Consider Option C:  A feeling of muscle burning during intense exercise

  • The feeling of muscle burning during intense exercise is a common sensation associated with lactate accumulation in the muscles, which is an immediate physiological response to high-intensity training.

Other Options:

  • A is incorrect: Decreased heart rate during recovery relates to cardiovascular recovery, not lactate levels
  • B is incorrect: Increased breathing rate relates to ventilation response, not directly to lactate
  • D is incorrect: Oxygen consumption increases, not decreases, during exercise
