Show Worked Solution

Consider Option A: ATP-PCr

  • The ATP-PCr system is dominant for high-intensity activities lasting 0-10 seconds

Other Options:

  • B is incorrect: The Lactic Acid system dominates from 10-60 seconds
  • C is incorrect: The Aerobic system is for longer duration activities over 2 minutes
  • D is incorrect: While there is some overlap, ATP-PCr clearly dominates this short duration
