENERGY TO EXERCISE AEROBICALLY AND TO RECOVER FROM OXYGEN DEBT AFTER ANAEROBIC ACTIVITY
HOW IS MORE O2 DELIVERED
1) BREATHING RATE AND DEPTH INCREASE, SO MORE OXYGEN IS DELIVERED TO THE ALVEOLI IN THE LUNGS
2) CARDIAC OUTPUT ALSO INCREASES SO BLOOD PASSES THROUGH THE LUNGS AT A FASTER RATE, AND PICKS UP THE EXTRA OXYGEN FROM THE ALVEOLI TO THEN DELIVER IT TO THE MUSCLES
HOW IS MORE CO2 REMOVED
1) INCREASED CARDIAC OUTPUT MEANS THAT THE BLOOD CAN TRANSPORT CARBON DIOXIDE FROM THE MUSCLES TO THE LUNGS AND MORE QUICKLY
2) HERE IT MOVES BACK INTO THE ALVEOLI AND THE HIGHER BREATHING RATE AND DEPTH ALLOW IT TO BE QUICKLY BREATHED OUT
