What determines which energy system predominates during exercise?
✔✔The intensity and duration of the activity determine whether the ATP-PC, anaerobic
glycolytic, or aerobic system predominates.
How does the body transition between energy systems during exercise?
✔✔The body transitions between energy systems based on changes in exercise intensity and
duration, from the ATP-PC system at high intensity to the aerobic system at low intensity.
How can active recovery help with lactic acid removal?
✔✔Active recovery helps by maintaining blood circulation, which facilitates the removal of
lactic acid from muscles and promotes quicker recovery.
What is the purpose of the aerobic system during exercise?
✔✔The aerobic system provides energy for long-duration, moderate-intensity exercise by
breaking down carbohydrates and fats with oxygen.
1
,How does carbohydrate availability affect endurance performance?
✔✔Carbohydrates are a key energy source for the aerobic system, and their availability helps
sustain energy levels during prolonged exercise.
What is the difference in energy production between aerobic and anaerobic exercise?
✔✔Aerobic exercise uses oxygen to produce energy through the breakdown of carbohydrates
and fats, while anaerobic exercise produces energy without oxygen, resulting in quicker fatigue.
What is the role of phosphocreatine in the ATP-PC system?
✔✔Phosphocreatine is broken down to regenerate ATP quickly, providing energy for short
bursts of high-intensity exercise.
How long does it take for the ATP-PC system to recover fully?
✔✔It typically takes about 3-5 minutes for the ATP-PC system to fully recover after intense
exercise.
How does interval training benefit the energy systems?
✔✔Interval training enhances the efficiency of both anaerobic and aerobic systems by improving
the body’s ability to switch between different energy pathways.
2
,What is the recovery time for the anaerobic glycolytic system?
✔✔The anaerobic glycolytic system takes longer to recover, typically requiring 30-60 minutes
for lactic acid to clear and for energy stores to be replenished.
What is the effect of dehydration on energy systems during exercise?
✔✔Dehydration impairs the efficiency of all energy systems by reducing blood flow, limiting
oxygen delivery, and decreasing metabolic efficiency.
How does oxygen debt relate to post-exercise recovery?
✔✔Oxygen debt refers to the increased oxygen intake after exercise needed to replenish energy
stores, remove lactic acid, and restore normal body function.
How does the energy continuum explain the use of multiple energy systems during a 400-meter
race?
✔✔During a 400-meter race, the ATP-PC system provides immediate energy, the anaerobic
glycolytic system supplies energy as lactic acid builds, and the aerobic system contributes to the
recovery during the final stages.
3
, What causes the "burning" sensation during intense anaerobic exercise?
✔✔The burning sensation is caused by the accumulation of lactic acid in muscles, which lowers
the pH and affects enzyme function, leading to fatigue.
How does recovery from high-intensity exercise differ from recovery after endurance exercise?
✔✔Recovery from high-intensity exercise focuses on replenishing phosphocreatine stores and
removing lactic acid, while endurance recovery focuses on restoring glycogen and reducing
muscle inflammation.
How does creatine supplementation enhance ATP-PC system performance?
✔✔Creatine supplementation increases the phosphocreatine stores in muscles, allowing for
longer periods of high-intensity exercise and quicker recovery of ATP.
How does the body replenish glycogen stores after exercise?
✔✔Glycogen stores are replenished through the intake of carbohydrates post-exercise, helping to
restore energy levels for future activity.
