Study Notes

Energy Systems

  • The aerobic system accounts for 99% of energy production throughout your life.
  • The aerobic system has the highest capacity and duration.
  • The ATP-PC system has the lowest inertia.
  • The ATP-PC system has the highest rate/power of ATP production.
  • The ATP-PC system fatigues very quickly.
  • The ATP-PC system has the slowest recovery time.

Energy System Substrates

  • The ATP-PC system uses phosphocreatine (PCr) as its substrate.
  • The anaerobic glycolytic system uses glucose as its substrate.
  • The oxidative system uses mostly carbs and fats, with some proteins, as its substrate.

Energy System Function

  • The aerobic system is always functioning.
  • The aerobic system provides the majority of energy throughout your life.
  • The anaerobic system is affected by high-intensity, short-duration exercises.
  • The aerobic system is affected by low-intensity, long-duration exercises.

Energy Buffer and ATP Production

  • Creatine phosphate acts as an energy buffer and helps maintain ATP levels.
  • The enzyme creatine kinase catalyzes the breakdown of PCr.
  • The end product of glycolysis is pyruvate.
  • The main function of the creatine-phosphate shuttle is to rapidly replenish ATP.

ATP Production and Lactate

  • PCr levels decrease during exercise.
  • Adenylate kinase plays a role in ATP production by reversibly catalyzing the reaction of 2ADP to ATP and ADP.
  • The purpose of the shuttle system is to rapidly replenish ATP during high-intensity exercises.
  • The enzyme lactate dehydrogenase is responsible for converting pyruvate into lactate.
  • Type 1 muscle fibers are more predominant in slow twitch muscle fibers.
  • Type 2 muscle fibers are more predominant in fast twitch muscle fibers.
  • The primary source of lactate production during muscle contraction is the anaerobic glycolytic system.

Lactate Production and Removal

  • The anaerobic system is primarily used during anaerobiosis.
  • The primary method of lactate removal is through the oxidation of lactate in the heart, liver, and kidneys.
  • Type 2 muscle fibers lead to increased lactate production due to their high glycolytic capacity.
  • Type 1 muscle fibers lead to decreased lactate production due to their high oxidative capacity.
  • The approximate concentration of lactate in the blood is 1-2 mmol/L.
  • The enzyme lactate dehydrogenase is responsible for converting lactate into pyruvate.
